The Catalytic Role of D-block Elements and Their Compounds for Improving Sorption Kinetics of Hydride Materials: A Review

The goal of finding efficient and safe hydrogen storage material motivated researchers to develop several materials fulfil the demand U.S. Department Energy (DOE). In past few years, metal hydrides, complex hydrides such as borohydrides alanates, have been researched found due their high gravimetric volumetric density. However, development these is still limited by thermodynamic stability sluggish kinetics. One methods improve kinetics use catalysts. Among known catalysts for this purpose, transition metals compounds are leading contender. present article reviews d-block including Ni, Co, V, Ti, Fe Nb boost up hydride systems. Various binary ternary oxides, halides combinations, porous structured hybrid designs metal-based Mxenes discussed enhance de/rehydrogenation cycling performance
