Abstract Photocatalytic CO 2 reduction into high‐value C 2+ products such as H 6 is of great importance but challenging due to their multi‐electron steps and high energy barrier C─C coupling. Moreover, improving its solar‐to‐chemical (STC) conversion efficiency in pure water beyond the current 1% empirical value also a significant challenge. Herein, graphite carbon nitride (g‐C 3 N 4 ) nanosheets with controllable (C) doping nitrogen (N) vacancies (PCCN‐x) are designed through biochar‐tailored protocol for efficiently selectively photo‐converting . The optimal PCCN‐10 photocatalyst enables achievement an exceptional activity 99.14 µmol g −1 h selectivity 80.33% over 20 water. A record STC ≈1.13% solar fuel production from O vapor achieved without any other inputs. Outdoor tests demonstrated impressive ‐to‐C photo‐conversion rate 43.17 water, stable 50 period. Critically, experimental theoretical calculations further confirm pivotal role bridged sites activating molecules promoting formation coupling intermediate ( * OCCO), which very beneficial performance this work photocatalytic fuels paves way large‐scale broader sustainable applications.

Carbon quantum dots (CQDs) are discrete, quasi-spherical carbon nanoparticles with sizes below 10 nm. The properties of CQDs can be further enhanced by doping elements such as nitrogen, phosphorous, sulphur, and boron or co-doping heteroatoms nitrogen-phosphorous, nitrogen-sulphur, nitrogen-boron. These excellent utilized to enhance the photocatalytic performance semiconductors. Therefore, in this review, we summarize different types bare CQD-scaffolded semiconductors, both doped co-doped, used for hydrogen production. Moreover, detailed mechanism CQD/semiconductor-based production is reviewed. Recent progress design development CQD-based photocatalysts, along challenges involved, comprehensively
