dc.description.abstract | Photocatalytic water splitting by semiconductor nanostructures is a challenging chemical process for harnessing abundant solar energy and obtaining clean H-2 fuel. To this end, photocatalysts that comprise efficient light-harvesting semiconductor nanostructures and noble metal-free robust co-catalysts have attracted considerable attention. In this study, we designed a noble metal-free nanohybrid consisting of CdS nanorods (NRs) as photoabsorbers and CoSe2 nanocages as co-catalysts. Benefiting from suitable band edge potentials, abundant catalytically active sites, large surface area, and efficient photoexcited charge carrier transfer, the fabricated nanohybrid exhibited a remarkable photocatalytic H-2 evolution performance (82.5 mmol h(-1) g(-1)), which is approximately 37.5 times higher than that of bare CdS NRs. Moreover, the observed H-2 evolution rate was even higher than those of even noble metal Pt-anchored CdS NR composites. Furthermore, the fabricated nanohybrid exhibited prominent recycling stability (50 h) under solar light irradiation. The key role of the co-catalyst, the effects of the catalyst dosage and scavenger concentration, and the origin of the photocatalytic H-2 production were comprehensively investigated. We believe that this design is the prospective path toward the development of three-dimensional hollow-type noble metal-free nanostructures for enhancing H-2 production. | - |
