A novel metal organic framework (MOF)-derived porous copper/zinc bimetallic oxide catalyst was developed for the photoreduction of CO₂ to methanol at a very fast rate of 3.71 mmol g_cat⁻¹ h⁻¹. This kind of photocatalyst with high activity, selectivity and a simple preparation catalyst provides promising photocatalyst candidates for reducing CO₂ to methanol.
