Green synthesis of 2,5-furandicarboxylic acid, one the most important chemical building blocks from biomass, viaoxidation 5-hydroxymethylfurfural has been demonstrated using hydrotalcite-supported gold nanoparticle catalyst in water at 368 K under atmospheric oxygen pressure without addition homogeneous base.
Aqueous-phase dehydration of xylose into furfural was studied in the presence amorphous Nb2O5 with water-compatible Brønsted and Lewis acid sites. determined as a more active selective catalyst for than typical homogeneous catalysts including HCl Sc(OTf)3, converted 93% 48% selectivity toward water at 393 K. No significant loss original catalytic activity observed after Na+-exchange treatment, which indicates that reaction proceeded only on Isotope-labeling experiments using D2O suggested is...
Hydrothermal treatment of NH4[NbO(C2O4)2(H2O)2]·nH2O in water at 448 K for 3 days produced crystalline Nb2O5 with a deformed orthorhombic structure and high surface area (208 m2 g–1). Fourier-transform infrared spectroscopy measurements pyridine adsorption revealed that the catalyst has both densities Brønsted Lewis acid sites can work presence water. One feature is its density water-compatible (0.21 mmol g–1), which much larger than Nb2O5·nH2O (0.03 The was studied as solid formation lactic...
Synthesis of high-value-added chemicals from biomass and/or biomass-derived platform molecules is considered an important strategy to mitigate the global dependency on fossil resources and include renewable in a circular economy. In recent years, synthesis bio-based plastics has received significant attention as potential alternative conventional industrial processes. Thus, lot effort been put into development not only different classes biomonomers but also drop-in chemicals. Amine-derived...
Aerobic oxidation of biomass-derived furfural to furoic acid was studied with an N-heterocyclic carbene as a homogeneous catalyst. Carbene species generated in situ on 1,3-bis(2,4,6-trimethylphenyl) imidazolium chloride strong organic base (1,8-diazabicyclo[5.4.0]undec-7-ene) highly active and selective for the formation dimethyl sulfoxide at 40 °C. This reaction initiates Breslow intermediate between molecule subsequent activation molecular O2. While catalyst promoted dimerization afford...
Supported molybdenum oxide (MoOx) and tungsten (WOx) materials are a vital class of solid acid catalysts for the chemical industry because their nontoxic nature, strong acidity, remarkable stability in water, hydrogen, oxygen atmospheres, excellent reusability performance. These fascinating acids play pivotal role developing sustainable catalytic routes renewable biomass processing to produce value-added fuels, chemicals, platform molecules. The coordination chemistry MoOx WOx on support...
A photocatalytic, green, and cost-effective approach is the most promising pathway for transformation of sustainable plastic waste, poly(lactic) acid (PLA). However, PLA degrades into carbon dioxide water. This degradation process slow problematic, as it emits CO2, causing global warming effects. Consequently, there an urgent need to develop innovative strategies upcycling lanthanide amino protein formation. Therefore, we report formation ultraresponsive donor–acceptor coupled system, i.e.,...
Abstract Utilizing a catalytic approach for producing biodiesel from non‐edible oils holds promise as solution the next generation of fuels. Therefore, emerging research on replacing conventional catalysts and developing new waste‐derived heterogeneous with acid–base properties in intensified production process aims to achieve significant scientific outcomes including low‐cost biorefinery mitigating increasing energy demand. Hence, prospective replacement green renewable solid acid over or...
Plastic waste, particularly the dominant polyolefins, presents a growing environmental issue due to its chemical stability and low recycling rates. Although various methods are proposed address plastic strong carbon–carbon bonds within as well degradation of mechanical strength additional value by conventional methods, pose great challenges their downstream usage. With this regard, paper emphasizes polyolefins into renewable resources, including carbon materials, liquid fuels, hydrocarbon...
The carbon-catalyzed reaction of Cl2 and CO constitutes the most important industrial route to phosgene. Although defects in carbon lead surface chemical reactions, direct polarization C-heteroatom bonds induces a more successful catalytic activation, rate-determining step overall cycle. interplay between electron-donating -withdrawing ability incorporated nitrogen substituents on formation stabilization active sites was examined by X-ray photoelectron Raman spectroscopy. Mechanistic studies...
