Benign-by-design preparation of iron oxides/humins catalytic nanocomposites
(Royal Society of Chemistry, 2017)
The current acid-catalyzed conversion of biomass feedstocks yields substantial quantities of undesired by-products called humins, for which applications are yet to be found. This work aims to provide a starting point for ...
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 ...
Microwave-assisted valorization of pig bristles: towards visible light photocatalytic chalcocite composite
(Royal Society of Chemistry, 2018)
Waste valorization for the production of valuable materials is of great importance for sustainable development. Herein, a new green methodology for the synthesis of photocatalytically active copper sulfide (Cu2S) carbon ...
Wheat bran valorisation: Towards photocatalytic nanomaterials for benzyl alcohol photo-oxidation
(Elsevier, 2017)
In this work, we have successfully synthesized a set of titania photocatalytic nanocomposites by the
incorporation of different TiO2 content on wheat bran residues. The obtained catalysts were characterized
by different ...
Mild ultrasound-assisted synthesis of TiO2 supported on magnetic nanocomposites for selective photo-oxidation of benzyl alcohol
(Elsevier, 2016)
A simple and effective ultrasound-assisted wet impregnation method was developed for the
preparation of magnetically separable TiO2/maghemite-silica photo-active nanocomposites. The
resulting nanomaterials were characterized ...
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. ...
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 ...
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 ...
