The formation of interfacial electric fields using semiconductors/co-catalysts can effectively improve the carrier migration efficiency photocatalytic devices. Herein, an ultrathin 2D/2D/2D black phosphorus/MXene/MBene (denoted as BP/Ti3C2/MoB) ternary heterojunction with enhanced charge transfer is designed dual fields. formed by BP/Ti3C2 and Ti3C2/MoB accelerate photogenerated transfer, change position d-band center Ti atoms, lower energy level antibonding state, enhance adsorption effect H∗ active species, which ultimately leads to significant enhancement activity. results show that optimum visible-light-induced H2 evolution rate BP/Ti3C2/MoB 8,624 μmol g−1 h−1, has a very high factor (∼1,563%) compared pure BP. charge-transfer pathways mechanism are further elucidated some state-of-the-art spectroscopic characterizations theoretical calculations.

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.
