They have been prepared by co-reduction of two metal ions in ethanol/water mixture by an alcohol reduction method and characterized by UV-Vis spectroscopy, TEM-EDX analysis, and X-ray photoelectron spectroscopy. They are recyclable and highly efficient catalysts for hydrogen generation from the hydrolysis of sodium borohydride even at very low concentrations and temperature, providing record average turnover frequency (TOF) value (549 mol•H2/mol•cat•min−1) and maximum hydrogen generation rate (16126 L•H2•min−1 (mol•cat)−1). Poly(N-vinyl-2-pyrrolidone)-protected platinum-ruthenium nano-particles also provide activation energy of 63.2 ± 2 kJ•mol−1 for the hydrolysis of sodium borohydride. %U http://www.genchemistry.org/EN/10.21127/yaoyigc20200003
