Effective charge separation in photoelectrochemical water splitting: a review from advanced evaluation methods to materials design

“…[149][150][151][152] As the oxidation process proceeds, the photoanode undergoes oxidation and dehydrogenatively reforms the chemicals, turning them into value-added chemicals. [153][154][155][156] 3.4 Light-induced modulation An inverse proportionality exists between the current and the effective mass of the material. The effective mass in a semiconductor varies in terms of charge carriers (holes or electrons), crystallographic directions, and electric eld intensity (applying bias).…”

Ni/WS2/WC Composite Nanosheets as an Efficient Catalyst for Photoelectrochemical Hydrogen Peroxide Sensing and Hydrogen Evolution

“…Up to now, various PEC materials, such as TiO 2 , ZnO, NiO, CuO and Cu 2 O, have been explored [ 14 , 15 , 16 , 17 ]. Among these PEC nanomaterials, W-based and Mo-based electrocatalysts such as carbides, nitrides, oxides, sulfides and their heterostructures have attracted much interest because of their unique electronic structure and optical properties [ 18 , 19 , 20 , 21 , 22 , 23 ]. For instance, Wang et al reported vertically aligned W(Mo)S 2 /N-W(Mo)C nanosheets to be used as the light-assisted electrocatalysis for HER [ 19 ].…”

“…For instance, Wang et al reported vertically aligned W(Mo)S 2 /N-W(Mo)C nanosheets to be used as the light-assisted electrocatalysis for HER [ 19 ]. A novel WO 3 /Mo:BiVO 4 heterojunction photoanode has also been constructed for PEC H 2 O 2 sensing [ 22 ]. In addition, a hierarchical Mo 2 C@MoS 2 has been developed for sensitive H 2 O 2 sensing, superior to most of the non-enzymatic electrocatalysts [ 23 ].…”
