Title
High-stable CuPd–Cu2O/Ti-powder catalyst for low-temperature gas-phase selective oxidation of alcohols
Abstract

•CuPd–Cu2O/Ti-powder is prepared using a simple impregnation method.•CuPd–Cu2O/Ti-powder exhibits excellent activity and stability after activation.•CuPd(alloy)–Cu2O formed during the reaction contributes to the activity and stability.

The oxidation of alcohols to carbonyl compounds in gas-phase is of great importance in organic chemistry and industrial process. Herein, the catalyst CuPd–Cu2O/Ti-powder is prepared by depositing Cu(NO3)2 and Pd(NO3)2 on Ti powder support followed by in-situ activation in reaction stream, which delivers high-performance for the gas-phase oxidation of alcohols. Compared with Cu/Ti-powder and Pd/Ti-powder, CuPd–Cu2O/Ti-powder exhibits higher stability and activity in alcohol oxidation reaction. The catalyst is characterized by XRD, XPS, TEM and ICP. The results indicate that CuPd(alloy)–Cu2O formed during the reaction contributes to the high activity and stability.
