摘　　要：The promising S-scheme heterojunction photocatalysts are considered as a novel frontier due to their superiority in various solar-driven energy-related applications.Recently,a novel atom-specific tailoring strategy has been introduced on the construction of S-scheme het-erojunction for promoting the electronic transferability.The S-scheme heterojunction is regulated by integrating high-crystalline carbon nitride with Co-doped CeO_(2).Specifically,this atom-specific regulation of S-scheme heterojunction boosts directional electron-driving effect towards functionalized Co sites,benefit-ing for effective photogenerated charge carrier transferability.Moreover,a series of tracking characterizations show that Co-embedded modification promotes CO_(2)photoreduction into hydrogenation steps,resulting in high performance towards CO_(2)-to-CH_(4)photoreduction,which provides new opportunities for the development of multifunctional cooperation in heterogeneous photocatalysis.
