Kumaravel, Sakthivel published the artcileRu/TiO2 nanostructured catalysts: synthesis, characterization and catalytic activity towards hydrogenation of ethyl levulinate, Product Details of C7H12O3, the main research area is ruthenium titania ethyl levulinate catalyst hydrogenation nanostructure.
Pristine TiO2 and x% Ru/TiO2 catalysts with different weight% of Ru (x%= 1.5%, 2%, 2.5% and 3%) were synthesized using sol-gel and simple impregnation methods. Different characterization techniques such as X-ray diffraction (XRD), Fourier transform IR spectroscopy (FT-IR), SEM (SEM), High-resolution transmission electron microscope (HR-TEM), Inductively coupled plasma-optical emission spectrometry (ICP-OES) and Thermogravimetry/DTA (TG/DTA) were used to study the physicochem. and morphol. properties. The XRD patterns of the as-prepared pristine TiO2 catalyst showed high crystalline nature. The HR-TEM images revealed that the Ru nanoparticles (NPs) were evenly dispersed on the TiO2 surface. The prepared catalysts were evaluated for their catalytic activity towards the liquid phase hydrogenation of Et levulinate under mild reaction conditions (ambient H2 pressure). Among the various catalysts, 2.5% Ru/TiO2 catalyst showed the maximum catalytic activity of 79% Et levulinate (EL) conversion with 82% selectivity of γ-valerolactone (GVL). The recyclability test revealed that the most active 2.5% Ru/TiO2 also showed the highest stability of the catalyst under optimized exptl. conditions.
