Natural Sunlight IR‐Driven Highly Efficient Synthesis of Acetaldehyde From Bioethanol Over Cu/Fe2O3

Angewandte Chemie, EarlyView.
This work reports a Cu/Fe2O3 catalyst for the conversion of bioethanol into valuable acetaldehyde and green hydrogen under both infrared (IR) light and natural sunlight. This IR‐driven system sets a new performance benchmark, with TON and initial TOF enhanced by at least one order of magnitude, enabled by a constructed IR photon‐to‐phonon channel and ...

Ion Transfer During Ionomer Contact Electrification: Binding Affinity Controls Charging

Angewandte Chemie International Edition, EarlyView.
The binding affinity between mobile ions and fixed ionomer groups determines the amount of charge transferred during contact electrification. Ionomers with a series of mobile alkali cations as well as mobile anions establish a clear ordering in charge transfer, where higher interaction strength leads to lower charge transfer.
