Cu2O/Cu Chiral Catalysts for Highly Selective Solar‐Assisted CO2‐to‐CO Electroreduction

Advanced Functional Materials, EarlyView.
To address the poor target‐product selectivity of the eCO2RR, breakthrough approaches based on the chiral‐induced spin selectivity phenomenon enhance the Faradaic efficiency (FE) for target hydrocarbons, such as CO. To induce this spin polarization strategy in Cu2O/Cu catalysts, it is proposed using amine‐based intermediate organic molecules with ...

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

Advanced 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 ...
