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.

A Review of Grain Boundaries: Formation Mechanism, Synthesis Strategy, and Application in Electrocatalysis

EcoEnergy, EarlyView.
An overview of grain boundary engineering in the field of electrocatalysis. ABSTRACT Key electrocatalytic reactions such as HER, OER, ORR, CO2RR, and NRR offer promising routes for storing renewable energy as chemical fuels. However, their widespread application is constrained due to the lack of highly active and stable catalysts. Grain boundaries (GBs)

Design of a Novel CeW/Fe‐TiO2 Catalyst With High Oxygen Vacancy for Enhancing the Reactivity and SO2 Resistance in Low‐Temperature NH3‐SCR Reaction

EcoEnergy, EarlyView.
Fe3+ was introduced into the TiO2 lattice using the hydrothermal method, and low‐valent cations replaced part of Ti4+ to generate oxygen vacancies within the Fe‐Ov‐Ti unit, resulting in CeW/Fe‐TiO2 catalysts with oxygen‐deficient structures. Compared with CeW/TiO2 catalyst, the increase in oxygen vacancy content significantly improved the catalytic ...
