Heterogeneous Single/Dual‐Atom Electrocatalysts in Lithium–Sulfur Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This review summarizes recent advances in single‐atom and dual‐atom electrocatalysts for high‐performance lithium–sulfur batteries. The text systematically covers the classification of catalysts by active metal centers, key synthesis methods, in situ characterization for mechanistic insights, and electrocatalytic mechanisms.

Linear‐Nonlinear‐Linear Sandwich‐Structured Polymer Composites With Metal‐Organic Framework (MOF)‐Enhanced Insulating Layers and Horizontally Oriented Nanotube‐Filled Polarization Layer for High Energy Storage Performance

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A linear‐nonlinear‐linear (LNL) sandwich dielectric film was rationally designed for high energy storage. Its outer linear layers are MOF (ZIF‐8)‐enhanced PEI composites (EZ), and the middle nonlinear layer is an electrospun‐hot‐pressed P(VDF‐HFP)/TNTs composite (PT) with horizontally oriented TNTs.

On the Structure and Redox Behavior of Ni and Cu Single Atoms Supported on Carbon Nitride

Angewandte Chemie, Volume 138, Issue 19, 4 May 2026.
Magnetic and electronic spectroscopies, combined with DFT, establish the MN4 binding site of Ni and Cu single atoms on carbon nitride and elucidate their redox photochemistry. Ni undergoes geometry‐preserving, reversible M2+/M+ cycling, whereas Cu collapses to an irreversible low‐coordinate Cu+ state, suppressing photocatalysis.

Curvature and Microenvironment Regulation Enable Robust Seawater Electrochemical Hydrogen Peroxide Synthesis for On‐Site Marine Aquaculture

Interdisciplinary Materials, EarlyView.
This work designs pentagon‐defect‐enriched interconnected spherical carbon (PD/IS‐C) via curvature and microenvironment co‐engineering for seawater H2O2 electrosynthesis. Curvature modulates electronic structure to boost reactivity, while local alkaline microenvironment repels Cl− for enhanced stability, endowing PD/IS‐C with exceptional catalytic ...

Enhanced CO2 reduction to multi‐carbon products on CuLa bimetallic catalyst

InfoMat, EarlyView.
Electrochemical CO2 reduction offers a promising approach for carbon utilization while is limited by selectivity toward multi‐carbon products. In this work, we developed CuLa catalysts, which significantly improved C2+ selectivity towards around 75% under 200 mA cm−2.
