Insights into the catalytic activity of Ru/NaY catalysts for efficient H2 production through aqueous phase reforming

Abstract

Ruthenium nanoparticles supported on NaY zeolite catalysts synthesized by simple ion exchange method. The structural and morphological features of catalysts systematically investigated by numerous techniques such as N2-sorption, XRD, CO2-TPD, H2-TPR, TEM, SEM, ICP-OES, TGA, CHN analysis, XPS, In-situ CO-FTIR, and NMR spectroscopy. These novel Ru-NaY catalysts were highly active and selective for H2 production through aqueous phase reforming (APR) of glycerol and ethylene glycol. Among various catalysts evaluated for H2 production, 3wt%Ru-NaY catalyst demonstrated highest catalytic performance with excellent H2 selectivity, and this catalyst exhibit better activity as compared to many states of the art catalysts reported so far. The superior activity of 3wt%Ru-NaY was attributed to the appropriate Ru metal loading, good metal dispersion, small size of Ru nanoparticles, better metal-support interaction,and higher availability of active catalytic site (Ru °) and facilitated water gas shift reaction (WGS). This catalytic result clearly shows that NaY zeolite supported Ru nanoparticles catalysts have excellent potential for H2 production from biomass-derived compounds.
