Surface passivation engineering is an imperative way to improve photoelectrode performance for photoelectrochemical (PEC) water splitting. To the best of our knowledge, it has never been systematically reviewed in a feature article. In this review, we summarize various materials and their preparation, characterizations by PEC measurements some related spectral technologies. We highlight feature...

Graphdiyne (GDY) is an emerging 2D carbon material that exhibits unusual structures and properties. Therefore, growing heterogeneous materials on the surface of GDY very attractive to achieve efficient energy utilization. Here, a simple method for controllable synthesis ultrathin charge-transfer complexes (CTs) nickel with terephthalic acid nanosheets reported. This catalyst shows record-high o...

Solar water splitting is a promising technique for harvesting solar energy and converting abundant sunlight into storable hydrogen fuel. The cuprous oxide photocathode, one of the best-performing photocathodes, possesses theoretical photocurrent density up to 14.7 mA cm ?2 photovoltage as large 1.6 V, making it possible convert in low-cost way. Herein, comprehensive review improving performance...

Abstract The traditional view of the conductivity electrolytes is based on mobility ions in an electric field. A new concept water introduces electron–hole mechanism known from semiconductor theory. electrolyte hydrogen bond network imitate structure a doped silicon lattice. source current carriers electrode reaction generating H + and OH − ions. continuity flow provided through mechanism, move...
