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 ...
Facile mechanochemical modification of g-C3N4 for selective photo-oxidation of benzyl alcohol
(2019)
Graphitic carbon nitride enriched with ZnO or Fe2O3 were synthesized using a simple one-pot mechanochemical method. By using this method, composite samples were synthetized without the production of any potentially hazardous ...
Highly active catalytic Ru/TiO2 nanomaterials for continuous production of γ-valerolactone
(2019)
Green energy production from renewable sources is an attractive but challenging topic to face the likely energy crisis scenario in the future. In the current work, a series of versatile Ru/TiO2 catalysts were simply ...
Towards industrial furfural conversion: selectivity and stability of palladium and platinum catalysts under continuous flow regime
(2019)
Furfural is an important biorefinery platform chemical, derived from hemicelluloses which represent an import fraction of lignocellulosic biomass feedstocks and waste streams originating from them. Recently, promising ...
A Sustainable Approach for the Synthesis of Catalytically Active Peroxidase-Mimic ZnS Catalysts
(ACS Publications, 2019)
Zinc sulfides are emerging as promising catalysts in different fields such as photochemistry or organic synthesis. Nevertheless, the synthesis of ZnS compounds normally requires the utilization of toxic sulfur precursors, ...
Sustainable protocol for the reduction of nitroarenes by heterogeneous Au@SBA‐15 using NaBH4 under flow conditions
(Wiley, 2019)
Gold‐incorporated SBA‐15 catalyst was prepared by a solvent‐free ball milling approach. The catalyst showed high reactivity and selectivity in the reduction of a variety of nitroarenes to anilines operating in absolute ...
Heterogeneously Catalyzed Synthesis of Imidazolones via Cycloisomerizations of Propargylic Ureas Using Ag and Au/Al SBA-15 Systems
(ACS, 2019)
The synthesis of imidazolones through the cycloisomerization of ureas, specifically propargylureas, has gained attention due to the large availability of starting materials. However, this type of synthesis normally requires ...
Efficient Ru-based scrap waste automotive converter catalysts for the continuous-flow selective hydrogenation of cinnamaldehyde
(Royal Society of Chemistry, 2019)
The selective, efficient and sustainable continuous flow hydrogenation of a α,β-unsaturated aldehyde, i.e. cinnamaldehyde, to the corresponding unsaturated alcohol, i.e. cinnamyl alcohol, using a novel catalyst based on ...
The dark side of biomass valorization: A laboratory experiment to understand humins formation, catalysis and green chemistry
(ACS Publications, 2019)
This laboratory experiment introduces students to an important reaction in biomass valorization and allows them to gain a practical understanding of green chemistry. Acid-catalyzed dehydration reactions of fructose to ...
Reconstruction of humins formation mechanism from decomposition products: A GC-MS study based on catalytic continuous flow depolymerizations
(Elsevier, 2019)
Humins, a by-product of biomass chemical conversion technologies, still present controversies in their structural and mechanistic identification. Traditional studies of the structure and mechanism have focused so far on ...
