Abstract

For the first time, a novel iron-promoted Rh catalyst is developed to produce CO-free H 2 through steam reforming of ethanol at low temperatures, between 623 and 673 K. The iron oxides in the vicinity of Rh sites reduce the CO adsorption on Rh sites and transfer the adsorbed CO from Rh to COO-formate species on Fe x O y for the subsequent water–gas shift reaction, resulting in a high H 2 yield, extremely low CO selectivity, and a long Rh life span.
