Abstract
The employment of poly(N-vinyl-2-pyrrolidone)-protected rhodium nanoparticles (3.8 ± 1.2 nm) as highly efficient catalysts in the hydrolysis of hydrazine borane for hydrogen generation is reported. The catalyst is prepared by reduction of rhodium metal ion in ethanol/water mixture by an alcohol reduction method and characterized by TEM analysis, UV-Vis spectroscopy, and X-ray photoelectron spectroscopy. It is durable and highly efficient catalysts for hydrogen generation from the hydrolysis of hydrazine borane even at very low concentrations and temperature, providing an average turnover frequency of 75 min-1. Poly(N-vinyl-2-pyrrolidone)-protected rhodium nanoparticles also provide activation energy of 58.6 ± 2 kJ/mol for the hydrolysis of hydrazine borane.
