Constructing hierarchical and ultrathin-structured metal sulfides is beneficial for achieving high-efficiency hydrogen evolution catalysts. Herein, ZnIn2S4 (ZIS) hollow nanoflowers (HNFs) composed of ultrathin nanosheets are creatively synthesized via a facile trisodium citrate-mediated stirring-assisted solvothermal method. Experimental results reveal that the synergy effect ethanol, citrate, ...

As an abundant potentially dangerous waste, red mud (RM) requires a straightforward method of resource management. In this paper, RM catalyst loaded with cobalt (Co-RM) was prepared by the coprecipitation for efficient activation persulfate (PS). Its degradation performance and mechanism ofloxacin (OFL) were investigated. The characterization results scanning electron microscopy, X-ray diffract...

Photocatalytic H 2 production from water splitting is an effective method to solve energy crisis and environmental pollution simultaneously. Herein, carbon@CdS composite hollow spheres (C@CdS-HS) are fabricated via a facile hydrothermal using porous carbon (C-HS) as the template. The C@CdS-HS shows excellent photocatalytic -generation rate of 20.9 mmol h ?1 g (apparent quantum efficiency 15.3% ...

Visible light photocatalytic H(2) production from water splitting is of great significance for its potential applications in converting solar energy into chemical energy. In this study, a series of Zn(1-x)Cd(x)S solid solutions with a nanoporous structure were successfully synthesized via a facile template-free method at room temperature. The obtained solid solutions were characterized by X-ray...
