“…However, some researchers have recounted that it is caused by the existence of a stable formate group/intermediate which results from the adsorption of H 2 on the surface of Cu [62]. Iglesia and Boudart [58] based their investigation on the formate reaction-pathway, where they obtained an activation energy of 94.5-100 kJ/mol for FA-decomposition using Cu catalysts on different supports; same results were obtained for preferentially oriented (PO)-and polycrystalline (PC)-Cu catalysts [63][64][65]. Their investigation led to the conclusion that there was no direct correlation between the observed turnover rates (TORs)/Turn over Frequencies (TOFs) of hydrogen and the particle-size of copper as well as the catalyst support.…”

Practically, an ideal catalyst for Formic acid-decomposition is one that best suits the reaction and significantly lowers its activation energy and improves the reaction rate under favourable conditions. Several catalysts for Formic Acid (FA)-decomposition reactions were examined. Based on the volcano curve and the potential of copper to give high hydrogen yields, emphasis was placed on a Cu-catalysed reaction as potential system for sustainable hydrogen production. Some recent advances in hydrogen production from formic acid were discussed and an effective system for FA-decomposition for hydrogen production was proposed. Since helium can be stored in weather balloons and weighs almost the same as hydrogen, a hydrogen buffer made from polyester fabric and coated with polyurethane or a hydrogen cylinder/tube was proposed for storing hydrogen for use as transportfuel. Also, due to the nature of the mechanisms/pathways describing FA-conversion reactions at the sites or surfaces of the copper-nanocatalysts, it is evident that the Cu(2 1 1) coordination site possesses the highest activation energy relative to those of Cu(1 0 0) and Cu(1 1 1), hence, the reason for the noticeable high or low hydrogen yields. Thus, the potential of Cu giving high hydrogen yields from FA spans from the reactions of FA at the Cu(1 1 1) and Cu(1 0 0) sites.
