Photocatalytic conversion of carbon dioxide (CO2) to fuel provides an ideal pathway achieving neutrality. One significant hindrance in the reduction CO2 higher energy density multicarbon products (C2+) was difficulty coupling C–C bonds efficiently. Copper (Cu) is considered most suitable metal catalyst for form C2+ reaction (CO2RR), but it encounters challenges such as low product selectivity and slow catalytic efficiency. Herein, we constructed a defect on Cu-doped nitride (Cu–CvN), efficient photocatalytic CO2RR. The optimized (Cu–CvN-550) with shows high activity ethanol, ethanol production rate 122.6 μmol g–1 h–1 93.7%. yield 4.5 times than that Cu–CN-550 without defect. ratio Cu+/Cu0 Cu species changes regularly calcination temperature, which linearly correlated liquid DFT calculations combined experimental results revealed doping promoted activation, followed by enhanced *CO adsorption weakened hydrogenation desorption. Carbon defects lower free greatly accelerate transfer process promoting formation six-membered ring intermediate state, serving intramolecular dimerization. Synergistic thermodynamic kinetic interactions were realized through introduction defects, thereby enhancing performance production.

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.

The production of high-energy-density liquid fuels through the photoconversion CO2 offers a highly efficient method for storing sustainable solar energy future use. Bi4Ti3O12 (BTO) nanorods loaded with Cu–Pd nanoalloys were designed selective photoreduction to ethyl alcohol, using H2O as proton source. A tandem synergistic catalysis mechanism was proposed this process. Initially, *CO intermediates are produced at BTO nanorod, then transfer neighboring Cu atoms, where they convert into alcohol via C–C bond formation on Pd atoms. Adjusting ratio can modify binding strength catalyst surface and reaction kinetics reduction, thus optimizing efficiency selectivity products. With substitution TiO2, CeO2, SiO2 nanorod in similar systems, only CO or CH4 produced, highlighting essential role present photoconversion. Additionally, thermal-assisted photocatalysis also tested lower free barrier *OCCO intermediate, crucial production, enhance charge separation BTO, leading 2.7-fold improvement compared that under light illumination alone. photocatalytic reduction device well area 25 cm × cm, providing potential model large-scale from CO2.
