本研究采用简单的浸渍还原法，在N2气氛下高温焙烧三聚氰胺和稻壳来制备氮掺杂稻壳活性炭载体(N-RHC)，再采用RuCl3溶液通过浸渍法将活性组分Ru负载到N-RHC载体上，得到Ru/N-RHC催化剂，探究了其对氨硼烷制氢的催化性能。结果表明，Ru负载量为5%（质量分数）的Ru/N-RHC催化剂具有较好的氨硼烷制氢催化性能，反应转化频率（TOF）达83.71 min−1，在光的照射下，该催化剂上氨硼烷水解的活化能从88.9 kJ/mol降到64.9 kJ/mol，且制氢速率与氨硼烷浓度以及催化剂浓度呈现正相关。

An efficient dehydrogenation catalyst is crucial for the application of ammonia borane (NH3BH3, AB) as a solid chemical hydrogen storage material. In this work, a kind of nitrogen-doped rice husk activated carbon (N-RHC) was prepared by roasting melamine and rice husk at high temperature under nitrogen atmosphere. With N-RHC as the support, the rice husk-based carbon supported ruthenium catalyst (Ru/N-RHC) was prepared through impregnation with the RuCl3 solution and its catalytic performance in the hydrolysis of ammonia borane to produce hydrogen was investigated. The results indicate that the Ru/N-RHC catalyst with a Ru loading of 5% performs excellently in the hydrolysis of ammonia borane; the reaction turnover frequency (TOF) reaches 83.71 min−1 and the apparent activation energy decreases from 88.9 to 64.9 kJ/mol under light irradiation. In addition, the hydrogen production rate is positively correlated with the content of ammonia borane and catalyst.
