Abstract

Photoelectrochemical (PEC) is a new renewable energy technology that converts H2O into hydrogen and oxygen gas with the help of sunlight. A photoelectrochemical cell device consists of three main components, one of which is the photoanode. One of the materials that can be used as a photoanode is ZnO which has good electrical properties and is non-toxic. Nanorods-structured ZnO has the advantage of being able to increase light absorption due to its high surface area. However, the resulting performance is still quite low. So it is necessary to make modifications to the photoanode, one of which is by adding aluminium material to ZnO NRs, which has the potential to increase the conductivity of PEC in the production of H2 and O2 in H2O. To overcome the loss of samples during testing, the thin film will be coated with conductive polymers such as polyaniline (PANi), which has high conductivity, can increase photoactive ability, and has good corrosion resistance. In this study, the performance of ZnO NRs/PANi against AZO NRs/PANi will be studied by adding aluminium. The ZnO nanorods were synthesized by Hydrothermal method, Aluminium was deposited on ZnO NRs by DC Magnetron Sputtering method, and PANi was synthesized by polymerization method. From the XRD characterization results, it can be concluded that the addition of aluminium to ZnO NRs/PANi causes an increase in crystallinity and peak shift. SEM characterization shows that the addition of Al to ZnO NRs/PANi causes the porosity value to increase. In addition, UV-Vis characterization showed that the addition of Al material to the ZnO NRs/PANi thin film resulted in a wider range of absorbance of the light spectrum. Then, Cyclic Voltammetry test shows that the addition of aluminium increases the efficiency of the photoelectrochemical.

Abstract

The performance of activated carbon (AC)-based supercapacitor electrodes is often limited by poor electrical conductivity, prompting interest in conductive additives such as carbon black (CB). This study explores the transformative potential of CB as a conductive additive in AC-based supercapacitor electrodes and systematically investigates CB mass loadings of 0%, 5%, 10%, 15%, and 20%, using styrene-butadiene rubber (SBR) as the binder. The findings in this study demonstrate that 10% CB is the optimal loading, offering a balanced performance in terms of structure, morphology, and capacitance. X-ray diffraction (XRD) analysis reveals a distinct structural evolution at 10% CB, characterized by the exclusive emergence of a (100) peak at 43° 2θ, which indicates the formation of dense graphene-like layers and enhanced π-π electron delocalization. This promotes the formation of robust conductive networks, reducing electrode resistivity by 72%. Morphological and specific surface area characterization confirms the uniform particle distribution of an ultra-thin electrode AC-10% CB (26.5 μm) with a high surface area of 851.84 m²/g; this maximizes ion-accessible active sites and minimizes diffusion pathways. These combined effects result in a specific capacitance of 61.33 F/g, representing a 12% improvement over the pristine electrode (56.36 F/g) and 89.87% capacitance retention after 50 cycles. These results highlight the importance of optimizing CB loading: Lower concentrations (

Abstract

Separators in supercapacitors have an important role as intermediaries for ions that pass during the charge-discharge process and affect the performance of supercapacitors. Therefore, a comprehensive study is needed related to separator characteristics, including morphology, pore size, diameter, functional group, and electrochemical performance of separator membranes from PAN/PVDF composites. The separator membrane was synthesized using the electrospinning method with thickness variation (2, 4, 6, 8, and 10 layers), followed by supercapacitor fabrication with coin cell device. The resulting membrane was then characterized by Scanning Electron Microscope (SEM) and Fourier Transform Infrared (FTIR). For the result of supercapacitor fabrication with coin cells, Galvanostatic Charge-Discharge (GCD), Cyclic Voltammetry (CV), and Electrochemical Impedance Spectroscopy (EIS) were carried out to determine supercapacitor performance. FTIR results showed that the PAN/PVDF membrane was successfully composites with the addition of new peaks identified as PVDF and PAN at wave numbers 2243.21 and 881 cm-1. The nanofibers formed have diameters ranging from 319.7 to 339.95 nm. The optimum percentage of electrolyte uptake is obtained at membranes that have 6 layers, which is 318.18% and decreases to 173.68% the thickness is 10 layers. In this study, the optimum supercapacitor performance was obtained in the 6 layers variation with a thickness of 75.91 x 103 nm with a gravimetric capacitance value is 53.36 F/g, the capacity retention is 88.96% after being tested for 500 cycles, the largest curve area of CV, and an ionic conductivity value is 54 x 10-5 S/cm.
