Collateral hydrogenation over proton-conducting Ni/BaZr(0.85)Y(0.15)O(3−δ) catalysts for promoting CO(2) methanation

Despite the importance of CO(2) methanation for eco-friendly carbon-neutral fuel recycling, the current technologies, relying on catalytic hydrogenation over metal-based catalysts, face technological and economical limitations. Herein, we employ the steam hydrogenation capability of proton conductor...

description Despite the importance of CO(2) methanation for eco-friendly carbon-neutral fuel recycling, the current technologies, relying on catalytic hydrogenation over metal-based catalysts, face technological and economical limitations. Herein, we employ the steam hydrogenation capability of proton conductors to achieve collateral CO(2) methanation over the Ni/BaZr(0.85)Y(0.15)O(3−δ) catalyst, which is shown to outperform its conventional Ni/Al(2)O(3) counterpart in terms of CH(4) yield (8% higher) and long-term stability (3% higher for 150 h) at 400 °C while exhibiting a CH(4) 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.
