An alternative cobalt oxide-supported platinum catalyst for efficient hydrolysis of sodium borohydride

Synergistic catalysis of Au-Co@SiO2 nanospheres in hydrolytic dehydrogenation of ammonia borane for chemical hydrogen storage

“…5 and Table S1 †), the evolution of 7, 65, and 65 mL of hydrogen was finished in 20.0, 81.0, and 34.5 min, respectively. In the present reaction system, hydrogen is generated via the following two reactions: NaBH 4 + 2H 2 O / Na + + BO 2 À + 4H 2 (1) and (2). According to the theoretical calculations, the total yield of hydrogen via reaction 1 and reaction 2 is about 65 mL.…”

“…There have been a large number of reports on hydrogen storage materials. [1][2][3][4][5][6][7][8][9] However, big challenges still remain. Ammonia borane (NH 3 BH 3 , AB) has a hydrogen capacity as high as 19.6 wt%, exceeding that of gasoline and making it an attractive candidate for chemical hydrogen storage applications.…”

Liquid-phase chemical hydrogen storage materials

“…46 A number of heterogeneous catalysts based on metals or metal compounds or metal alloys have been reported to be active for catalytic hydrolysis of sodium borohydride in alkaline solutions under ambient conditions, including Co, Ni, Fe, Ru, Pt, Pd, Ru-Cu, Ru-Pd, Ru-Ag, Ru-Pt, Pt-Ag etc. 33,[47][48][49][50][51][52][53][54][55][56][57][58][59][60][61][62] The efficiency of the catalyst has been investigated in terms of the type and form of the catalyst. 54,55 Initially, noble metal catalyzed hydrolysis of NaBH 4 was investigated by using metal salts e.g.…”

Reaction of Co3O4 Nanocrystals on Graphene Sheets to Fabricate Excellent Catalysts for Hydrogen Generation

“…Due to the high hydrogen content up to 10.8 wt %, NaBH 4 is recognized as an ideal hydrogen-storage material. From NaBH 4 , highly pure hydrogen without CO, which is notoriously toxic for the catalysts of fuel cells, will be obtained readily. − Therefore, various catalysts have been explored to catalyze NaBH 4 hydrolysis for facile hydrogen production. , Because of the awkwardness of its high cost and limited noble metal resources, the development of non-noble metal catalysts, such as Co-based catalysts, is of special significance and is expected to replace the noble metal counterparts (Pt, Ru) in future practical applications. , The interfaces and Mott–Schottky junctions between two nanostructures will generally show superior catalytic performances because of the unique electronic and geometric interaction.…”
