Reasonably regulating electronic coupling to promote charge transfer and exciton separation has been regarded a promising approach in catalysis.The material engineering of van der Waals heterojunction(vdWsH)based on two-dimensional(2D)materials would be a potential way to optimize the as-prepared extrinsic physicochemical characteristics.However,it was still an almost uncultivated land waiting for exploration in catalysis.Herein,we introduced the inert h-boron nitride(h-BN)in non-metal reduced graphene oxide(GN)catalysts and constructed BN-GN vdWsH.The theoretical calculation demonstrated that the h-BN can effectively modify the electronic properties of graphene.With the introduction of h-BN,the BN-GN vdWsH can obviously enhance the catalytic activity of Li-CO_(2) battery.The existence of BN-GN vdWsH can reduce the overpotential more than 700 mV compared with reduced graphene oxide during the CO_(2) reduction reaction(CO_(2)RR)and CO_(2) evolution reaction(CO_(2)ER),and it extended cyclic stability more than three times,which was one structure design made it work as a high efficient electrocatalyst,catalytic materials. 展开更多
