Revealing the promoting effect of Zn on Ni-based CO<sub>2</sub>hydrogenation catalysts
Liang Shen, Wenhao Zhang, Yifei Feng, Jing Xu, Minghui Zhu
Abstract
Zn preferentially forms an alloy with Ni and at higher loadings is present as ZnO x . Ni–Zn alloy hinders further hydrogenation of *CO and Ni–ZnO x interface changes the CO 2 activation mechanism to a redox pathway.
