This review focuses on the advancements in Cu-based catalysts for hydrogen production from chemical hydrides, including sodium borohydride (SB), ammonia borane (AB), and hydrazine (HH). The synthesis methods, characterization techniques, and catalytic activities of these catalysts are discussed. Cu-based catalysts have shown promising performance in hydrogen production due to their low cost and high reactivity. However, challenges such as catalyst stability and regeneration of byproducts remain. The review highlights the potential of Cu-based catalysts in overcoming these limitations and their application in the dehydrogenation of chemical hydrides.This review focuses on the advancements in Cu-based catalysts for hydrogen production from chemical hydrides, including sodium borohydride (SB), ammonia borane (AB), and hydrazine (HH).
