Valorisation of humins-extracted 5-Methoxymethylfurfural: towards high added value furanics via continuous flow catatalytic hydrogenation
(ACS Publications, 2019)
The formation of humins is one drawback of biomass valorization (e.g. hemicellulosic fraction) towards platform chemicals and fuels. Furanic compounds including 5-hydroxymethylfurfural and 5-methoxymethylfurfural can be ...
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 ...
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 ...
Mechanochemical Preparation of Novel Polysaccharide-Supported Nb2O5 Catalysts
(MDPI, 2019)
Polysaccharides extracted from natural sources can be used as starting material for the preparation of nanoparticle supported composites. A novel family of bio-nanocomposites was mechanochemically synthesized by using ...
Fe-Containing MOFs as Seeds for the Preparation of Highly Active Fe/Al-SBA-15 Catalysts in the N-Alkylation of Aniline
(MDPI, 2019)
We have successfully incorporated iron species into mesoporous aluminosilicates (AlSBA15) using a simple mechanochemical milling method. The catalysts were characterized by nitrogen physisorption, inductively coupled plasma ...
NH4F Modified Al-SBA-15 Materials for Esterification of Valeric Acid to Alkyl Valerates
(MDPI, 2019)
Al-SBA-15 materials were functionalized by ball milling with several niobium loadings (0.25–1 wt.%) and/or with several F- loadings, using NH4F as a precursor. The catalysts synthesized in this study were characterised by ...
Mechanochemically Synthesized Supported Magnetic Fe-Nanoparticles as Catalysts for Efficient Vanillin Production
(MDPI, 2019)
Magnetically separable nanocatalysts were synthesized by incorporating iron nanoparticles on a mesoporous aluminosilicate (Al-SBA-15) through a mechanochemical grinding pathway in a single step. Noticeably, magnetic features ...
Mechanochemical Synthesis of TiO2 Nanocomposites as Photocatalysts for Benzyl Alcohol Photo-Oxidation
(MDPI, 2016)
TiO2 (anatase phase) has excellent photocatalytic performance and different methods
have been reported to overcome its main limitation of high band gap energy. In this work,
TiO2-magnetically-separable nanocomposites ...
Microwave-Assisted Conversion of Levulinic Acid to γ-Valerolactone Using Low-Loaded Supported Iron Oxide Nanoparticles on Porous Silicates
(MDPI, 2015)
The microwave-assisted conversion of levulinic acid (LA) has been studied
using low-loaded supported Fe-based catalysts on porous silicates. A very simple,
productive, and highly reproducible continuous flow method has ...
Simple Preparation of Novel Metal-Containing Mesoporous Starches
(MDPI, 2013)
Metal-containing mesoporous starches have been synthesized using a simple and
efficient microwave-assisted methodology followed by metal impregnation in the porous
gel network. Final materials exhibited surface areas >60 ...
