Abstract Currently, the concentration of carbon dioxide (CO 2 ) has exceeded 400 ppm in atmosphere. Thus, there is an urgent need to explore CO reduction and utilization technologies. Photocatalytic technology can convert valuable hydrocarbons (CH 4 , CH 3 OH, C H 5 etc.), realizing conversion solar energy chemical as well solving problems fossil fuel shortage global warming. Graphitic nitride (g‐C N ), a two‐dimensional nonmetallic semiconductor material, shows great potential field photoreduction due its moderate bandgap, easy synthesis method, low cost, visible light response properties. This review elaborates research progress g‐C ‐based photocatalysts for photocatalytic reduction. The modification strategies (e.g., morphology engineering, elemental doping, crystallinity modulation, cocatalyst modification, constructing heterojunction) application have been discussed detail. Finally, challenges development prospects materials are presented.

Photothermocatalytic dry reforming of methane (DRM) can convert CH 4 and CO 2 into syngas, offering an effective approach to reducing greenhouse gas emissions. However, photothermocatalytic DRM reaction generally needs a high light intensity surpassing 192 kW m −2 attain light‐fuel conversion. Also, catalysts applied are liable inactivation due carbon deposition. Herein, nanocomposite Ni nanoparticles supported on Ni‐ Y‐doped Al O 3 (Ni/Ni‐Y ‐Al ) is prepared. It achieves H production rates with light‐to‐fuel efficiency (29.2%) at lower (80.1 ). Meanwhile, it sustains excellent durability accomplishes 37‐fold reduction in deposition rate compared Ni/Al . The substantially enhanced catalytic activity resistance Ni/Ni‐Y correlated accelerating species (C*) oxidation (the rate‐determining steps DRM). This acceleration derives from the synergetic effect carbonate resulting Y doping, which participate C* via two separate pathways. When light, further facilitates oxidation. Simultaneously, immensely reduces activation energy, activates NiO bonds interface region, expedites between interface, enhancing resistance.

Abstract Photothermocatalytic dry reforming of methane (DRM) offers a promising strategy for converting solar energy into fuel. However, the high light intensity required fuel production rates and thermodynamically more favorable coking side reactions limit this strategy. Herein, nanocomposite La‐doped Al 2 O 3 supporting Ru nanoparticles (NPs) (Ru/La‐Al ) is synthesized. At relatively low (80.2 kW m −2 ), Ru/La‐Al obtains CO H per gram ( r Ru, H2 , 8410.19 7181.94 mmol g −1 min with light‐to‐fuel efficiency η 26.6%), completely prohibits coking. In striking contrast, reference catalyst without La doping (Ru/Al exhibits lower produces large amounts coke. The improved photothermocatalytic performance stems from fact that reactive oxygen species carbonate are involved in oxidation carbon (rate‐determining steps DRM) through two different reaction pathways, which significantly increases catalytic activity prevents polymerizing Additionally, not only enhances DRM on NPs between but also promotes dissociation CH 4 desorption improves product selectivity .
