Earlier, we reported the photocatalytic behaviour of mixed metal oxides of zinc and tin (MZOTO) and concluded that the composition prepared in the ratio 1:0.5 displays excellent results. Present study details about the formulation of alkyd resin based coating using MZOTO as the pigment in suitable proportion; the contents were homogeneously mixed by high energy ball milling technique. On exposing the coated specimen contaminated by artificial pollutant like crystal violet to sunlight, the pollutant was bleached within 4 h showing its excellent self-cleaning property. Thus the prepared coating provides a new vision to next generation self-cleaning coating to degrade organic pollutants.
