In the presence palladium cometal, an almost complete conversion DPE reached...

The catalytic transfer hydrogenolysis (CTH) of benzyl phenyl ether has been investigated using Pd/Fe₃O₄ as a heterogeneous catalyst and 2-propanol H-donor. After 90 minutes at 240 °C, the cleavage ester C–O bond occurs only reaction route, whereas hydrogenation aromatic ring was not observed.

Lignocellulosic biomasses have a tremendous potential to cover the future demand of bio-based chemicals and materials, breaking down our historical dependence on petroleum resources. The development green chemical technologies, together with appropriate eco-politics, can make decisive contribution cheap effective conversion lignocellulosic feedstocks into sustainable renewable building blocks. In this regard, use an indirect H-source for reducing oxygen content in their derived platform...

The use of lignocellulosic biomasses for the production renewable hydrogen is surely among hot-topic research tasks. In this review, we report on recent advances in catalytic conversion cellulose and its derived C6-C5 sugars (glucose, fructose, xylose) polyols (sorbitol xylitol) into via aqueous phase reforming (APR) reactions. APR processes are considered to be new sustainable routes converting carbohydrate fraction at milder reaction conditions if compared with traditional Particular...

The catalytic conversion of methyl and ethyl levulinates into γ-valerolactone (GVL) by using methanol, ethanol, 2-propanol as the H-donor/solvent, promoted ZrO2 catalyst, is described carried out under both batch gas-flow conditions. Under conditions, was found to be best H-donor molecule, with levulinate giving highest yield in GVL. reactions occurring continuous conditions were much more efficient, also showing excellent yields GVL when EtOH used reducing agent. These experiments clearly...

Catalytic hydrotreatment (HT) is one of the most important refining steps in actual petroleum-based refineries for production fuels and chemicals, it will play also a crucial role development biomass-based refineries. In fact, utilization HT processes upgrading biomass and/or lignocellulosic residues aimed to synthetic chemical intermediates represents reliable strategy reduce both carbon dioxide emissions fossil dependence. At this regard, catalytic oils obtained from either thermochemical...

This review provides an overview of heterogeneous bimetallic Pd-Fe catalysts in the C–C and C–O cleavage platform molecules such as C2–C6 polyols, furfural, phenol derivatives aromatic ethers that are all easily obtainable from renewable cellulose, hemicellulose lignin (the major components lignocellulosic biomasses). The interaction between palladium iron affords sites (ensemble or alloy) were found to be very active several sustainable reactions including hydrogenolysis, catalytic transfer...

"Black mass", namely, the mixture of anodic and cathodic materials arising from mechanical shredding spent Li-ion batteries (LIBs), can be easily converted into an efficient heterogeneous catalyst for selective reductions. Here, we demonstrate a concept showing how LIBs, after appropriate thermal treatments, directly used as catalysts hydrogenation biobased furfural other biomass-derived aldehydes ketones. Yet, approach is general applied to variety substrates under widely different...

Coffee silverskin (CS), the main solid waste produced from coffee industry, has efficiently been used as adsorbent material to remove potential toxic metals (PTMs). In order assess its suitability in water remediation, kinetic adsorption experiments of Cu2+, Zn2+, and Ni2+ ions wastewater were carried out performance was compared with that another well-known spent grounds (SCG). By using CS sorbent material, ion removal follows Cu2+ > Zn2+ equilibrium occurring after about 20 min. The...

In this study, a simple and green protocol to obtain hydrochar high-added value products, mainly 5-hydroxymethylfurfural (5-HMF), furfural (FU), levulinic acid (LA) alkyl levulinates, by using the hydrothermal carbonization (HTC) of orange peel waste (OPW) is presented.
