As COVID-19 profoundly affected nations worldwide, there was a significant reduction in gas and electricity consumption, contrasting with the surplus production of oil and gas by companies. This situation has ignited a growing interest in researching alternative green fuels. Electrochemical water-splitting has emerged as a promising avenue for advancing the green hydrogen economy.

For the initial instance, oxygen deficiency-enriched vanadium pentoxide (O─VO@500) thin film electrodes are tuned by the Pulsed Laser Ablation technique. The O─VO@500 thin film electrode shows remarkable electrochemical performances confirming the greater potential window of -0.4 to 0.

The results disclosed that the 5% Co-doped CuBiO has better PEC activity which is ∼3 fold higher than pristine CuBiO. The doping of cobalt in CuBiO improves the interfacial charge transfer at an electrode/electrolyte interface and reduces the recombination rate of photogenerated electron-hole pairs.

To address these issues, sulfur doped-graphitic carbon nitride/bismuth tungstate (S-g-CN/BiWO) heterostructured hybrid material with different wt% of S-g-CN were constructed via an ultrasonic approach. The formation of heterostructure offers well-separated electron-hole pairs, thereby improving the charge transfer process, and boosting water oxidation kinetics on the surface of modified electrodes.

The heterojunction materials have employed in photoelectrochemical (PEC) water splitting. The PEC activity and stability of the materials are promoted by constructing an interface between the visible light active semiconductor photocatalyst and cocatalysts.
