Herein, we employ the steam hydrogenation capability of proton conductors to achieve collateral CO2 methanation over the Ni/BaZr0.85Y0.15O3- catalyst, which is shown to outperform its conventional Ni/Al2O3 counterpart in terms of CH4 yield (8% higher) and long-term stability (3% higher for 150 h) at 400 degrees C while exhibiting a CH4 selectivity above 98%. Moreover, infrared and X-ray photoelectron spectroscopy analyses reveal the appearance of distinct mobile proton-related OH bands during the methanation reaction.
