Strong electronic interactions between hexagonal boron nitride (h-BN) and Cu₂O protect the Cu−O bonds against electron attack through the transfer of accumulated electrons from Cu₂O to h-BN. This effect stabilizes the active Cu⁺ species during CO₂ electroreduction.

通过强电子相互作用稳定 Cu+ 以实现选择性和稳定的 CO2 电还原

六方氮化硼 (h-BN) 和 Cu _{2 O 之间的强电子相互作用通过将累积的电子从 Cu 2} O 转移到 h-BN 来保护 Cu-O 键免受电子攻击。这种效应在CO ₂电还原过程中稳定了活性Cu ^+物质。
