Effect of the Zn/Ce ratio in Cu/ZnO–CeO<sub>2</sub> catalysts on CO<sub>2</sub> hydrogenation for methanol synthesis
Shuai Chang, Wei Na, Jiaqi Zhang, Lina Lin, Wengui Gao
Abstract
The addition of appropriate amounts of CeO 2 to the Cu/ZnO–CeO 2 catalyst can reduce the size of the Cu particles, increase the dispersion of Cu, reduce the reduction temperature and increase the concentration of basic sites and oxygen vacancies on the catalyst.
