Influential Mechanism of Natural Organic Matters with Calcium Ion on the Anion Exchange Membrane Fouling Behavior via xDLVO Theory

Membranes, 2021
The fouling mechanism of the anion exchange membrane (AEM) induced by natural organic matter (NOM) in the absence and presence of calcium ions was systematically investigated via the extended Derjaguin–Landau–Verwey–Overbeek (xDLVO) approach.

Anion exchange membrane design for reserve electrodialysis [PDF]

, 2013
Reverse electrodialysis (RED) is a clean, sustainable technology for the generation of energy from the mixing of solutions with different salinity. The ion exchange membranes are key elements in RED. Especially the study of anion exchange membranes is crucial since limited research has been done specifically for RED.

Anionic Exchange Membrane for Photo-Electrolysis Application [PDF]

Polymers, 2020
Tandem photo-electro-chemical cells composed of an assembly of a solid electrolyte membrane and two low-cost photoelectrodes have been developed to generate green solar fuel from water-splitting. In this regard, an anion-exchange polymer–electrolyte membrane, able to separate H2 evolved at the photocathode from O2 at the photoanode, was investigated in

Operando Electrochemical Formation of Integrated Ni-Fe Oxyhydroxide Anode for Durable Anion Exchange Membrane Water Electrolyzer. [PDF]

Adv Sci (Weinh)
The interfacial stability and activity of Ni‐Fe‐based AEMWE anodes can be directly enhanced by operando voltage‐cycling in a FeOOH‐containing electrolyte. This process simultaneously induces Ni oxidation and Fe incorporation, forming an integrated, porous (Fe, Ni)OOH layer with high conductivity and durability.
