Synthesis and characterization of poly (N-vinyl-2-pyrrolidone)-stabilized nickel-ruthenium nanoparticles and their use as catalyst in the hydrolysis of ammonia borane

In this thesis study, poly(N-vinyl-2-pyrrolidone)-stabilized nickelruthenium nanoparticles were synthesized and characterized to catalyze hydrogen generation from ammonia borane, one of the most important solid chemical hydrogen storage materials. First, nickel-ruthenium bimetallic nanoparticles were synthesized by stabilization of PVP in aqueous solution. Later, synthesized bimetallic nanoparticles were characterized by advanced analytical methods such as XRD, XPS, (HR)TEM, and UV-visible spectroscopy. Lastly, kinetic studies were carried out to liberate hydrogen from hydrolysis of ammonia borane by successfully synthesized and characterized bimetallic nickel-ruthenium catalys.
