Fabrication of NiS modified CdS nanorod p–n junction photocatalysts with enhanced visible-light photocatalytic H2-production activity

Abstract: Production of hydrogen from photocatalytic water splitting has become an attractive research area due to the possibility of converting solar energy into green chemical energy. In this study, novel NiS nanoparticle (NP) modified CdS nanorod (NR) p-n junction photocatalysts were prepared by a simple two-step hydrothermal method. Even without the Pt co-catalyst, the as-prepared NiS NP-CdS NR samples exhibited enhanced visible-light photocatalytic activity and good stability for H2-production. The optimal NiS load… Show more

“…Ni-based sulfides, such as NiS and NiS 2 , also serve as efficient cocatalysts for photocatalytic H 2 production by coupling with proper photocatalysts [50][51][52][53][54][55][56][57][58][59][60][61]. As a p-type semiconductor, NiS has been applied in a wide range of areas due to its unique properties.…”

“…Yu and co-workers investigated the intrinsic photoactivity enhancement mechanism of NiS in combination with CdS photocatalysts [52]. By a two-step hydrothermal strategy, the composites consisting of p-type NiS nanoparticles deposited on n-type CdS nanorods were successfully fabricated with many p-n junctions generated at the interface.…”

“…In response to this, materials which can remove the harmful pollutants irreversibly and eliminate them completely have been developed [1][2][3][4][5][6][7][8][9][10]. Heterogeneous photocatalysis is an emerging technique for environmental remediation, where semiconductor materials are used as photocatalysts [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. When organic pollutants are decomposed by heterogeneous catalytic reactions, the pollutant molecules are adsorbed on the surface of the catalysts, where chemical bonds are broken and formed, and eventually small organic molecules or carbonate are released as decomposed products.…”
