One-Step Preparation of Antibacterial Chitin/Zn Composite from Shrimp Shells by Urea-Zn(OAc)2•2H2O Aqueous Solution 10.1039/C8GC00767E 2018-04-11 A one-step method is proposed to prepare chitin/Zn composite from shrimp shells by urea-Zn(OAc)2•2H2O aqueous solution as decalcification, deproteinization, and Zn-introduction solvent. Chitin/Zn composite contained 34.7 wt% zinc, 1.2 wt% calcium carbonate an...
Recent advances in understanding the pseudo-lignin formation in a lignocellulosic biorefinery 10.1039/C8GC00353J 2018-04-10 The formation of lignin-like structures by the degradation primarily of plant polysaccharides has been observed after the severe thermochemical acidic pretreatment of lignocellulosic biomass. These structures were found to be deposited as droplets and microsp...
An inexpensive catalyst, Fe(acac)3, for regio/site-selective acylation of diols and carbohydrates containing a 1,2-cis-diol 10.1039/C8GC00428E 2018-04-10 This work describes the [Fe(acac)3] (acac = acetylacetonate)-catalyzed, regio/site-selective acylation of 1,2- and 1,3-diols and glycosides containing a cis-vicinal diol. The iron(III) catalysts initially formed cyclic dioxolane-type intermediates with substr...
Efficient and Selective Oxidation of Toluene to Benzaldehyde on Manganese Tungstate Nanobars: A Noble Metal-Free Approach 10.1039/C8GC00123E 2018-04-07 Selective production of benzaldehyde, an industrially relevant precursor material, by oxidation of organic pollutant toluene, in a mild environment-friendly green condition, is still a challenging task. Herein, MnWO4 is demonstrated as an efficient catalyst t...
Production of functionalised chitins assisted by fungal lytic polysaccharide monooxygenase 10.1039/C8GC00422F 2018-04-06 The gene CCT67099 from Fusarium fujikuroi was shown to encode a novel enzyme from the Lytic Polysaccharide Monooxygenase (LPMO) Family AA11. The gene was expressed and a truncated version of the enzyme, designated as FfAA11, was purified from the periplasmic ...
Separation of phenolic compounds by centrifugal partition chromatography 10.1039/C8GC00179K 2018-04-06 Phenolic compounds are ubiquitous biomolecules exhibiting a wide range of physiological properties, with application in the pharmaceutical and nutraceutical fields. In this work, aqueous biphasic systems (ABS) formed by polyethylene glycol and sodium polyacry...
Hydrogenolysis of methyl glycolate to ethanol over Pt-Cu/SiO2 single-atom alloy catalyst: a further step from cellulose to ethanol 10.1039/C8GC00309B 2018-04-06 Cellulosic ethanol can be produced via a chemocatalytic approach in which cellulose is first converted into methyl glycolate (MG) in methanol with the promotion of W-based catalyst and oxygen atmosphere, and the formed MG was then hydrogenated to ethanol over...
Increase in hydrogen production from light and ethanol using a dual scale porosity photocatalyst 10.1039/C7GC03508J 2018-04-05 Stable photo-catalytic production of hydrogen is demonstrated under simulated solar irradiation from aqueous solutions of ethanol over a dual porosity 3D TiO2 nanotube array (TNTA). The photocatalytic material consists of a uniform layer of TNTAs grown on eac...
Nitrogen Ligated Nickel-Catalyst Enables Selective Intermolecular Cyclisation of β- and γ-Amino Alcohols with Ketones: Access to Five and Six-member N-Heterocycles 10.1039/C8GC00318A 2018-04-04 Owing to the great demand for synthesis of N-heterocycles, development of new reactions that utilise renewable resources and convert them into key chemicals using non-precious base metal-catalysts is highly desirable. Here we disclosed a sus-tainable Ni-catal...
A sustainable oxidative esterification of thiols with alcohols by a cobalt nanocatalyst supported on doped carbon 10.1039/C8GC00441B 2018-04-04 Here, we developed a new cobalt nanocatalyst supported on N-SiO2-doped activated carbon (Co/N–SiO2–AC), which exhibits excellent catalytic performance towards the oxidative esterification of (hetero)aryl and alkyl thiols with alcohols. A wide array of sulfini...
