Abstract

The Climate Village Program (ProKlim) is a national scale program in order to encourage the community and all parties to take concrete actions to improve resistance to the negative impacts of climate change. In the village of Nusukan in particular RW 13 will be promoted by the Climate Village Program (ProKlim). To support the program, the procurement of a mini garden is carried out as an effort to move society and all parties in the face of climate change. The impact of this activity is to increase public knowledge and understanding of change climate and its impacts, as a real adaptation effort so that it can improve the degree of public health in the face of climate change, environment of RW 13 Nusukan, and can reduce GHG (Greenhouse Gas) emissions.

Abstract

Hexagonal TiO2/SiO2 Porous Microplates have been successfully synthesized by incorporation of Ti precursors into SiO2 synthesized from Si precursors in a gelatin-CTAB mixture via the hydrothermal method. The prepared samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), EDX, nitrogen adsorption-desorption and Fourier transform infrared spectroscopy (FTIR). The sample has a surface area of 735 m2/g, pore volume of 0.67 cc/g, and pore diameter of 3.2 nm, according to the results of the characterization of hexagonal TiO2/SiO2 porous microplates. The transformation of SiO2 microspheres into hexagonal TiO2/SiO2 porous microplates is revealed by a microparticle size increase of 84% and the transition of Si−O bonds into Ti−O and Si−O as measured by FTIR. The photocatalytic activity of hexagonal TiO2/SiO2 porous microplates resulted in 81.15% photodegradation of methylene blue under UV light irradiation within 60 min, which was 21 % better than SiO2.

Abstract

TiO2 material has an important position in the processing of methylene blue waste because it is economical, has abundant polymorphs, high sustainability and supports green chemistry applications. Mesoporous TiO2 is a porous material that has higher effectiveness than other TiO2 because the pore structure has a large diameter at the nano scale (2-50 nm) with a regular shape so that the surface area and pore volume are greater than the average for other TiO2. The synthesis of mesopore TiO2 material has so far used the sol-gel route with synthetic pore directing agents such as P123 which can be replaced with gelatin as a cheaper and safer pore directing agent with high sustainability and abundance. Based on the description above, this research aims to photodegrade methylene blue using mesoporous TiO2 (m-TiO2) nanoparticles which were prepared by the sol–gel method using gelatin and P123 as template. X-ray diffraction (XRD), scanning electron microscopy (SEM), Electron dispersive X-Ray (EDX), and UV–vis spectroscopy techniques were used to characterize the samples. Photocatalytic activities of samples for methylene blue degradation were investigated. The catalyst before and after regeneration will be studied so that the effect of regeneration on the results of methylene blue photocatalysis with m-TiO2 can be determined. XRD results confirmed the formation of the anatase and rutile phase for the TiO2 nanoparticles, with crystallite sizes larger after regeneration in the range of 9–21 nm. The large particle size was after regeneration due to the promotion by high temperature treatment. TiO2 nanoparticles showed the best photocatalytic activity on the first use to 91% and remained stable after four cycles with photodegradation efficiency up to 76% based on the measured UV-Vis spectroscopy. TiO2 as synthesis could be the best candidate for catalyst with the high performance after multicycle regeneration. Copyright © 2024 by Authors, Published by BCREC Publishing Group.

Abstract

This study explores the development of nanostructured photocatalytic materials based on cobalt–iron (CoFe1-2) and cobalt–nickel (CoNi1-1) systems for the degradation of methylene blue, a persistent organic pollutant commonly found in textile wastewater. As the textile industry contributes significantly to environmental pollution through the discharge of recalcitrant dyes, this work aims to offer an effective and sustainable solution via visible-light-driven photocatalysis. The synthesis strategy employed a hard-template approach using mesoporous silica-gelatin composite (SPG-20), prepared from a mixture of P123 and gelatin under acidic conditions. Following hydrothermal treatment and calcination, the SPG-20 template was acid-activated to enhance surface reactivity. Metal precursors—Co(NO₃)₂.6H₂O with either Fe(NO₃)₃.9H₂O or Ni(NO₃)₂.6H₂O—were infiltrated into the template with citric acid as a chelating and carbon-forming agent. The composite underwent controlled thermal treatment to embed metal species into a confined carbon matrix, followed by alkaline etching to remove the silica scaffold and yield CoFe1-2 and CoNi1-1 carbon nanostructures. Comprehensive characterizations, including XRD, FTIR, BET, UV-DRS, and UV–VIS spectroscopy, revealed that the materials exhibited nanocrystalline domains with low crystallinity and high specific surface area, favorable for photocatalytic activity. BET analysis indicated a greater surface area in CoFe1-2 (104.526 m²/g) than in CoNi1-1 (83.160 m²/g), correlating with a higher number of available active sites. The band gap of CoFe1-2 (1.180 eV) supports efficient visible-light absorption, which, coupled with its higher microporosity, enables superior methylene blue degradation (85% within 90 minutes) compared to CoNi1-1 (75%). Control experiments in the absence of light showed minimal degradation, confirming that the reaction is photocatalytic in nature. Adsorption kinetics followed a pseudo-first-order model, with CoFe1-2 also exhibiting a higher adsorption capacity (171.184 mg/g). These findings demonstrate the potential of template-assisted synthesis in producing tunable, high-performance photocatalysts for practical applications in sustainable textile wastewater treatment.
