Facilitating Hydrogen Evolution Reaction Activity in Alkaline Water Electrolysis via Formation of Ni‐Co2P Heterojunction

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Ni‐Co2P synthesized via a co‐sputtering method exhibits enhanced hydrogen evolution reaction (HER) activity. The formation of a heterojunction between Ni and Co2P plays a crucial role in this enhancement. At the Ni‐Co2P junction, water dissociation is significantly promoted, while the Ni sites facilitate efficient hydrogen evolution.

Revealing Structure–Performance Relations in Core‐Shell Catalyst‐Based PEM Water Electrolyzer Anodes with Low Iridium Loading

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Table of Contents The TiO2@IrO2 core–shell architecture ensures high electronic conductivity even at a low iridium content of 10 wt%. The resulting catalyst layer shows significantly higher iridium utilization than a commercial reference, leading to improved PEMWE single‐cell performance at low iridium loading.

Bidentate‐Ligand Molecular Bridge in NiFe‐LDH as a Dynamic Proton Relay and Electronic Modulator to Enhance the Oxygen Evolution Reaction

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
By introducing 4‐chlorobenzoic acid ligands into the interlayer of NiFe‐LDH, the carboxyl and Cl groups on either side are respectively bonded to nearby Fe atoms, yielding a stable Bridge‐Linked structure. The strong electron interaction between the ligands and metal ions suppresses metal ion leaching during the reaction process, thereby maintaining ...

Liquid‐Mediated Kinetically Controlled Synthesis of Porous Carbon with Homogeneous Graphitic Networks for High‐Rate and High‐Loading Organic Supercapacitor

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Liquid‐mediated kinetic control reconstructs a “rigid–flexible” carbon precursor into homogeneously graphitized porous carbon. The resulting porous structure and homogeneous graphitic network accelerate ion/electron transport, enabling superior performance in high‐rate and high‐loading organic supercapacitors.
