“… 35 , 54 , 55 Due to POM’s high solubility in an aqueous medium, most POM-based electrocatalytic OER studies are done in a homogeneous medium. 35 , 56 , 57 This limits their catalytic study to homogeneous aqueous conditions, which reduces the recyclability of the catalyst as well as the feasibility of the process. There are many approaches studied till now in an effort to heterogenize POMs, increasing their reusability.…”
