Abstract

CO2 methanation has gained traction for its potential in renewable energy storage, though the high cost of renewable hydrogen production remains a significant barrier to implementation. Herein we present the Ru‐Fe@NCNT catalyst, consisting of ruthenium and iron nanoparticles on nitrogen‐doped carbon nanotubes, as a highly selective, hydrogen efficient, iron‐driven alternative to typical nickel and ruthenium catalysts used for CO and CO2 methanation. Ru‐Fe@NCNTs offer competitive CO2 conversion, improved methane selectivity, 26% higher hydrogen utilisation and an up to 80% reduction in ruthenium loading versus similar literature and commercial catalysts. It is proposed that this desirable CO2 methanation performance is a result of effective cooperation between the iron‐catalysed reverse water gas shift and methane‐selective Fischer‐Tropsch, and ruthenium‐catalysed CO methanation reactions.
