Abstract

Nanostructured semiconductor films of SnO 2, TiO 2 and SnO 2 /TiO 2 have been employed for electrochemically assisted photocatalytic degradation of a textile azo dye naphthol blue black (NBB). The degradation rate is significantly higher for SnO 2 /TiO 2 composite films than SnO 2 and TiO 2 films al...
