Boron compounds have recently attracted attention in hydrogen production since they contain many hydrogen atoms. Among these compounds, ammonia borane, which has high hydrogen density (in weight basis), can be used to produce hydrogen through a hydrolysis reaction. However, since the ammonia borane solution is highly resistant to hydrolysis under ambient conditions, there is a need for active and stable catalysts to accelerate the reaction. In this review paper, unsupported and carbon-based supported metal catalysts used for hydrogen production through the hydrolysis of ammonia borane are presented. Noble metal catalysts (Ru, Rh, Pd, Pt and their binary and ternary alloys) and non-noble metal catalysts (Co, Ni, Fe, Cu and their binary and ternary alloys) were examined. The activation energy of reaction and turnover frequency (TOF) values were compared for these catalysts. Among the unsupported catalysts, it was concluded that the multi-metal catalyst systems (binary, ternary and quaternary) have higher catalytic activity than a single use of the same metals. In addition, the comparison showed that the supported catalysts are more resistant to catalytic cycles and suitable for long-term use. It was observed that CNT supported Rh (TOF = 706 mol H₂ mol cat⁻¹ min⁻¹) and graphene supported Ru (TOF = 600 mol H₂ mol cat⁻¹ min⁻¹) catalysts are the most active catalysts for the hydrogen generation from the ammonia borane at room temperature.

硼化合物由于包含许多氢原子，最近在氢生产中引起了人们的注意。在这些化合物中，具有高氢密度（以重量计）的氨硼烷可用于通过水解反应产生氢。但是，由于氨硼烷溶液在环境条件下高度抗水解，因此需要活性和稳定的催化剂来加速反应。在这篇综述文章中，提出了用于通过氨硼烷的水解生产氢气的无载体和碳基载体金属催化剂。检查了贵金属催化剂（Ru，Rh，Pd，Pt及其二元和三元合金）和非贵金属催化剂（Co，Ni，Fe，Cu及其二元和三元合金）。比较了这些催化剂的反应活化能和周转频率（TOF）值。在无载体催化剂中，得出的结论是，多金属催化剂体系（二元，三元和四元）比单次使用相同的金属具有更高的催化活性。此外，比较表明，负载型催化剂对催化循环的耐受性更高，适合长期使用。观察到CNT负载Rh（TOF = 706 mol H₂ mol cat ^-1 min ^-1）和石墨烯负载的Ru（TOF = 600 mol H ₂ mol cat ^-1 min ^-1）催化剂是室温下由氨硼烷生成氢的最活泼的催化剂。
