product of isopropanol, respectively. NaTaO3nanocubes loaded with 2 wt % CuO and synthesized in 2 mol/L NaOH solution showed the best activity. The methanol and acetone yields were 137.48 μmol/(g·h) and 335.93 μmol/(g·h), respectively, after 6 h of irradiation. Such high activity could be attributed to
the good crystallinity, morphology and proper amount of CuO loading, which functioned as reductive sites for selective formation of methanol. The reaction mechanism was also proposed and explained by band theory.

In this paper, we report the photocatalytic reduction of CO2 to methanol using CuO-loaded NaTaO3 catalysts. NaTaO3nanocubes were synthesized via a hydrothermal method using Ta2O5 and NaOH. CuO was loaded onto the surface of NaTaO3 by impregnation, where CuO acts as a
