| abstract |
The invention provides a cuprous oxide-copper oxide/carbon nitride composite oxide with adjustable oxygen vacancy, a preparation method thereof and an application thereof, the preparation method comprises the following steps: using basic copper carbonate as a copper source, glucose as a reducing agent, g ‐C 3 N 4 is a composite carrier, and a Cu 2 O‐CuO/g‐C 3 N 4 double-valent copper oxide composite oxide is prepared by a solid-solid-liquid three-phase reduction synthesis method; The ratio of copper carbonate to glucose and g-C 3 N 4 achieve oxygen vacancy modulation of the complex oxide. Compared with the prior art, the invention has mild reaction conditions, good controllability and repeatability, and the operation process is green and environmentally friendly. The process of the invention is simple and controllable, no multi-step operation is required; no pollution, zero discharge; mild synthesis conditions and low production cost. |
