TL;DR: In this article, a scheme for the mechanism of hydrosulfide ions catalytic oxidation was proposed, and a chain-radical reaction initiated on the surface of colloidal CuS nanoparticles and propagating further in the bulk of a solution.

TL;DR: The characteristics of photocatalytic systems based on nanostructural semiconductors, characterized by quantum size effects, are discussed in this article, where an analysis is made of the consequences of exciton quantum confinement in the volume that are significant for photocatalysis.

TL;DR: In this article, the appearance of quantum size effects in ultradisperse semiconductors, their quantitative analysis, and their effect on the absorption of light and on the photophysical (vibrational relaxation of photogenerated hot charge carriers, band-band and defect luminescence) and certain primary photochemical processes (the accumulation of excess negative charge by the semiconductor nanoparticles, interphase electron transfer, etc.) are discussed.

TL;DR: In this article, a general description of the advances and planned developments in the creation of photocatalytic converters of solar energy is given, and possible ways of improving the photocatalyst systems for the production of hydrogen with metal-sulfide and other types of semiconductors are analyzed.
