Current progress in developing metal oxide nanoarrays-based photoanodes for photoelectrochemical water splitting

“…In most cases, Ni-, Fe-and Co-based electrocatalysts have been widely used in electro-water splitting owing to their high catalytic activity, chemical stability, and low toxicity. There are various methods to deposit electrocatalysts onto metal oxide array photoelecrodes, including HT/ST, ED, CBD, dropcasting/spin-coating [258][259][260][261][262]. Typically, Feng et al [261] reported that Ni(OH) 2 can be decorated on the surface of H-ZnO nanorods by a CBD method.…”

Anti-photocorrosive photoanode with RGO/PdS as hole extraction layer

“…The other is to accelerate hole transfer and subsequent redox reactions with electrolytes to a level kinetically competitive to the photocorrosion process. The most common strategy in this respect is to introduce hetero/homojunctions for hole transfer [23,25,26], cocatalysts for hole-involved reactions [27][28][29], and combinations thereof, giving rise to some encouraging results. Whereas, efforts in improving the solar conversion efficiency and anti-photocorrosion capability of CdSe/CdTebased photoanodes remains unsatisfying, due to the absence of suitable hole extraction layers (HELs).…”
