Visible Light-Driven Photocatalysis of Al-Doped SrTiO: Experimental and DFT Study.

Environmental problems associated with water pollution caused by organic dyes have raised serious concerns. In this context, photocatalytic processes have proven to be promising and environmentally friendly methods for water purification utilising abundant solar energy. In this study, a SrTiO-based photocatalyst was modified by doping with Al ions and the deposition of dual co-catalysts (Rh/CrO and CoOOH) to enhance the photocatalytic decomposition efficiency of methylene blue (MB).
