Effects of incorporation of Ag into a kesterite CuZnSnS thin film on its photoelectrochemical properties for water reduction.

Kesterite CuZnSnS (CZTS) thin films in which the Cu site was partially replaced with Ag were prepared by spray deposition on an Mo-coated glass substrate. Successful replacement of Cu components in the CZTS lattice with Ag up to an Ag/(Cu + Ag) ratio of 0.20 was achieved.

Effects of Zirconium Doping Into a Monoclinic Scheelite BiVO Crystal on Its Structural, Photocatalytic, and Photoelectrochemical Properties.

Effects of zirconium (Zr) doping into BiVO powder on its structural properties and photocatalytic activity for O evolution were examined. The formation of BiVO powder crystallized in a monoclinic scheelite structure (-BiVO) was achieved when the sample was doped with a relatively small amount of Zr. The photocatalytic activity of Zr-doped -BiVO powder was much higher than that of non-doped -BiVO.
