Enhancing selectivity for semi-hydrogenation of Ni by periodic isolation in the MM′X structure

Abstract

Semi-hydrogenation of acetylene is of great importance but presents a significant challenge in maintaining high ethylene selectivity at complete conversion of acetylene. Herein, we report that the over-hydrogenation on Ni...

Exploration of the active sites on a Rh–In2O3 catalyst for the semi-hydrogenation of acetylene: a theoretical study

“…Currently, noble metal catalysts have been successfully applied in the industry. 3,[6][7][8][9][10] Some transition metal oxides have shown the potential for selective alkyne hydrogenation, which originates from the activation of H 2 and alkyne species. 11,12 Intense efforts are being made towards the development of novel catalysts for the selective hydrogenation of acetylene to ethylene.…”
