Hydrogen production from chemical hydrogen storage materials over copper‐based catalysts

Abstract Hydrogen, as a clean and efficient energy source, is one of the important energy carriers in the future. However, the safe storage and delivery of hydrogen is still a bottleneck in its practical applications. Chemical hydrides (such as NaBH 4 , NH 3 BH 3 , N 2 H 4 ·H 2 O, N 2 H 4 BH 3 , and HCOOH) are considered as potential chemical hydrogen storage materials that can achieve rapid on‐site hydrogen production. At present, the most critical issue for them is to develop economic catalysts to achieve efficient hydrogen production from chemical hydrides. Copper (Cu) is considered as a promising catalyst that is one of the most reactive metals among the first‐row transition metals and economically cheap. In this review, we outline the recent advancements of Cu‐based catalysts in catalyzing hydrogen production from chemical hydrides. Moreover, the synthesis methods, characterization techniques, and hydrogen production catalytic activity of Cu‐based catalysts were also introduced. Finally, a brief conclusion and outlook are given for the application of Cu‐based catalysts in the dehydrogenation of chemical hydrides. We hope that this review will stimulate interest in the promising research area of Cu‐based catalysts for the dehydrogenation of chemical hydrides.
