Influence of Cu doping on the visible-light-induced photocatalytic activity of InVO<inf>4</inf>
© The Royal Society of Chemistry. The photocatalytic degradation of methylene blue (MB) in the presence of pure InVO 4 or a 0.5-5.0 mol% Cu-doped InVO 4 composite under visible light irradiation (λ ≥ 400 nm) was studied in this research. The structural and photophysical properties of the as-prepared...
