RuCo/ZrO₂ Tandem Catalysts with Photothermal Confinement Effect for Enhanced CO₂ Methanation.

ABSTRACT: Photothermal CO₂ methanation reaction represents a promising strategy for addressing CO₂-related environmental issues. The presence of efficient tandem catalytic sites with a localized high-temperature is an effective pathway to enhance the performance of CO₂ methanation. Here the bimetallic RuCo nanoparticles anchored on ZrO₂ fiber cotton (RuCo/ZrO₂) as a photothermal catalyst for CO₂ methanation are prepared. A significant photothermal CO₂ methanation performance with optimal CH₄ selectivity (99%) and rate (169.93 mmol g_cat ^-1 h^-1) is achieved. The photothermal energy of the RuCo bimetallic nanoparticles, confined by the infrared insulation and low thermal conductivity
