Studies on the hydrogen h2 photocatalytic performance of au and C3N4 incorporated various metal oxides based nanocomposites for hydrogen storage applications

Abstract

newline There has been a lot of buzz about semiconductor photocatalytic hydrogen generation since it is the most feasible way to turn solar energy into green chemical electricity. As a result, developing a photocatalytic technology that efficiently converts solar energy and triggered by visible light is of the utmost importance. However, photocatalysts poor quantitative output and restricted capacity to capture visible light are obstacles to their use in commercial contexts. In contrast to photocatalysts composed of one kind of semiconductor, those with many components may be used to control the band structure and increase the electron-hole separation rate. The capacity of photo-induced carriers to undertake redox responses is diminished when conventional two-semiconductor hetero junctions are used. As a result, attaining a substantial oxido-reduction potential for H 2 evolution is not possible. Luckily, for all those problems, numerous researchers have found employing the noble metals as electronic transmission agents to build solid state Semiconductor Metal Semiconductor (S-M-S) Z-scheme hetero structures may solve them. A certain hetero structures may be described as follows: g-C 3 g-C 3 N 4 N 4 /Au/CdS g-C /Au/BiOCl.
