Ether‐Free Alkaline Polyelectrolytes for Water Electrolyzers: Recent Advances and Perspectives

Angewandte Chemie International Edition, Год журнала: 2024, Номер unknown

Опубликована: Ноя. 1, 2024

Anion exchange membrane (AEM) water electrolyzers (AEMWEs) have attracted great interest for their potential as sustainable, environmentally friendly, low-cost sources of renewable energy. Alkaline polyelectrolytes play a crucial role in AEMWEs, determining performance and longevity. Because heteroatom-containing polymers been shown to poor durability alkaline conditions, this review focuses on ether-free polyelectrolytes, which are more chemically stable. The merits, weaknesses, challenges preparing AEMs summarized highlighted. evaluation synthesis methods polymers, modification strategies, cationic stability will provide insights valuable the structural design future polyelectrolytes. Moreover, situ degradation mechanisms ionomers during AEMWE operation revealed. This provides into AEMWEs accelerate widespread commercialization.

Comprehensive Chlorine Suppression: Advances in Materials and System Technologies for Direct Seawater Electrolysis

Nano-Micro Letters, Год журнала: 2025, Номер 17(1)

Опубликована: Янв. 22, 2025

Abstract Seawater electrolysis offers a promising pathway to generate green hydrogen, which is crucial for the net-zero emission targets. Indirect seawater severely limited by high energy demands and system complexity, while direct bypasses pre-treatment, offering simpler more cost-effective solution. However, chlorine evolution reaction impurities in lead severe corrosion hinder electrolysis’s efficiency. Herein, we review recent advances rational design of chlorine-suppressive catalysts integrated systems architectures chloride-induced corrosion, with simultaneous enhancement Faradaic efficiency reduction cost. Furthermore, directions are proposed durable efficient systems. This provides perspectives toward sustainable conversion environmental protection.
