Interface‐Enhanced Electrochemical Epoxidation Over a Core‐Shell Nanozeolite TS‐1@Mn‐N‐C Catalyst

Advanced Science, EarlyView.
Core–shell interface of TS‐1@Mn‐N‐C enables in situ generation of high‐concentration H2O2 and its spatially confined activation toward epoxidation‐active η‐Ti‐OOH species, leading to highly efficient and continuous electrochemical epoxidation. The work successfully addresses the key challenge of inefficient mass transfer and slow kinetics caused by ...

Pt‐Regulated Dynamic Cu(0) Regeneration in CuPt Alloy Enables High‐Efficiency Self‐Driven Formaldehyde Fuel Cells for Potassium Formate Production

Advanced Science, EarlyView.
In this work, a Cu30PtX/CF anode material was synthesized to effectively catalyze the electrocatalytic formaldehyde oxidation, and thereby assembled a fuel cell that offered a high open‐circuit potential of 0.94 V and a power density of 34.3 mW cm−2. This work realizes the co‐generation of electrical energy and high‐value‐added chemicals with nearly ...

Magnetic‐Field‐Tuned Spin‐Dependent D‐Band and Bifunctionality in L10‐FeCoPt for Enhanced Methanol Oxidation

Advanced Science, EarlyView.
The d‐band center and bifunctional mechanism jointly regulate the amounts of adsorbed OH* and CO*, thereby enhancing electrocatalytic performance, while the application of an external magnetic field further boosts this performance. ABSTRACT The spin‐dependent electronic structure of transition‐metal alloys plays a key role in tuning the magnetic‐field ...
