3D‐Printed Metal‐Supported MOF‐Heteropoly Acid Nanozyme for High‐Performance Peroxidase‐Mimic Activity and Ultra‐Sensitive Glucose Detection

Advanced Science, EarlyView.
A hierarchically structured Fe‐BTC‐PMA immobilized 3D‐printed platform is engineered as a robust artificial enzyme for colorimetric glucose sensing. The hybrid architecture efficiently activates H2O2 to drive TMB oxidation. This integrated system enables sensitive, reusable, and scalable detection with enhanced catalytic stability and analytical ...

Reinforcing Oxygen Activation of Spinel Oxide via Mn─O Covalency Engineering for VOCs Oxidation

Advanced Science, EarlyView.
A MnCo spinel catalyst with weakened Mn─O covalency was synthesized via a hard‐template method. The reduced Mn─O covalency facilitates localized electron redistribution, promoting the activation of both molecular oxygen and lattice oxygen, and thereby enabling the efficient and complete oxidation of VOCs (ethyl acetate, toluene, and propane).

Atomic Interlayer Mo–N4 Sites Enable Rapid Charge Transfer and Efficient CO2 Photoreduction

Advanced Science, EarlyView.
This work achieved efficient CO2 activation and ultrafast interlayer electron transport in a 2D COF by constructing atomic‐level Mo‐N4‐induced interlayer electron bridges (IEB), thereby kinetically and thermodynamically co‐driving the photocatalytic coupling of CO2 reduction with 4‐methoxybenzyl alcohol oxidation.
