Herein, a facile strategy has been demonstrated for developing noble-metal-free bifunctional electrocatalysts by successfully preparing a polyoxovanadoborate framework compound, i.e., [Na10(H2O)18][(VO)12(?3-OH)6(B3O7)6]�5H2O, i.e., NVBO-I. Anionic vanadoborate clusters are interconnected through a cationic sodium aquated chain to form a three-dimensional framework structure. The compound exhibits remarkable bifunctional activity for oxygen and hydrogen evolution reactions over many well-engineered and state-of-art electrocatalysts under a similar catalytic environment. � 2022 American Chemical Society.en-USElectrocatalystsElectrolysisHydrogenOxygenBifunctional activityBifunctional electrocatalystsCatalytic environmentCationicsFramework structuresHydrogen evolution reactionsInorganicsMetal freeThree-dimensional frameworksPrecious metalsArticlehttps://pubs.acs.org/doi/10.1021/acs.cgd.2c00258
