Selective oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA) is one the key reactions for producing chemical commodities from biomass and their derivatives. The challenge this reaction develop an efficient catalytic process that can be conducted under mild conditions (room temperature atmospheric pressure, using oxygen molecules in air as oxidant) a recyclable catalyst.

The Co-N /C-800-AT was prepared by pyrolysis cobalt phthalocyanine-silica colloid composites subsequent removal silica template nanoparticles. showed extremely high...
Recently, there has been growing interest in the transformation of renewable biomass into value-added chemicals and biofuels.
Selective hydrogenolysis of the Caryl-O bonds in lignin is a key strategy for generation fuels and chemical feedstocks from biomass. Currently, has been mainly conducted using hydrogen, which flammable not sustainable or economical. Herein, an external hydrogen-free process aryl ethers models dioxasolv over nickel nanoparticles supported on Al2O3, reported. Kinetic studies reveal that transfer activity three model compounds decreased following order: benzyl phenyl ether (α-O-4),...
Herein, we report a series of CuPd catalysts for electrochemical hydrogenation (ECH) furfural to 2-methylfuran (MF or FurCH3 where Fur=furyl) in aqueous 0.1 M acetic acid (pH 2.9). The highest faradaic efficiency (FE) MF reached 75 % at -0.58 V vs. reversible hydrogen electrode with an average partial current density 4.5 mA cm-2 . In situ surface-enhanced Raman spectroscopic and kinetic isotopic experiments suggested that electrogenerated adsorbed (Hads ) was involved the reaction...
Abstract Ubiquitous anti‐counterfeiting materials with a rapidly rising annual consumption (over 10 m 2 ) can pose serious environmental burden. Biobased cellulosic birefringence offer attractive sustainable alternatives, but their scalable solvent‐free processing remain challenging. Here, dynamic chemical modification strategy is proposed for multi‐modal melt‐processing of birefringent eco‐friendly anti‐counterfeiting. Relying on the thermal‐activated covalent‐locking spatial topological...
We study the possibility that particle production during inflation could source observable gravity waves on scales relevant for Cosmic Microwave Background experiments. A crucial constraint such scenarios arises because can also inflaton perturbations, and might ruin usual predictions a nearly scale invariant spectrum of Gaussian curvature fluctuations. To minimize this effect, we consider two models in sector is only gravitationally coupled to inflaton. For single instantaneous burst...

Abstract In this study, two poly(acrylic acid)/alumina (PAA/alumina) nanocomposites with varied polymer loadings were prepared via in situ polymerization of preadsorbed acrylic acid. One composite would have a ~1/4‐monolayer coverage, while the other had ~2‐monolayer coverage. The produced materials characterized adsorptive behavior Pb 2+ from aqueous solution. When there was less PAA nanocomposite sample, higher sorption capacity due to potentially blocked alumina pores by formed ....
