Synthesis of Cu2O micro/nanocrystals for catalytic combustion of high-concentration CO: The crucial role of glucose

Pandong Ma et al.

Summary: Cubic Cu2O micro/nanocrystals were successfully synthesized by liquid-phase reduction using copper salts and reducing agents. The catalysts' activity was evaluated through CO-TPO, with Cu2O-Cl-GLU showing the highest catalytic activity. The unique structure of Cu2O-Cl-GLU with high exposure rate and coordination unsaturation improves the ability to activate gaseous O2 and facilitates the catalytic activity.

Structure sensitivity of CuO in CO oxidation over CeO2-CuO/Cu2O catalysts

Zhenhua Zhang et al.

Summary: By studying the CO oxidation catalyzed by CeO2-CuO/Cu2O nanocomposites with different CuO structures, it was found that the CuO-CeO2 interfaces in the CeO2-CuO/c-Cu2O (cubes) nanocomposites exhibit higher intrinsic activity, indicating that the active oxygen species originates from CuO. An active 13.2% CeO2-CuO/c-Cu2O(s) catalyst for CO oxidation was achieved on fine Cu2O cubes, possessing a high density of active sites.

Evolution behavior and active oxygen quantification of reaction mechanism on cube Cu2O for CO self-sustained catalytic combustion and chemical-looping combustion

Running Kang et al.

Summary: This study compares the evolution behavior and reaction mechanisms of copper catalysts in catalytic combustion and chemical looping combustion. The results show that catalytic combustion has higher activity and stability compared to chemical looping combustion. Different active oxygen species and reaction pathways were proposed, and the contribution degrees of Mars-van-Krevelen and Langmuir-Hinshelwood mechanisms were determined.

Transient behavior and reaction mechanism of CO catalytic ignition over a CuO-CeO2 mixed oxide

Running Kang et al.

Summary: This study investigates the activity-controlling factors during CO catalytic ignition over a CuO-CeO2 catalyst. The results show that CuO has higher activity for CO combustion compared to CuO-CeO2, with temperature and oxygen playing key roles in the process. Various characterization techniques are used to understand the adsorption and reaction mechanisms of CO on the surface, as well as the reaction process post-ignition.
