Hydrogen production from ammonia borane hydrolysis catalyzed by non-noble metal-based materials: a review
As a promising chemical hydrogen storage material, ammonia borane (AB, NH3BH3) has been receiving significant attention for its hydrogen release property. Researches on the development of effective catalysts for AB hydrolysis under mild conditions have been of potential application interest. In the last few years, some non-noble metal-based materials have been developed for dehydrogenation of AB via hydrolysis, due to their low cost, high activity, and high durability. Therefore, the summary and analysis of the rapidly developing non-noble metal catalyst systems without noble metals can better grasp the current development status to guide subsequent design and research. In this review, the latest advances in non-noble metal-based catalysts are summarized, which can be divided into the following categories: pure metal-based materials, metal-based compounds (borides, phosphides, and oxides), and metal/metal compound heterogeneous structures. Investigations into the composition, structure, and activity enhancement of the catalyst are further highlighted. Besides, hydrolysis mechanisms, catalyst persistence, and AB regeneration are also discussed. [GRAPHICS] .
