A one-pot hydrothermal conversion of cellulose with CuO as an oxidant was investigated under alkaline conditions. The results showed that a high yield of organic acids, mainly including acetic acid, glycolic acid, lactic acid, and formic acid, was obtained from cellulose. The highest total yield of the four organic acids reached 43.0% at 325 °C for 1 min. CuO can effectively increase the total yield of organic acids, and Cu2O and Cu 0 can be produced from the proposed process. A reaction pathway of cellulose conversion into organic acids in the presence of CuO was investigated and proposed. The present study is expected to be a link in the development of a new and green method of both cellulose conversion and CuO smelting.
