Functionalized Lignin Derivatives as Melt‐Spinnable Precursors for Carbon Fiber Production without Stabilization

open access: yesAdvanced Functional Materials, EarlyView.
By turning off hydrogen bonds by bulky ethyl cinnamate ester derivatization, softwood kraft lignin can flow under elevated temperatures, providing tough fiber in the melt for high take‐up speed. Subsequently, lignin ethyl cinnamate derivatives are readily stabilized with only dilute nitric acid leading to direct carbonized fiber with outstanding ...

Atomic Scale Engineering of Multivalence‐State Palladium Photocatalyst for Transfer Hydrogenation with Water as a Proton Source

open access: yesAdvanced Materials, EarlyView.
Photocatalytic transfer hydrogenation is achieved over a multivalence‐state palladium photocatalyst, in which protons generated from photocatalytic water splitting are added to unsaturated double bonds. The operando light‐induced Electron Paramagnetic Resonance (EPR) spectroscopy confirms the synergistic action between Pd single atoms and nanoparticles,
