Abstract

AbstractThe photocatalytic conversion of benzylamine into imine is promising for industrial production and environmental protection. To develop photocatalysts with desirable compositions and microstructures is key to achieve high activity and selectivity. Here we propose the immobilization of Bi2O2CO3 on g‐C3N4 for the photocatalytic conversion of benzylamine. The Bi2O2CO3/g‐C3N4 catalyst possesses improved light absorption capacity, electron transmission rate and reduced electron‐hole recombination than pure Bi2O2CO3. It can efficiently catalyze benzylamine coupling reaction under mild conditions, i. e., at room temperature, with air as oxidant and no additional oxidant involved. The maximum turnover frequency value of N‐benzylbenzaldimine reaches 1555.3 μmol g−1 h−1 under this condition. The Bi2O2CO3/g‐C3N4 catalyst has potential in other photocatalytic reactions.
