Abstract
In this work, active and stable catalyst for the dehydrogenation reaction of dimethylamine borane (DMAB) in solvent-free medium at room temperature has been prepared. The method is based on preparing in-situ monodispersed gold nanoparticles (AuNPs) by reducing the one dimensional polymer of gold(I):6-thioguanosine hydrogel by DMAB; which acts as reducing and stabilizing agent. Monitoring time-dependent to build the surface plasmon resonance (SPR) band for the formed AuNPs was carried out by performing a kinetic study using UV–Vis spectroscopy. Transmission electron microscopy (TEM) and atomic force microscopy (AFM) techniques were used to investigate the morphology of the AuNPs that obtained after reducing the hydrogel.
