Abstract

Hydrogen generation from formic acid using nanoscale zero-valent iron (nZVI) represents a promising route for low-cost and sustainable hydrogen production. However, the effect of sodium borohydride (NaBH₄) to ferric chloride (FeCl₃) molar ratio on nZVI synthesis and performance remains insufficiently explored. This study investigated how varying NaBH₄:FeCl₃ molar ratios affect nZVI synthesis characteristics and its hydrogen generation efficiency from formic acid, which acts as a safe and easily handled hydrogen carrier. nZVI was synthesized through a one-step liquid-phase chemical reduction method using NaBH₄:FeCl₃ ratios ranging from 4.4:1 to 8.8:1. UV–Vis spectroscopy indicated that the 4.4:1 ratio yielded the highest nZVI formation, reflecting optimal reduction efficiency and particle formation. Hydrogen generation experiments conducted in a closed reactor equipped with a water displacement system revealed that nZVI synthesized at the 4.4:1 ratio achieved the maximum hydrogen volume (98 mL), which progressively declined to 53 mL at the 8.8:1 ratio. These findings demonstrate that precursor molar ratios significantly influence nZVI formation, stability, and reactivity toward hydrogen evolution. An optimal NaBH₄:FeCl₃ ratio of 4.4:1 was identified for maximizing nZVI formation and hydrogen volume, providing valuable insights for developing scalable formic acid–based hydrogen generation systems.

Abstract

Rising atmospheric CO₂ concentrations necessitate the development of efficient and economically viable carbon capture materials. Metal-organic frameworks (MOFs) offer strong potential due to their tunable pore structures and accessible metal sites. In this work, Fe-MOF, Cu-MOF, and bimetallic Fe/Cu-MOF were synthesized via a solvothermal route and systematically evaluated for CO₂ adsorption performance. The materials were characterized using SEM-EDX, FTIR, XRD, BET, and TGA to establish correlations between structural properties and adsorption behavior. CO₂ uptake was investigated under varying pressure (1-5 bar), adsorbent dosage (0.2-0.5 g), and temperature (40-50 °C). Among the three adsorbents, Fe/Cu-MOF exhibited the highest adsorption capacity, reaching 3.22 mg.g-¹ at 5 bar, outperforming Fe-MOF (2.54 mg.g-¹) and Cu-MOF (2.35 mg.g-¹). Adsorption increased markedly with pressure, showed non-linear dependence on dosage due to site underutilization and diffusion limitations, and decreased with increasing temperature, indicating an exothermic physisorption-dominated process. BET analysis revealed that Fe/Cu-MOF possessed the highest surface area (19.4 m².g-¹) and pore volume (0.0489 cm³.g-¹), while XRD and FTIR confirmed successful incorporation of both metal centers, generating chemically heterogeneous adsorption sites. Kinetic analysis demonstrated that CO₂ uptake follows a pseudo-first-order model, consistent with surface-controlled physisorption. The enhanced performance of Fe/Cu-MOF is attributed to synergistic effects arising from dual-metal coordination, improved pore connectivity, and increased availability of active adsorption domains. These findings highlight the potential of bimetallic Fe/Cu-MOFs as promising candidates for pressurized CO₂ capture applications and provide insight into structure-performance relationships governing gas adsorption in defect-rich MOF systems.

Abstract

Intensive mechanical stirring, commonly used for gold nanoparticle (AuNP) recovery, suffers from drawbacks such as mechanical wear and high operational costs. Self-propelled catalytic composites capable of autonomous motion present a promising alternative, yet their applicability and influence on AuNP recovery efficiency remain insufficiently explored. Hence, this study aimed to fabricate palm shell-supported manganese dioxide (MnO2)composites and investigate the effect of their dosage on AuNP recovery via hydrogen peroxide reduction. The composites were characterized using Field Emission Scanning Electron Microscopy with Energy Dispersive X-Ray Spectroscopy (FESEM-EDX) to assess their morphology, particle size, and elemental composition, while UV-Vis spectroscopy was used to monitor AuNP formation through localized surface plasmon resonance (LSPR) responses. Results revealed that a composite dosage of 0.2 g/L produced the sharpest LSPR peak at 530 nm, indicating the highest yield of spherical AuNPs with particle sizes ranging from 20 to 80 nm. Motion analysis showed that the composites exhibited autonomous bubble-propelled motion at an average speed of 25.5 µm/s, following linear and semi-circular trajectories that enhanced mass transfer and AuNP recovery efficiency. Overall, palm shell-supported MnO2 composites demonstrate great potential as an alternative to conventional mechanical stirring-based methods for recovering AuNPs.

