A green approach to efficient conversion of cellulose into hexitols and other lighter alcohols through two steps is reported. In this process, hydrolyzed glucose by acids formed reversibly in situ from hot water, the hydrogenated on Ru/C. Understanding aqueous catalytic systems should lead more fuels chemicals.
In the search of alternative resources to make commodity chemicals and transportation fuels for a low carbon future, lignocellulosic biomass with over 180-billion-ton annual production rate has been identified as promising feedstock.

Following brief introduction structure, major pretreatment methods biomass, conversion three main components, i.e., cellulose, hemicellulose lignin, various compounds are...
Selective activation of chemical bonds in multifunctional oxygenates on solid catalysts is a crucial challenge for sustainable biomass upgrading. Molybdenum carbides and nitrides preferentially activate C═O C–OH over C═C C–C liquid-phase hydrogenation bioderived furfural, leading to highly selective formations furfuryl alcohol (FA) its subsequent hydrogenolysis product (2-methyl furan (2-MF)). We demonstrate that pure-phase α-MoC more active than β-Mo2C γ-Mo2N catalyzing furfural...

Here, we report visible-light-driven amination biomass-derived α-hydroxyl and glucose into using NH3 at 50 °C. Ultrathin CdS nanosheets are identified as efficient stable catalyst, exhibiting order magnitude higher activity towards alanine production lactic acid compared commercial well nanoobjects bearing other morphologies. Its unique catalytic property...
Periodate (PI)-based advanced oxidation process has recently attracted great attention in the water treatment processes. In this study, solar irradiation was used for PI activation to disinfect waterborne bacteria. The PI/solar system could inactivate Escherichia coli below limit of detection (LOD, 10 CFU mL-1) with initial concentrations 1 × 106, 107, and 108 mL-1 within 20, 40, 100 min, respectively. •O2- •OH radicals contributed bacterial disinfection. These reactive attack penetrate cell...
Spontaneous migration of atomic hydrogen species from metal particles to the surface their support, known as spillover, has been claimed play a major role in catalytic processes involving hydrogen. While this phenomenon is well established on reducible oxide supports, its realization much more commonly used non-reducible oxides still challenged. Here we present general strategy enable effective spillover over SiO2 with aid gaseous organic molecules containing carbonyl group. By using...
The female vaginal environment contains diverse microorganisms, and their interactions play significant roles in health disease. Lactobacillus species are the predominant microorganisms healthy women relevant as a barrier to defense against pathogens, including Candida albicans. yeast-to-hyphae transition is believed be determinant of C. albicans pathogenesis. In this study, we investigated effects isolates L. crispatus (seven strains), gasseri (six jensenii (five strains) on growth, hyphal...
Monoclinic zirconia (m-ZrO2) supported Ru, Rh, Pt, and Pd nanoparticles with controlled sizes were prepared examined in glycerol hydrogenolysis to propylene glycol ethylene at similar conversions the kinetic regime. Their activity (normalized per exposed surface metal atom, i.e., turnover rate) selectivity depend sensitively on nature of noble metals their particle size. At a size (ca. 2 nm), Ru exhibited greater rate than Pd, decreased sequence ≫ Rh > Pt by factor about 25 (from 0.035...
Direct oxidation of methane to value-added C1 chemicals (e.g. HCHO and CO) provides a promising way utilize natural gas sources under relatively mild conditions. Such conversions remain, however, key selectivity challenge, resulting from the facile formation undesired fully-oxidized CO2. Here we show that B2O3-based catalysts are selective in direct conversion CO (~94% with HCHO/CO ratio ~1 at 6% conversion) highly stable (over 100 hour time-on-stream operation) conducted fixed-bed reactor...
