Axial Boron Coordination Reconstructs Stereostructure of Cu Single‐Atom Nanozymes for Efficient Water‐Phase Chemical Sensing

Angewandte Chemie, EarlyView.
Sun et al. proposed an axial boron coordination strategy to reconstruct the stereostructure of Cu SAzymes and enable them to serve as efficient laccase mimics for high‐throughput smart sensor array detection of phenolic pollutants in water phases. ABSTRACT Developing single‐atom nanozymes with stereoconfigurations is a new paradigm for biomimetic ...

Synergy Between Photon‐to‐Phonon Pathway and Active Lattice Oxygen Enables Efficient and Stable Syngas Synthesis

Angewandte Chemie, EarlyView.
This work reports the design of a multifunctional MnOx support coupled with classic Rh catalytic centers for light‐driven dry reforming of methane. Benefiting from efficient photon‐to‐phonon conversion pathway and a dynamic OL‐OV cycle, the catalyst achieves high syngas production rates and light‐to‐chemical energy efficiency without external heating ...

CO2 as a Redox Shuttle Enables Photocatalytic Dehydrogenative Decarbonylation of Biomass‐Derived Alcohols to Light Alkanes

Angewandte Chemie, EarlyView.
A heterogeneous photocatalytic system has been developed that enables the dehydrogenative decarbonylation of primary alcohols under visible light using highly dispersed oxidic iron sites supported on aryl‐modified graphitic carbon nitride (Fe@f–gC3N4).
