Photodegradation of organic dyes via competitive direct reduction/indirect oxidation on InSnS2 under visible light

Preparation of sputter-deposited Cu-doped BiVO4 nanoporous thin films comprised of amorphous/crystalline heterostructure as enhanced visible-light photocatalyst

“…This could mean that a significant part of the electrons separately participated in the direct photoreduction of RhB. This phenomenon has been reported in the literature [59] and also observed by our team [10] regarding the photocatalytic degradation of RhB by pristine BiVO 4 thin films. The contribution of electrons in pristine BiVO 4 is lower than that implied in the Cu-doped BiVO 4 film, probably resulting from a direct effect of Cu doping on the electron charge carrier concentration.…”
