Going from Pt to PGM‐free Catalysts: Effects of Ink Compositions on PEM Water Electrolysis

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Optimisation of cathode ink formulations regarding the ratio between catalyst, carbon and binder results in a boost in PEM water electrolysis performance. The optimisation can be transferred from pentlandites to platinum and selenide catalysts, wherein the metal chalcogenides show a stronger performance enhancement.

Monodisperse High‐Entropy Metal Oxide Nanoparticles Encapsulated Within 2D Porous Carbon Sheets for Enhanced Catalytic Activity in Lithium–Sulfur Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study synthesizes monodisperse oxide nanoparticles with abundant ionic vacancies encapsulated in 2D porous carbon sheets via pyrolysis of a high‐entropy precursor, constructing a cross‐scale catalytic interface. It enables Li‐S batteries with a high capacity of 761 mAh g−1 at 3 C and retains 80.44% capacity after 1000 cycles at 1 C.
