“…37 Previously, we constructed pyridine-based PIPs with a robust donor-acceptor structure, which achieved simultaneous photocatalytic reduction of Cr(VI) and oxidation of RhB. 38 Moreover, unlike the conventional semiconductors, PIPs also show excellent adsorption performance, especially for removing ionic contaminants in water, because of the permanent porosity and the strong electrostatic interaction. 39,40 Specifically, Hu et al constructed an imidazolium-based porous ionic polymer, which exhibited a very large surface area and abundant cation sites and hence boasted the highest saturated capacity and an ultrafast removal rate for sulfadimethoxine.…”
