Abstract. The effect of initial concentration of pollutant on the photocatalytic activity of photocatalysts based on calcium bismuthate is studied. This effect is investigated for photocatalysts of different composition and structure. The derived dependences allow to determine the optimal pollutant concentrations, as well as the photocatalyst composition and structure most promising for further practical use.
Keywords: visible light active photocatalysts, calcium bismuthates, bismuth oxide, phenol photo-catalytic degradation
