The production of hydrogen (H2) through photoelectrochemical water splitting (PEC-WS) using renewable energy sources, particularly solar light, has been considered a promising solution for global and environmental challenges. In the field hydrogen-scarce regions, metal oxide semiconductors have extensively researched as photocathodes. For UV-visible light-driven PEC-WS, cupric (CuO) emerged sui...

Carbon-protected BiVO4 photoanode and Cu2O photocathode tandem photoelectrochemical (PEC) system has been explored to reduce surface recombination enhance the stability of photoelectrodes. In addition carbon layer, electrodeposited FeOOH nanolayer drop-casted MoS2 co-catalyst layer on photocathode, respectively improve reaction kinetics. The optimized (Mo-BiVO4/C/FeOOH) (Cu2O/C/MoS2) produces c...

Pulse responses of different materials commonly used as electron sources in photoinjectors have been determined. Thin film photocathodes, such strained GaAs/GaAsP superlattice and K2CsSb, produce fast responses. The emission intensity at time scales comparable with the acceptance accelerators is found to be reasonably low, which an advantage for operation high beam powers. temporal these cathod...
