Abstract
The rational regulation of perovskite structures provides an effective strategy for developing efficient catalysts for CO₂ conversion. Herein, a series of La-doped NaTaO₃ perovskites were synthesized via a hydrothermal method and systematically investigated the changes in photothermal CO₂ hydrogenation performance induced by structural evolution. Appropriate La doping effectively modulates the crystal and electronic structures of NaTaO₃, increasing accessible surface active sites and enhancing CO₂ adsorption and activation. Meanwhile, improved charge transfer and electron transport further promote the photothermal conversion process. Based on this, the Na 0.95 La 0.05 TaO 3 exhibits superior photothermal CO₂ hydrogenation performance. This work demonstrates the key role of La-induced structural regulation in enhancing CO₂ hydrogenation and provides insights into the design of efficient perovskite-based photothermal catalysts for sustainable CO₂ utilization.
