Laser‐driven Plasma Synthesis of CeO 2 ‐bridged Ni Nanoparticles for Efficient and Stable Photothermal CO 2 Methanation

ABSTRACT Photothermal catalytic CO 2 methanation provides a promising route toward realizing carbon recycling. However, conventional supported Ni‐based photothermal catalysts are limited by inadequate CO 2 activation capability and severe sintering of Ni nanoparticles at high temperatures. Here, a bead‐like CeO 2 ‐bridged Ni nanoparticle catalyst (Ni‐CeO 2 ‐Ni) is constructed via a laser‐driven plasma synthesis strategy, in which Ni nanoparticles are bridged by CeO 2 layers to form a cohesive bo
