N2 - Benzylamine coupling is a very important reaction for the synthesis of imine but still faces many challenges.Herein, we present a highly effective strategy towards the coupling reaction by using environmentallyfriendly catalysts. These catalysts are composed of Cu/Cu2O/Cu3N heterostructures supported by C3N4tubes and the composites were synthesized by one-step hydrothermal treatment followed bycalcination. Cu2O, Cu3N, and C3N4 all are responsive to visible light and the heterojunction formed cangreatly enhance the charge separation. When used as photocatalysts for oxidative self-coupling ofbenzylamine at a low temperature of 323 K in air, Cu/Cu2O/Cu3N/C3N4 was able to give conversion andselectivity values of up to 99% and 98%, respectively. The high efficiency of the catalysts is attributable totheir ability to generate large quantities of free radicals (such as $OH and $O2) under visible-light irradiation
