The in-situ prepared Ru(0) nano particles had an average particle size of 1.023 & PLUSMN; 0.097 nm. The monodisperse Ru(0) nanoparticles prepared with a very practical, inexpensive and rapid method were used as a catalyst in hydrogen production by the hydrolysis reaction of ammonia borane (AB). The Na-Alg@Ru catalyst containing 3 mg Ru(0) metal catalyzed the hydrolysis of 50 mM AB with 100% yield, and the activation energy (Ea) of the reaction was estimated as 61.05 kJ mol-1. In addition, the Na-Alg@Ru nanoparticles were prepared with acrylamide as p(AAm)/NaAlg@Ru hydrogel films suitable for use in hydrogen production in fuel cells, which represents a battery-like environment, and used for hydrogen production from AB. Thus, it was shown that the catalysts prepared in a few nm size could easily be used in battery-like environments.& COPY; 2023 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
