TL;DR: The responses of individual ZnO nanowires to UV light demonstrate that the persistent photoconductivity (PPC) state is directly related to the electron-hole separation near the surface and illustrates the intrinsic potential of metal oxide nanowire to develop optoelectronic devices or optochemical sensors with better and new performances.

TL;DR: In this paper, the structural properties of H-TiO2 and their effects on photo-generated charges are comprehensively investigated, and it is shown that the higher ratio of trapped holes (O− centers) and a lower recombination rate induced by the increase of surface defects might be the critical factors for the high activity of s-H- TiO2.

TL;DR: In this article, a hierarchical ITO/Fe2O3/FeTiO5/FeNiOOH multi-layer composites for photoelectrochemical water splitting is presented, and a series of systematic experiments designed to elucidate the mechanism underlying the interfacial coupling effect of the quaternary hematite composite.

TL;DR: In this paper, a detailed analysis of photoelectrochemical (PEC) devices from metal oxide electrodes forming a semiconductor-liquid junction to protected and catalyst-decorated third generation solar cells adapted into photo-electrodes is presented.

TL;DR: In this paper, the photocatalytic conversion of methane into methanol from an aqueous suspension containing mesoporous WO3 was studied, as well as the effect of the addition of electron scavengers (Fe3+, Cu2+, Ag+) and H2O2 species.
