The photocatalysts have been prepared by an impregnation method of Nb2O5 and Ta2O5 in the aqueous solution of sodium hydroxide and then the calcination at the temperature range of 450 - 800°C. In this report, we present the study showing that of the catalysts explored, the highest photocatalytic activity was shown in a sample obtained at the temperature of 450°C and containing NaTaO3 as a main phase.</abstract>
