Morpholinium?Modified, Polyketone?Based Anion Exchange Membranes for Water Electrolysis

Water electrolysis is by far the most appealing method to produce green hydrogen. Among possible technologies, Anion Exchange Membrane (AEM) water electrolyzers are promising in medium term, as they make it avoid critical and noble materials catalyst components. However, AEMs still lacking performance stability, which has become current research focus. Here, we report facile inexpensive chemical modification of polyketone (PK) with a functional unit encompassing morpholinium positively charged group, fabrication self-standing membranes. The synthesis products investigated an ensemble physico-chemical spectroscopic techniques, including solid-state time-domain NMR, FT-IR, thermal analysis. membranes show good Ion Capacity values range 1.48–2.24 mmol g?1. A preliminary test shows that PK-based membrane comparable commercial one.
