The photocatalytic cleavage of the C–O bonds between β-O-4 structure in natural lignin is still very challenging. Regrettably, efficiency and selectivity photocatalysts for valorization need to be further improved due fast recombination photogenerated carriers unsuitable redox potential. To address these challenges, an efficient approach promoting one-step Cβ–O bond model compounds by using a g-C3N4/Zn4In2S7 (CN/ZIS) photocatalyst with step-scheme (S-scheme) heterojunction was employed under...
The photocatalytic depolymerization of lignin is a sustainable strategy to produce high-value aromatic chemicals.
Lignin, the second largest component of biomass, is considered as an important alternative source fossil reserves for production fuels and chemicals. Here, we developed a novel method to oxidatively degrade organosolv lignin into value-added four-carbon esters, particularly diethyl maleate (DEM), with cooperative catalyst consisting 1-(3-sulfobutyl) triethylammonium hydrogen sulfate ([BSTEA]HSO4) 1-butyl-3-methylimidazolium ferric chloride ([BMIM]Fe2Cl7). Under optimized conditions (1.00 MPa...
A magnetic silica supported Brønsted acidic ionic liquid is employed in lignin depolymerization into aromatic monomers, such as aryl aldehyde, ketone, acid, and ester.
A KF/<italic>γ</italic>-Al<sub>2</sub>O<sub>3</sub> catalyst is prepared and used in lignin depolymerization into low-molecular weight compounds, such as phenols aliphatic compounds.
The facile, green, and efficient strategy for the separation of lignin from straw subsequent production value-added chemicals is crucial to current utilization straw. Herein, up 23.72% was isolated wheat stalk over cheap green 1-(3-sulfobutyl) triethylammonium hydrogen sulfate ([BSTEA]HSO4) in aqueous ethanol (Vethanol: Vwater = 4:1). acquired verified as a p-hydroxyphenyl-guaiacyl-syringyl type, which had narrower molecular weight distribution, better thermal stability, higher purity...
In order to find a better collector for the separation of carbon and kaolin from coal gangue flotation, explore action mechanism collectors, this paper selected 12 kinds collectors systematic comparison, including five non-polar organics with different chain lengths, polar organic matters double bonds, triple benzene, as well cycloalkyl, ester, carboxyl, aldehyde groups. The flotation results show that longer (with atom number 13~15), effect, effect phenyl group (among four hydrocarbon...
H 6 P 2 W 18 O 62 /γ-Al 3 prepared by supercritical impregnation exhibited excellent catalytic performance.
Silicon (Si) is considered a highly promising anode material for lithium-ion batteries (LIBs), attributing to its suitable working potential and high specific capacity. Nevertheless, the enormous volume expansion during lithiation, poor electron conductivity, low (Li+) diffusion rate limit application of Si anodes. Here, we design novel single carbon layer nanotubes (CNT) coated nanoparticle (Si NP@C@CNT composites), in which derived from citric acid separates between NP), effectively...
Fabricating highly efficient Pd-based nanocatalysts with a well-defined structure is desired for the commercialization of direct ethanol fuel cell (DEFC). Herein, series hierarchical three-dimensional N-doped hollow graphene spheres (NHGS) supported dendritic PdCu alloy catalysts PdxCu(d)-NHGS (x: Cu/Pd theoretical molar ratio 4, 2, and 1) are assembled by one-pot ascorbic acid reduction-immobilization method. Aiming to maximize Pd utilization realize electrooxidation, this novel...
