Abstract
The green and clean hydrogen energy carrier can be produced rapidly through ammonia borane hydrolysis under mild conditions. Essential to such rapid production is the development of efficient nanocatalysts. Herein, Pt and Cu were dispersed on the Co3O4 support by the impregnation method to prepare the PtCu/Co3O4 nanocatalyst for ammonia borane hydrolysis. The introduction of Cu effectively promoted the reduction of Pt species to metallic Pt0, enhancing the hydrogen generation rate remarkably. The synergistic effect between Pt and Cu further boosted the hydrogen generation rate, endowing the catalyst with outstanding catalytic activity. The optimized PtCu(0.5)/Co3O4 catalyst presented superior catalytic performance, and the TOF value achieved 6310 min1 at 298 K. The catalyst retained high catalytic activity after 5 cycles of reuse. This work provides referable ideas for nanocatalyst design, preparation, and the study of structure−activity relationships.
Hydrogen production via catalytic steam reforming of high-carbon hydrocarbons, with low cost, strong adaptability, and easy industrialization, is one of the core technologies for addressing the hydrogen supply bottleneck of fuel cells. However, traditional synthesis methods usually lead to an uncontrollable chemical...

The electrocatalytic co-reduction of CO2 and nitrate to urea offers a sustainable route for carbon fixation, nitrogen waste recycling, and high-value chemical production. However, the rational design of efficient electrocatalysts with synergistic activation capability toward both reactants and the ability to suppress s...
Ammonia borane (AB) is an ideal chemical hydrogen storage material owing to its high gravimetric and volumetric hydrogen capacities. However, the practical application through hydrolysis calls for catalysts that are efficient, stable, and low-cost. In this work, a CoxC/TiO2 catalyst was synthesized by pyrolyzing a Co-M...
Enhancing the highly selective photocatalytic generation of hydroxyl radical for water purification is extremely desirable but remains challenging since it normally requires a series of reactions associated with different catalysts. Here we report a synergistic catalyst (PdSAs+NPs/Vvac-BiVO4) with dual-functional activ...
Hydrolysis of ammonia borane (AB) for hydrogen production is an efficient and sustainable method for hydrogen energy conversion and transportation.
