Manipulated Directional Hydrogen Spillover for Enhanced Photothermal Tandem Ethane Dehydrogenation
Manipulating chemical reaction processes remained clavis aurea, an insurmountable yet rewarding challenge. Ethylene, essential to modern society, could be efficiently produced through tandem photothermal ethane dehydrogenation and reverse water–gas shift (RWGS) reaction system. Manipulating hydrogen spillover could facilitate hydrogen consumption in RWGS reactions and right-shift ethane dehydrogenation reactions. Here, an ErOx/Zn@SAPO-34 catalyst is successfully prepared to construct the tandem catalytic system, whereas the Zn acts as an active site for ethane dehydrogenation and the decorated ErOx functions as a reservoir for surface-active hydrogen to manipulate hydrogen spillover and promote the RWGS reaction on the ErOx surface. Consequently, the solar ethylene yield could surpass the thermal dynamics equilibrium with an ethylene rate of 13.68 mmol g–1 h–1 and a selectivity of ∼97% at 475 °C.
