Bai, Peng; Tong, Xinli; Wan, Jun; Gao, Yiqi; Xue, Song published the artcile< Flower-like Bi2O2CO3-mediated selective oxidative coupling processes of amines under visible light irradiation>, Recommanded Product: 4-Bromobenzylamine, the main research area is bismuth oxycarbonate amine oxidation photocatalyst.
The photocatalytic selective transformation of amines is a green and cost-effective technol. to obtain value-added products in chem. industry. In this work, a series of bismuth-based photocatalysts including Bi2MoO6, Bi2WO6, Bi5O7Cl, Bi5O7Br, Bi5O7I, BiPO4, BiVO4, Bi2O3 and various morphol. Bi2O2CO3 (flower-like, sponge-like, plate-like and spherical) were synthesized and employed in the aerobic oxidative coupling of benzylamine. It is found that flower-like Bi2O2CO3 exhibited the highest photocatalytic activity, in which a 100% conversion of benzylamine with 99.0% selectivity of N-benzylidenebenzylamine was obtained at room temperature Moreover, the photocatalytic oxidative coupling processes of various aromatic and aliphatic amines were further investigated, and excellent yields and selectivities of corresponding products are attained. Then, based on characterization results (XRD, SEM, BET and XPS, etc.) of catalyst, high photocatalytic activity of flower-like Bi2O2CO3 is attributed to thin nanopetals, low band gap, the morphol. and large sp. surface area. Finally, a possible reaction mechanism is proposed for the photocatalytic oxidative coupling of benzyl amine.
