Abstract: Hydrogen (H2), as a renewable, zero-carbon emission and earth-abundant energy carrier, is considered to be one of the effective solutions to the energy crisis and environmental problems. Since H2 is highly flammable and explosive, it is hard for storage and transportation and its application is severely restricted. Therefore, the safe and efficient storage and controllable release of hydrogen is urgently crucial. It is well-known that ammonia borane (NH3BH3, AB for short) has a high hydrogen content, and is stable at room temperature, non-pollutant, non-toxic and soluble in water, and it can not react with water at room temperature. In presence of a suitable catalyst, AB can easily hydrolyze in aqueous media to liberate H2, so that AB is recognized to be an ideal candidate of hydrogen energy materials. However, the lack of low-cost, stable, environmentally friendly, easily separable and recyclable high-performance catalysts seriously hinders the development and applications of AB-based hydrolytic hydrogenation technology. Therefore, rational design and controllable construction of low-cost and high-performance catalysts for AB hydrolytic hydrogenation is greatly challenging for applications of AB-based hydrogen energy. At present, investigation on high performance catalysts for hydrolytic hydrogenation of ammonia borane is very active, and has become one of the hot topics in the field of hydrogen energy research. Hitherto now, the heterogeneous catalysts used in the hydrolytic hydrogenation of ammonia borane can be classified into two categories: non-supported and supported. In particular, the supported ultrafine nanocatalysts have attracted wide attention and extensive interests, and their research shows a rapid development trend. In this contribution, preparations of the ultrafine nanocatalysts supported on carbon based materials, layered double hydroxides (LDHs), oxides, metal-organic frameworks (MOFs), organic polymer materials, as well as the catalytic performances and mechanisms in hydrolytic hydrogenation of ammonia borane are reviewed, and then, the problems to be solved in this research are summarized, and prospects about further researches are presented.
