The effect of Zr loading in Zr/TiO 2 prepared by pressurized hot water on its surface, morphological and photocatalytic properties
Zr/TiO 2 anatase photocatalysts with 0.5, 1, 2, 5 and 7.5 mol.% Zr were prepared using pressurized hot water crystallization and their photocatalytic activity was explored in acid orange 7 photodegradation. Parent TiO 2 was also prepared and tested. From all tested photocatalysts, 2 mol.% Zr/TiO 2 showed the highest photoactivity, and 7.5 mol.% Zr/TiO 2 showed the lowest photoactivity. The po
