Modulation of charge-transfer behavior via adaptive interface treatment for efficient photoelectrochemical water splitting

Abstract

The integration of transition metal hydroxide (TMH) and semiconductor (SC) is a promising approach for improving photoelectrochemical (PEC) water oxidation. However, the charge recombination occurring at SC/TMH interface is inevitable....

Nanomaterial-based energy conversion and energy storage devices: a comprehensive review

“…Between the photo-electrode and the electrolyte, effective charge transfer is required for both processes. 82 In addition to the energy levels, the shape, defect concentration, and doping degree of the semiconductor material in the PE all affect how well charge carriers are transported. 81 Additionally, a high specific surface area nanomaterial that can make significant contact with the electrolyte is preferred.…”

Engineering the transition metal hydroxide–photoanode interface with a highly crystalline mediator for efficient photoelectrochemical water splitting

“…Photoelectrochemical (PEC) water splitting has emerged as a highly promising and efficient strategy for the direct conversion of solar light into hydrogen energy to tackle global energy demands and environmental challenges. 1–7 In order to realize the practical applications of PEC water splitting, 8–13 it is crucial to design and fabricate semiconductor (SC) photoanodes that possess adequate light absorption capabilities, efficient charge separation, and high surface reactivity. 14,15 Tremendous efforts have been directed toward the investigation of SC photoanodes, such as Fe 2 O 3 , 16–19 TiO 2 , 20 Ta 3 N 5 (ref.…”
