Integration of High‐p, Low‐T CO2 Electrolysis with Pressure Swing Adsorption Purification

Chemie Ingenieur Technik, EarlyView.
We evaluate a high‐p low‐T CO2 electrolysis (LTCE) cell with a pressure swing adsorption (PSA) to compare cascade vs. recycle operation. Although a cascade yields high CO selectivity but limited yield, a full recycle achieves near‐quantitative CO production, highlighting gas recycling as essential for LTCE/PSA systems.

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.

Operando Monitoring Interfacial pH Gradients and Ion Kinetics in Proton‐Coupled Electron Transfer Reactions through Dual‐Loop Electrochemical Methodology

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
We present a dual‐loop methodology for real‐time mapping of interfacial pH that distinguishes electric field effects from changes in proton activity. This universal tool reveals significant pH gradients and identifies ion mobility and buffer capacity as key regulators, providing crucial insights for optimizing electrocatalyst performance in energy ...
