By virtue of the systematic effects of S-doping on CeO2 and the ultrathin shell structure of CdS, the CeO2−xSx@CdS nanocomposite exhibits excellent photocatalytic activity under visible-light illumination for both H2 evolution (rate up to 1147.2 μmol g−1 h−1) and RhB degradation (efficiency reached 99.8%) as compared to CeO2, CeO2−xSx, and CdS.

Nitrogen-doped titania with a unique two-level hierarchical structure and visible light photocatalytic activity is reported. Thus, nitrogen-doped titanium oxide microrods decorated with N-doped titanium oxide nanosheets were synthesized by a hydrothermal reaction in NH4OH and postcalcination. During the calcination, the in situ incorporation of nitrogen atoms of ammonium ion into titania lattice was accompanied by the structural evolution from titanate to anatase titania. The morphological and structural evolution was monitored by scanning electron microscopy (SEM), x-ray diffraction (XRD), thermogravimetric analysis/differential thermal analysis (TGA/DTA), Raman, Fourier transform infrared (FTIR), x-ray absorption near edge structure (XANES), x-ray photoelectron spectroscopy (XPS), and adsorption isotherms. The N-doping brought visible light absorption, and the material exhibited high photocatalytic activity in the decomposition of Orange II under visible light irradiation (λ ≥ 400 nm), especially when it was loaded with 1 wt% Pt as a cocatalyst.

Controlled synthesize of Sn-oxides was achieved via a facile hydrothermal method with SnCl2 as precursor. A visible light photocatalytic activity of SnO2 can be induced by doping with Sn2+ or coupling with SnO.
