Gao, Xiaoqing; Zhu, Shanhui; Dong, Mei; Wang, Jianguo; Fan, Weibin published the artcile< Ru/CeO2 catalyst with optimized CeO2 morphology and surface facet for efficient hydrogenation of ethyl levulinate to γ-valerolactone>, Computed Properties of 112-63-0, the main research area is ruthenium ceria catalyst surface facet ethyl levulinate hydrogenation valerolactone.
Three Ru/CeO2 catalysts with different CeO2 morphol. (nanorod, nanocube and nano-octahedra) mainly exposed (1 1 0) + (1 0 0), (1 0 0) and (1 1 1) facets for hydrogenation of biomass-derived Et levulinate (EL) to valuable γ-valerolactone (GVL). Ru/CeO2-rod with exposed (1 1 0) crystal plane obtained the highest GVL yield (99.4%) and best productivity (13140 h-1). The surface facets of CeO2 supports not only affect the chem. states of Ru species but also tune the concentration of oxygen vacancy in Ru-CeO2 interface. The concentration of oxygen vacancy shows a linear relationship with GVL production rate. DFT calculations indicate that the lactonization of CH3CHOCH2CH2CO* to produce GVL is the rate-determining step in EL hydrogenation, and Ru10/CeO2 (1 1 0) with more oxygen vacancy has low activation energy barrier, compared to Ru10/CeO2 (1 0 0) and Ru10/CeO2 (1 1 1).
Journal of Catalysis published new progress about Adsorption. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Computed Properties of 112-63-0.
