摘要：Although great progress has been made with respect to electron bridges, the electron mobility of the state-of-the-art electron bridges is far from satisfactory because of weak electrical conductivity. To overcome the above issue,cobalt phosphide(CoP), as a model electron bridge, was modified with superficial oxygen vacancies (OVs) and embedded into adefective bismuth oxychloride/carbon nitride (BiO_1-xCl/g-C₃N₄)Z-scheme heterojunction to obtain atomic-level insights into the effect of surface OVs on CoP electron bridges.Compared toBiO_1-xCl/g-C₃N₄andbismuth oxychloride/cobalt phosphide/carbon nitride (BiOCl/CoP/g-C₃N₄)composites, thedefective bismuth oxychloride/cobalt phosphide/carbon nitride (BiO_1-xCl/CoP/g-C₃N₄)heterojunctionexhibited remarkable photocatalytic redox performance,indicating that the surface OVs-assistedCoP electron bridge effectively boosted electrical conductivity and yielded ultrafast electron transfer rates. The theoretical and experimental results demonstrate that the surface OVsplay a critical role in improving the electrical conductivity of the CoP electron bridge, thereby accelerating electron mobility.This research provides insights intointerfacialOVs-modifiedtransition metal phosphide (TMP)electron bridges and their potential application in heterojunctions for energy crisis mitigation and environmental remediation.
