Catalyst Ink Preparation Matters for Electrocatalytic Carbon Dioxide Reduction
ChemElectroChem, Volume 12, Issue 6, March 15, 2025.This work studies how catalyst ink affects catalyst layer properties, and consequently how catalyst layer thickness and roughness influence CO2 electroreduction performance: thicker layers favor C2+ products by lowering local CO2 and increasing local pH, while thinner layers enhance C1 products by raising local CO2 and reducing local pH.

Improved Chloride Tolerance of Pt Surface by Ionomer Layer Structure Engineering
ChemSusChem, EarlyView.A hybrid ionomer interface combining cation and anion exchange ionomers effectively suppresses Cl− poisoning of Pt electrocatalysts. In situ inductively coupled plasma‐mass spectrometry measurements reveal a 40% reduction in local Cl− concentration on Pt, attributed to the surface charge distribution of the hybrid ionomer layers. This approach provides
