Chemical compounds known as borohydrides, which contain the BH4− anion, have attracted a lot of attention in a number of sectors because of their special qualities and possible uses. These substances present a viable option for catalysis, hydrogen storage, and as reducing agents in organic synthesis.Borohydrides are appealing possibilities for hydrogen storage materials because of their high hydrogen content per weight. For this reason, sodium borohydride (NaBH4), one of the most researched borohydrides, has been thoroughly examined. Under the right circumstances, it can emit hydrogen gas, which might be a source of renewable energy. To improve practicality, however, issues like slow kinetics and high operating temperatures must be resolved. As adaptable reducing agents, borohydrides are essential to catalysis. They are used in a variety of organic transformations, including as reductive amination reactions and the reduction of carbonyl compounds to alcohols. In the manufacture of fine chemicals and pharmaceuticals, these reactions are essential. Borhydrides are appealing substitutes for conventional reducing agents like lithium aluminum hydride (LiAlH4), which can be more reactive and difficult to work with due to their mild reaction conditions.The creation of new materials based on borohydrides has increased their usefulness in additional contexts. In terms of stability and ionic conductivity, metal borohydrides, for example, have been studied as solid electrolytes for lithium-ion batteries. The characteristics of these materials are being optimized through ongoing research to increase battery performance and safety. Furthermore, heterogeneous catalysis has demonstrated the potential of borohydrides, especially in hydrogenation processes. Under mild reaction conditions, supported borohydride catalysts have shown remarkable activity and selectivity in the selective hydrogenation of unsaturated molecules.Notwithstanding its potential, borohydride practical applications nevertheless face difficulties. To fully utilize them in energy storage and catalytic applications, problems including hydrogen desorption kinetics, thermodynamic stability, and material synthesis pathways must be resolved.To sum up, borohydrides are a class of substances that have a variety of uses in materials science, catalysis, and hydrogen storage. Ongoing investigations focused on By resolving their drawbacks and utilizing their special qualities, they may be able to help advance many different technological disciplines toward more effective and sustainable methods.
