- W4383602103 abstract "Solar-driven hydrogen production via water splitting is regarded as the most practical and efficient method of production of green energy. Hydrogen is a suitable renewable energy, which is important for environmental sustainability, renewable energy is considered to be the most environmentally friendly, and cost-effective. However, the efficiency of producing hydrogen via photocatalysis remains low. The efficiency of hydrogen production through photocatalysis can be enhanced by preparing a suitable and efficient photocatalyst. For this purpose, the band gap of metal oxides needs to align to reduce it for the photocatalytic process. To improve the efficiency of hydrogen production the band gap of metal oxides (CdTe, WO3, CuO, SnO2, and MoO3) is aligned to reduce it, for the photocatalytic process in terms of multilayer heterostructure thin films. In this particular study, a physical vapor deposition technique is used to deposit metal oxides (CdTe, WO3, CuO, SnO2, and MoO3) on the ITO substrate. The photo-electrochemical properties of multilayers showed quite better results as compared to individual thin films. The multilayer heterostructure thin film of metal oxides (CdTe, WO3, CuO, SnO2, and MoO3) is carried out through XRD, FTIR, UV, transmittance, SEM, and LSV under dark conditions and light conditions. UV of thin film heterostructure reveals the absorbance of solar spectra and the Tauc plot via UV spectroscopy confirmed the reduction of the band gap of metal oxides. SEM study confirmed the grain size of the thin film and the surface plot of the films for the absorption of solar spectra for the generation of hydrogen. LSV showed better photocurrent response under light conditions as compared to dark conditions. The EIS analysis confirmed the charge transfer at the electrode-electrolyte interface for multilayer heterostructure is much better than that of individual metal oxide thin film. The decrease of the EIS curve confirmed the enhancement of photocurrent. The hydrogen production rate per hour was also measured." @default.
