Abstract Efficient photocatalytic reduction of CO 2 to high‐calorific‐value CH 4 , an ideal target product, is a blueprint for C 1 industry relevance and carbon neutrality, but it also faces great challenges. Herein, we demonstrate unprecedented hybrid SiC photocatalysts modified by Fe‐based cocatalyst, which are prepared via facile impregnation‐reduction method, featuring optimized local electronic structure. It exhibits superior carbon‐based products yield 30.0 µmol g −1 h achieves record selectivity up 94.3%, highlights the effectiveness electron‐rich Fe cocatalyst boosting performance selectivity. Specifically, synergistic effects directional migration photogenerated electrons strong π‐back bonding on low‐valence effectively strengthen adsorption activation reactants intermediates in → pathway. This study inspires effective strategy enhancing multielectron capacity semiconductor with low‐cost instead noble metals as cocatalysts.

Selective photocatalytic CO2 methanation provides an attractive avenue to address energy and environmental issues. However, impediments such as the sluggish adsorption activation of H2O molecules, along with unexpected intermediate desorption, greatly restrict activity selectivity methanation. To these issues, we devised a dual-active site catalyst comprising Cu single atoms (SAs) nanoclusters (NCs) supported on defective TiO2 (Cu1+NCs/BT). As result, remarkable CH4 98% yield 19.63 μmol gcat.–1 h–1 can be obtained over as-prepared Cu1+NCs/BT in pure water. Mechanistic studies reveal enhanced performance could ascribed synergistic effect sites, where SAs adsorb activate CO2, while NCs boost dissociation for *H coverage. Additionally, adjacent jointly stabilize *CO reduce barrier protonation, promoting multielectron transfer process.

Abstract Photocatalytic CO 2 reduction to hydrocarbon fuels through solar energy provides a feasible channel for reducing emission and resource depletion. Nevertheless, severe charge recombination high barrier limit the efficiency. Herein, surface amine‐functionalized SnO with oxygen vacancies (A‐Vo‐SnO ) is fabricated achieve visible‐light‐driven photocatalytic reduction. Specifically, amino groups modified onto of catalyst can provide more active sites promote adsorption . Meanwhile, synchronously induced defect level reduces band‐gap expands light‐absorption region from UV light visible light. The modulate electronic structure work as separation centers spatial charges, thus promoting interfacial transfer efficiency providing catalytic sites, evidenced by experimental observation theoretical calculation. As expected, this A‐Vo‐SnO exhibits CH 4 evolution rate 17.27 µmol g −1 h without adding sacrificial agent co‐catalyst, much higher than 5.98 pure This significant inspiration design engineering based on photocatalysts towards conversion.
