Copper tungstate (CuWO4) has recently emerged as a potential high-performing photoanode for photoelectrochemical water splitting due to its suitable optical properties and high chemical resistance. Here, we present simple deposition method the fabrication of CuWO4 photoanodes with record performance, discuss many outstanding challenges this material. First, show how presence within reaction mixture is vital achieving more effective complexation both copper tungsten species, subsequently...
Photoelectrolysis of water using solar energy into storable and environment-friendly chemical fuel in the form hydrogen provides a potential solution to address environmental concerns fulfill future requirements sustainable manner. Achieving efficient spontaneous evolution light as only input is highly desirable but difficult target. In this work, we report perovskite cell integrated CdS-based photoanode for unbiased photoelectrochemical evolution. An tandem device consisting mesoporous...
In this work, we report on defects generation in TiO2 inverse opal (IO) nanostructures by electrochemical reduction order to increase photocatalytic activity and improve photoelectrochemical (PEC) water splitting performance. Macroporous structures, such as opals, have attracted a lot of attention for energy-related applications because their large surface area, interconnected pores, ability enhance light-matter interaction. Photocurrent density electrochemically reduced TiO2-IO increased...
The research interest in photoelectrochemical (PEC) water splitting is ever growing due to its potential contribute towards clean and portable energy. However, the lack of low energy band gap materials with high photocorrosion resistance primary setback inhibiting this technology from commercialisation. ternary alloy InGaN shows promise meet photoelectrode material requirements chemical stability tunability. can be modulated UV IR regions by adjusting In concentration so as absorb maximum...
Cadmium sulfide (CdS) is a unique semiconducting material for solar hydrogen generation applications with tunable, narrow bandgap that straddles water redox potentials. However, its potential towards efficient has not yet been realized due to low photon-to-current conversions, high charge carrier recombination and the lack of controlled preparation methods. In this work, we demonstrate highly CdS/TiO2 heterostructured photoelectrode using atomic layer deposition solution ion transfer...
Three-dimensional (3D) ordered macroporous (such as inverse opal) heterostructure materials are attractive for photocatalysis because of their interconnected pores, high surface area, light-harvesting properties, and favorable charge-transfer properties. In this work, we report the preparation TiO2–TaOxNy opals using atomic layer deposition investigate photoelectrochemical performance. Through ultraviolet photoelectron spectroscopy analyses band alignment TiO2 TaOxNy, confirm that a type II...
