Catalytic insights into the production of biomass-derived side products methyl levulinate, furfural and humins
(Elsevier, 2017)Biomass conversion into useful chemicals, materials and fuels emerged as a promising alternative toward replacing the current production of most of these commodities and specialty products from petroleum feedstocks. ... -
Chemoselective hydrogenation of furfural to furfuryl alcohol on ZrO2 systems synthesized through the microemulsion method
(Elsevier, 2018)Different solids consisting in hydrous zirconia were synthesized by the water in oil microemulsion technique (ME series). For comparative purposes, diverse solids were also obtained by the conventional sol-gel method ... -

Citrate-Stabilized Gold Nanoparticles as High-Performance Electrocatalysts: The Role of Size in the Electroreduction of Oxygen
(ACS, 2019)Fuel cells stand out as among the most promising alternatives for non-sustainable fossil fuel based economy. Efficient electrocatalysts for the oxygen reduction reaction (ORR) are required for the mass application of fuel ... -
CO2 Separation and Capture Properties of Porous Carbonaceous Materials from Leather Residues
(MDPI, 2013)Carbonaceous porous materials derived from leather skin residues have been found to have excellent CO2 adsorption properties, with interestingly high gas selectivities for CO2 (α > 200 at a gas composition of 15% CO2/85% ... -
Cobaloxime tethered pyridine-functionalized ethylene-bridged periodic mesoporous organosilica as efficient HER catalyst
(Royal Society of Chemistry, 2022)An efficient cobaloxime hydrogen production catalyst has been synthesized through coordination of a cobalt complex (Co(dmgH2)(dmgH)Cl2) on an ethylene-bridged periodic mesoporous organosilica (PMO) containing pyridine ... -

Continuous flow alcoholysis of furfuryl alcohol to alkyl levulinates and angelica lactones using zeolites
(2019)The present work explores the catalytic activity of various zeolites for the production of methyl levulinates from hemicellulose derived furfuryl alcohol and explores the performance of H-ZSM-5-50 in continuous flow ... -
Continuous flow conversion of biomass-derived methyl levulinate into gamma valerolactone using functional metal organic frameworks
(2019)Zirconium based metal organic framework, UiO-66 (Zr), was successfully synthesized via solvothermal method, followed by various characterization including XRD, thermal analysis, N2 physisorption and TEM. As-synthesized ... -
Continuous flow synthesis of menthol via tandem cyclisation–hydrogenation of citronellal catalysed by scrap catalytic converters
(Royal Society of Chemistry, 2019)A continuous flow synthesis of menthol starting from citronellal catalysed by scrap catalytic converters is reported. The reaction was conducted in a tandem system connecting in series two catalytic systems, with the first ... -
Continuous-Flow Hydrogenation of Methyl Levulinate Promoted by Zr-Based Mesoporous Materials
(MDPI, 2019)Several Zr-based materials, including ZrO2 and Zr-SBA-15, with different silicon/zirconium molar ratios, and ZrO2/Si-SBA-15 (where SBA-15 stands for Santa Barbara Amorphous material no. 15), have been prepared as hydrogenation ... -
Continuous-Flow Processes in Heterogeneously Catalyzed Transformations of Biomass Derivatives into Fuels and Chemicals
(MDPI, 2012)Continuous flow chemical processes offer several advantages as compared to batch chemistries. These are particularly relevant in the case of heterogeneously catalyzed transformations of biomass-derived platform molecules ... -
Controlled photodeposition of Pt onto TiO2-g-C3N4 systems for photocatalytic hydrogen production
(Elsevier, 2022)Platinum (0.5 wt. %) was photodeposited on g-C3N4-TiO2 systems using UV or Vis light. Different absorption by semiconductors seemed to somehow influence resulting platinum particle size and distribution. Thus, lower platinum ... -
