Abstract: As a kind of clean energy to promote global energy transition，hydrogen energy has gradually become a research hotspot in the world′s energy field.It is found that hydrogen has great significance in agricultural energy application and plant signal sensing.A high efficiency catalyst（Ag/Co-B/CTAB）was prepared to catalyze hydrolysis of ammonia-borane（AB）for hydrogen production.The physical and chemical properties of Ag/Co-B/CTAB catalyst were characterized by FTIR，XRD，XPS and other technologies，and effects of different temperature，catalyst content and AB concentration on the hydrolysis of AB for hydrogen production were analyzed.Results showed that hydrogen production rate of Ag/Co-B/CTAB catalyst was 16.185 L/（min·g catalyst）at 30 ℃，while hydrogen production rate of Co-B/CTAB catalyst was 10.76 L/（min·g catalyst），which greatly increased hydrogen production rate of AB hydrolysis reaction.In addition，activation energy for hydrolysis of AB catalyzed by Ag/Co-B/CTAB was also low（12.581 kJ/mol）.This research is of great significance for subsequent development of large-scale and effective applications of hydrogen in agriculture.
