Cobalt-based Nanocatalysts-Catalyzed Hydrogen Generation from Borohydride for Chemical Hydrogen Storage

Text：The development of new, efficient, and safe hydrogen storage materials and hydrogen production technology is the key to realize the large-scale applications of hydrogen energy. Borohydride hydrogen storage materials, such as sodium borohydride and ammonia borane, have received widespread concern owing to their high hydrogen storage density and convenient storage and transportation. Co-based nanocatalysts, as representatives of non-noble metals, have been thoroughly studied as economical and efficient catalysts for hydrogen evolution from borohydrides hydrogen storage materials. However, no special review has been published on Co-based catalysts for hydrogen production from borohydrides hydrogen storage materials. In this review, we summarize the history and advances of Co-based catalysts for hydrogen storage from borohydrides, including their synthetic routes, promising performances, as well as potential catalytic mechanisms. We hope to establish the reliable structure-property relationship, and provide guidance for the catalyst design of hydrogen generation form borohydrides hydrogen storage materials in the future.
