Mixed valence copper oxide composites derived from metal-organic frameworks for efficient visible light fuel denitrification.

ABSTRACT: The construction of heterojunctions has been used to optimize photocatalyst fuel denitrification. In this work, HKUST-1(Cu) was used as a sacrificial template to synthesize a composite material Cu_xO (CuO/Cu₂O) that retains the original MOF framework for photocatalytic fuel denitrification by calcination at different temperatures. By adjusting the temperature, the content of CuO/Cu₂O can be changed to control the performance and structure of Cu_xO-T effectively. The results show that Cu_xO-300 has the best photocatalytic performance, and its denitrification rate reaches 81% after 4 hours of visible light (≥420 nm) irradiation. Through the experimental analysis of pyridine's infrared and XPS spectra, we found th
