Abstract
A series of Cr3+doped porous CdIn2S4photocatalysts with good optical property were synthesized via a facile hydrothermal process using sodium dodecyl sulfate (SDS) as template. The above-prepared photocatalysts were characterized by XRD, field emission scanning electron microscopy (FESEM), UV-Vis diffusive reflectance spectroscopy (DRS) and XPS. The influences of Cr3+doping concentration on the morphology and photocatalytic activity of CdIn2S4photocatalysts were investigated. The results demonstrated that the presence of Cr3+doping in the CdIn2S4photocatalyst had significantly influence on the crystal structure, micro-morphology, e--h+recombination and photocatalytic activity. The photocatalytic hydrogen evolution of CdIn2S4was enhanced by doping, and the highest rate of hydrogen evolution of 758.8 μmol/(h·g) over Cr3+(0.5%)-CdIn2S4was observed.
