Anion Exchange Membranes and Perovskite Oxide Electrocatalysts for Water Electrolysis

Anion Exchange Membranes and Perovskite Oxide Electrocatalysts for Water Electrolysis

This community develops the core components for splitting water into hydrogen and oxygen, focusing on ion-conducting membranes and metal oxide catalysts that operate in alkaline environments.

The research centers on two primary material classes: anion exchange membranes (AEMs) and perovskite oxide electrocatalysts. Membrane work emphasizes polymer chemistry, specifically designing quaternary ammonium groups, poly(aryl piperidinium) backbones, and cross-linked structures to improve hydroxide conductivity and durability. Catalyst work focuses on nickel, cobalt, and iron-based perovskite oxides for the oxygen evolution reaction (OER) and hydrogen evolution reaction (HER). The applications are explicitly named in the titles: alkaline water electrolysis, anion exchange membrane fuel cells, and air batteries. The goal is to enhance electrocatalytic activity and membrane stability for efficient hydrogen production and energy conversion.

The community is most heavily weighted toward nickel research, representing 0.8% of all nickel studies tracked, and oxygen research, representing 0.3% of all oxygen studies. It also contributes to hydrogen, cobalt, and carbon research, though at lower shares.

The community comprises 6,216 papers, published primarily in the Journal of The Electrochemical Society, Journal of Power Sources, and International Journal of Hydrogen Energy.

Recent work continues to focus on improving the durability and mass transport of anion exchange membranes for pure water electrolysis, as well as the design of perovskite-based electrocatalysts for sustainable hydrogen production.