Abstract

Bi3NbO7 has been widely studied as a bismuth-based photocatalyst for degradation of organic pollutants. However, the fast recombination of photo-excited carriers limits its photocatalytic performance. In this work, the CuBi2O4/Bi3NbO7 heterojunction was successfully fabricated, and its photocatalytic performance was evaluated by degradation of TC under stimulated sunlight. The optimal TC degradation efficiency of 85% was obtained on CuBi2O4/Bi3NbO7 heterojunction with CuBi2O4 mass ratio of 10% at the condition as initial TC concentration of 40 mg/L and photocatalyst dosage of 1 g/L. This optimal TC degradation efficiency is greatly higher than that of bulk Bi3NbO7 with the reaction rate constant reached 0.035 min-1 which is 3.7 times as that of Bi3NbO7. The photocatalytic degradation mechanism that based on type-II heterojunction was proposed. This work provided a promising strategy to design highly efficient photocatalysts for environmental remediation. Copyright © 2026 by Authors, Published by BCREC Publishing Group.

Abstract

Converting biogenic carbon and captured CO₂ into synthesis gas (syngas) via ethanol dry reforming (EDR) offers a pathway to low-carbon fuels, but catalyst instability and coking remain key barriers. Palm-oil fuel ash (POFA), a silica-rich agro-industrial waste, was investigated in this study as a support material for cobalt loading and to evaluate its performance in EDR. Co/POFA catalysts containing 5-20 wt % Co was prepared by ultrasonic-assisted incipient wetness, calcined, and tested for EDR at 750 °C. Nitrogen physisorption, FT-IR, and post-reaction TGA were employed to correlate catalyst texture, surface chemistry, and thermal stability with ethanol and CO₂ conversion, as well as H₂ and CO yields.  Maximal, durable activity occurred at the intermediate Co loading (15 wt%), where ethanol and CO₂ conversions were ~72% and 80% initially and remained ~50% and 68% after 5 h, the ~48% H₂ yield was sustained, consistent with a loading that maximizes accessible Co sites without incurring mesopore transport limitations. Lower loading of 5 wt % Co was site-limited and heavily coked, whereas excessive loading of 20 wt % Co showed rapid deactivation attributed to pore blockage and cobalt agglomeration despite minimal coke. Optimizing cobalt dispersion on conditioned POFA enables stable syngas production under demanding EDR conditions, validating Co/POFA as a viable waste-derived catalyst for circular, CO₂-utilizing hydrogen generation.

Abstract

This research focuses on enhancing hydrogen production via the photocatalytic method using a TiO2 catalyst with nitrogen doping and morphology modification to improve efficiency. Nitrogen-doped TiO2 nanowires (NTN) were successfully hydrothermally grown on titanium foil to produce thin-film photocatalysts for the visible-light-driven production of hydrogen. Nitrogen incorporation induced bandgap narrowing, from 3.18 eV to 2.85 eV, by introducing N 2p states close to the valence band, thereby increasing visible-light absorption. Structural analyses confirmed the formation of lattice strain and oxygen vacancies associated with substitutional doping, while the one-dimensional nanowire architecture enhanced charge transport and reduced carrier recombination pathways. The optimized N–TiO2 NWs demonstrated the highest hydrogen evolution rate of 2.385 µmol/cm2 under 180 minutes of visible-light irradiation, corresponding to a hydrogen evolution rate of 0.795 µmol/cm²/h, without a noble-metal co-catalyst. A strong correlation is established between nitrogen-induced surface electronic modification and the enhancement of nanowire-driven charge separation. This study presents a recyclable and scalable thin-film photocatalyst design suitable for future solar hydrogen production systems. Copyright © 2026 by Authors, Published by BCREC Publishing Group.

Abstract

The environmental impact of waste palm cooking oil (WCO) has prompted extensive research into its potential applications, as it remains a significant pollutant, particularly in urban areas. This study investigates the synthesis of polysulfide using elemental sulfur and WCO as a sustainable method to repurpose these waste materials. The synthesized polysulfide showed effective methylene blue (MB) dye adsorption from wastewater, with adsorption performance assessed by varying the sulfur content (wt%) and dosage levels. Characterization techniques, including Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDS), were employed to analyze its structural and morphological properties. At the same time, UV-Vis spectrophotometry was used to measure the color removal efficiency. The highest removal rate of 78% was achieved at 70 wt% sulfur using 5 g of polysulfide in a 5 mg/L MB solution. The adsorption followed the Temkin adsorption isotherm (R2 = 0.96). Post-adsorption FTIR analysis confirmed that the degradation followed a physisorption mechanism, as no changes in functional bonds were observed. By simultaneously addressing WCO and sulfur waste, this study underscores the potential of polysulfide as an effective, sustainable adsorbent for wastewater treatment.
