Electrochemical Depolymerization of Lignin in a Biomass‐based Solvent

Breaking down lignin into smaller units is the key to generate high value-added products. Nevertheless, dissolving this complex plant polyphenol in an environment-friendly way is often a challenge. Levulinic acid, which is formed during the hydrothermal processing of lignocellulosic biomass, has been shown to efficiently dissolve lignin. Herein, we...

Water Oxidation Catalyzed by a Bioinspired Tetranuclear Manganese Complex: Mechanistic Study and Prediction

DFT calculations were utilized to elucidate the water oxidation mechanism catalyzed by polyanionic tetramanganese complex a [Mn III 3 Mn IV O 3 (CH 3 COO) 3 (A-α-SiW 9 O 34 )] 6 - . Theoretical results indicate that catalytic active species 1 (Mn 4 III,III,IV,IV ) is formed after O 2 formation in the first turnover. From ...

CO2/N2 Separation on Highly Selective Carbon Nanofibers Investigated by Dynamic Gas Adsorption

CO2 separation: Dynamic gas adsorption makes it possible to study the adsorption of gas mixtures and analyze the separation of gases under conditions close to application. With this method, polyacrylonitrile-based carbon nanofibers are assessed as adsorbent for carbon capture. Unlike other carbon materials, they exhibit an excellent CO2/N2 selectivity...

Efficient Metal‐Oriented Electrodeposition of a Co‐Based Metal‐Organic Framework with Superior Capacitive Performance

Co-MOF it: An efficient metal-oriented cathodic electrodeposition method is developed for coating Co-MOF on carbon fiber cloth (CFC), which is realized by using a highly active Co metal surface modifier that enables nucleation and growth of Co-MOF in 3D rodlike crystal bundles. As a binder-free electrode for supercapacitors, Co-MOF/CFC shows high areal...

Electrochemical Oxidation of HMF via Hydrogen Atom Transfer and Hydride Transfer on NiOOH and the Impact of NiOOH Composition

Two paths diverged: Alcohol and aldehyde oxidation on NiOOH is achieved through two mechanisms. One involves chemical hydrogen atom transfer to Ni3+ sites while the other involves electrochemical hydride transfer to Ni4+ sites. It is examined how these pathways impact the oxidation of HMF and its oxidative intermediates, which functional group of HMF...

Highly Selective Photocatalytic Aerobic Oxidation of Methane to Oxygenates with Water over W‐doped TiO2

Not too radical: Low-cost and highly effective W-doped TiO2 photocatalysts are prepared to achieve the photocatalytic oxidation of methane with O2 under mild conditions. The increased separation of photogenerated carriers promotes the photocatalytic activity. The upshifted band structure prohibits the over-generation of hydroxyl radicals (⋅OH) to decrease...

Fine‐tuning of siloxane pendant distance for achieving highly efficient eco‐friendly nonfullerene solar cells

Side chain engineering has been proved to show profound impact on polymer properties and blend morphology. Herein, the critical role of siloxane-terminated alkoxy side chains was revealed by a tiny decorating method that the molar content of siloxane-terminated alkoxy side chain was fixed to 5% and its alkyl linker was the only tuning factor. The sequent...
