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-CO₂ battery. The existence of BN-GN vdWsH can reduce the overpotential more than 700 mV compared with reduced graphene oxide during the CO₂ reduction reaction (CO₂RR) and CO₂ evolution reaction (CO₂ER), and it extended cyclic stability more than three times, which was one of the most outstanding non-metallic catalysts. The reasonable structure design made it work as a high efficient electrocatalyst, which shed light on the development for functional treatment of catalytic materials.

合理调节电子耦合以促进电荷转移和激子分离被认为是一种很有前途的催化方法。基于二维 (2D) 材料的范德华异质结 (vdWsH) 材料工程将是优化所制备的外在物理化学特性的潜在途径。然而，它仍然是一块几乎未开垦的土地，等待催化探索。在此，我们在非金属还原氧化石墨烯 (GN) 催化剂中引入了惰性h -氮化硼 ( h -BN) 并构建了 BN-GN vdWsH。理论计算表明h- BN可以有效地改变石墨烯的电子性质。随着h-BN，BN-GN vdWsH可以明显提高Li-CO ₂电池的催化活性。在CO ₂还原反应(CO ₂ RR) 和CO ₂析出反应(CO ₂ ER)过程中，BN-GN vdWsH 的存在与还原氧化石墨烯相比可降低700 mV 以上的过电位，并将循环稳定性延长3 倍以上。时代，这是最杰出的非金属催化剂之一。合理的结构设计使其成为一种高效的电催化剂，为催化材料功能处理的发展提供了启示。
