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 ... -
