Construction of Low-Cost Z-Scheme Heterojunction CuO/PCN-250 Photocatalysts Simultaneously for the Enhanced Photoreduction of CO to Alcohols and Photooxidation of Water.

Solar-driven high-efficiency conversion of CO with water vapor into high-value-added alcohols is a promising approach for reducing CO emissions and achieving carbon neutrality. However, the rapid recombination of photogenerated carriers and low CO adsorption capacity of photocatalysts are usually the factors that limit their applicability. Herein, a series of low-cost Z-scheme heterostructures CuO/PCN-250- are constructed by growth of ultrasmall CuO nanoparticles on PCN-250.
