Electron delocalization of robust high-nuclear bismuth-oxo clusters for promoted CO₂ electroreduction.

ABSTRACT: The integration of high activity, selectivity and stability in one electrocatalyst is highly desirable for electrochemical CO₂ reduction (ECR), yet it is still a knotty issue. The unique electronic properties of high-nuclear clusters may bring about extraordinary catalytic performance; however, construction of a high-nuclear structure for ECR remains a challenging task. In this work, a family of calix[8]arene-protected bismuth-oxo clusters (BiOCs), including Bi₄ (BiOC-1/2), Bi₈Al (BiOC-3), Bi₂₀ (BiOC-4), Bi₂₄ (BiOC-5) and Bi₄₀Mo₂ (BiOC-6), were prepared and used as robust and efficient ECR catalysts. The Bi₄₀Mo₂ cluster in BiOC-6 is the largest metal-oxo cluster encapsulated by calix[8]arenes
