Bifunctional catalysts with improved hydrothermal stability for the hydrolytic hydrogenation of cellulose into polyols
The increase in the world’s energy needs has caused a renewed interest in finding green ways to produce fuels. In this work, we present a study of the hydrolytic hydrogenation of cellulose on bifunctional catalysts for the ...
Catalytic conversion of CO2 to hydrocarbons
The production of methanol and dimethyl ether via CO2 hydrogenation was studied using Pd catalysts supported on α-Ga2O3, α-β-Ga2O3 and β-Ga2O3 polymorphs. The catalytic activity improves with the increase in the content ...
Effect of protic and aprotic polar solvents on the heterogeneous catalytic conversion of hexoses
We studied the synthesis, the characterization and the solvent effect on the catalytic performance of materials with Brønsted or Lewis acidity on the hexose conversion towards value-added molecules such as 5-(hydroxymeth ...
Conversion of carbohydrates to alpha-hydroxy-acids over Lewis acidic HF-, SN- and ZR- beta zeolite catalysts using gamma-valerolactone and water as solvent
The incorporation of Sn, Hf and Zr in the structure of Beta zeolite using a post-synthetic method gives catalysts with Lewis acidity that are effective for the conversion of C6 sugars to alpha-hydroxy acids (AHAs), such ...
Catalytic conversion of biomass renewable feedstocks to platform molecules using Brønsted acid catalysts
The fractionation of sugarcane bagasse, plantain peel and brewer’s spent grains to glucose, xylose and lignin was studied using 0.50 and 0.05 wt% H2SO4 as catalyst in a mixture of 80:20 wt% γ-valerolactone:water. We ...
Conversion of biomass derived feedstocks to platform molecules using bifunctional mesostructured silica based catalysts
The combination of Brønsted acidity with metallic functionality in a mesoporous catalyst offers a potential pathway for the conversion of cellulose into sugar alcohols that may be used as a sustainable source of renewable ...
