Ternary CuO/ZnO/CeO₂ catalysts for methanol synthesis from CO₂ were successfully prepared and modified by electron etching with plasma as the electron source. Results indicate that the plasma decomposition leads to higher specific surface, unique structure, and the formation of copper species with a high dispersion, while enhancing reducibility of Cu particles and promoting the catalyst-support interaction due to the especially low temperature of plasma process. Most interesting, electron bombardment produces more oxygen vacancy on CeO₂, which facilitates to increase interaction between Cu, Zn, and CeO₂. CO₂ molecules are preferably adsorbed on the oxygen vacancies of CeO₂ to generate carbonate species. Furthermore, the study shows that CeO₂ is a highly tunable material, which has great catalytic potential for carbon dioxide due to its unique properties, such as rich oxygen vacancy and metal−support interaction, especially under plasma conditions. Surprisingly, Catalytic evaluation revealed that CuO/ZnO/CeO₂ by plasma exhibited a remarkable space-time yield of 162.7 g _methanol·kg^–1 _cat·h^–1 (1.5 times of that of conventional calcined catalyst) at 260 °C. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd.

富氧空位 Cu/ZnO/CeO2 的合成用于 CO2 加氢制甲醇

以等离子体为电子源，通过电子刻蚀成功制备和修饰了用于CO ₂合成甲醇的三元CuO/ZnO/CeO ₂催化剂。结果表明，等离子体分解导致更高的比表面、独特的结构和具有高分散性的铜物种的形成，同时由于等离子体过程的温度特别低，提高了Cu颗粒的还原性并促进了催化剂-载体的相互作用。_{最有趣的是，电子轰击在 CeO 2}上产生更多的氧空位，这有利于增加 Cu、Zn 和 CeO ₂之间的相互作用。CO ₂分子优选吸附在CeO _{2的氧空位上}生成碳酸盐物种。此外，该研究表明，CeO ₂是一种高度可调的材料，由于其独特的性质，例如丰富的氧空位和金属-载体相互作用，特别是在等离子体条件下，它对二氧化碳具有巨大的催化潜力。令人惊讶的是，催化评估表明，等离子体的CuO/ZnO/CeO _{2在260 °C 下表现出162.7 g甲醇}·kg ^–1 _cat ·h ^–1的显着时空产率（是传统煅烧催化剂的1.5 倍）。© 2021 化学工业协会和 John Wiley & Sons, Ltd.
