    Vanadate Encapsulated Polyoxoborate Framework with [V12B18] Clusters: An Efficient Bifunctional Electrocatalyst for Oxygen and Hydrogen Evolution Reactions
    (American Chemical Society, 2022-07-11T00:00:00) Rom, Tanmay; Biswas, Rathindranath; Haldar, Krishna Kanta; Saha, Uttam; Rayaprol, Sudhindra; Paul, Avijit Kumar
    Widespread contemporary attention has grown over the years in the search for a new functional and robust inorganic framework system with the advent of exciting applications. 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.

    Charge Separated One-Dimensional Hybrid Cobalt/Nickel Phosphonate Frameworks: A Facile Approach to Design Bifunctional Electrocatalyst for Oxygen Evolution and Hydrogen Evolution Reactions
    (American Chemical Society, 2021-09-30T00:00:00) Rom, Tanmay; Biswas, Rathindranath; Haldar, Krishna Kanta; Sarkar, Sourav; Saha, Uttam; Paul, Avijit Kumar
    Two new organoamine templated one-dimensional transition metal phosphonate compounds are synthesized, and their bifunctional electrocatalytic activities are examined in highly alkaline and acidic media. Compared with state-of-the-art materials, the cobalt phosphonate system is a new fabrication of sustainable and highly efficient catalysts toward electrochemical water splitting systems. � 2021 American Chemical Society.
