A new highly active polymer supported ruthenium nanocatalyst for the hydrolytic dehydrogenation of dimethylamine-borane
Abstract
Abstract Herein, we report a highly active Ru@PVP nanocatalyst for the hydrolytic dehydrogenation of dimethylamine-borane under room conditions. The Ru@PVP nanocatalyst was readily prepared, stabilized and used effectively in the catalytic dehydrogenation reaction of dimethylamine-borane in water at room conditions. The prepared Ru@PVP nanocatalyst was characterized using advanced analytical methods such as XPS, XRD, HR-TEM, etc. The characterization analyzes shown that Ru metals are uniformly distributed on the PVP support surface; the mean particle of catalyst size was found to be 2.78 ± 0.16\u202fnm. The catalytic test showed that DMAB had a high catalytic activity with Ru@PVP in aqueous solutions, and TOF value was found to be 2500.52 h−1 for hydrolytic dehydrogenation of DMAB at room conditions. The study also included kinetic data such as activation parameters for different temperatures, catalyst concentration, and substrate concentration experiments.
