Exploring the "on–off" control of hydrogen release remains a critical issue for efficiently on-demand utilization energy. In this work, new storage strategy loading ammonia borane (AB) solid and metal catalyst Co in halloysite nanotube aerogel (AB@Co/HNTA) is proposed controlled from AB hydrolysis by controlling added water. The results show that nanoparticles with size 3.07 nm are uniformly distributed on HNTA surface, can be packaged into to form bulk composite. Controlled generation achieved AB@Co/HNTA system, which turned off amount water aerogel. Further, decorated (Co/HNTA) reused encapsulate next run after complete hydrolysis. This work provides approach application field "on-board" device, solid-system hydrolytic extended any other porous material loaded catalysts.
