Ruthenium nanoparticles supported in the network of HES-p(AMPS) IPN hydrogel as efficient catalyst for hydrogen production from the hydrolysis of ethylenediamine bisborane

摘要

In this study, Ru(0) nanoparticles supported in 2-hydroxyethyl starch-p-(2-Acrylamido-2-methyl-1-propanesulfonic acid) interpenetrating polymeric network (HES-p(AMPS) IPN) were synthesized as hydrogel networks containing hydroxyethyl starch, which is a natural polymer with oxygen donor atoms. The structure and morphology of the prepared HES-p(AMPS) IPN hydrogel and Ru@HES-p(AMPS) IPN catalyst were characterized using Fourier transform infrared spectroscopy (FT-IR), scanning electron microscope (SEM), X-ray diffraction (XRD), and transmission electron microscope (TEM). Ru@HES-p(AMPS) IPN was used as catalyst for hydrogen production from the hydrolysis of ethylenediamine bisborane (EDAB). The activation parameters for the hydrolysis reaction of EDAB catalyzed by Ru@HES-p(AMPS) IPN were calculated as E-a = 38.92 kJ mo1(-1) , Delta H-# = 36.28 kJ mol(-1) , and Delta S-# = -111.85 J mol(-1) K-1 , respectively. The TOF for the Ru@HES-p(AMPS) IPN catalyst was 2.253 mol H-2 (mol Ru(0) min)(-1 ). It was determined that Ru@HES-p(AMPS) IPN, a reusable Hydrolysis catalyst, still had 81.5% catalytic activity after the 5th use. (C) 2020 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
