Sulfonated polyindole coated magnetic zincoxysulfide (Ni@ZnO0.6S0.4@SPID) core/shell nanocatalyst for simultaneous photocatalytic H2 production and BPA degradation

Polyindole and polypyrrole as a sustainable platform for environmental remediation and sensor applications

“…Polyindole (PIN), a rising conducting polymer, is being explored and developed as a possible candidate for electrochromic devices 33,34 , sensors 35,36 , photocatalysis 37,38 , and electrocatalysis 39 , anticorrosion 40,41 , diodes 42,43 , supercapacitors 44,45 , batteries, and biology-related applications [45][46][47] . The studies on PIN has been started as early as 1976, Youmans, H. L et.al synthesised polyindole from indole through chemical polymerization 48 .…”

“…The hole will be redistributed on one side of the heterojunction (g-C3N4), and Please do not adjust margins Please do not adjust margins electrons on the opposite side (PPY) which demonstrates a steady internal electric field. Recently, simultaneous H2 production and degradation of organic pollutants have been attained using various visiblelight-driven (VLD) photocatalyst systems based on CPs 37 . A typical example is the generation of photocatalytic hydrogen and Bisphenol A (BPA) removal using photocatalyst based on sulfonated PIN (SPID) coated with magnetic zinc oxysulfide in Na2S/Na2SO3 solution 37 .…”

Impressively, the best approach for H 2 production could be evidenced later in 180 min by employing a BPA solution of 60 mg L −1 concentration.…”

Sulfonated polyHIPE/nanoclay composites with hierarchically porous structure for efficient removal of endocrine‐disrupting hormone from aqueous solution

“…Bisphenol A [2, 2‐bis(4‐hydroxyphenyl)‐propane, BPA] has been recognized as one of the toxic contaminants, as it can mimic the biological activity through interfering metabolic processes of natural hormones, causing serious threat to animals and humans (Ahsan, Islam, Imam et al, 2018). BPA is generally applied as a monomer in the synthesis of epoxy resins, polycarbonates, and it was reported that nearly 3 million tons of BPA are comprised from these industries in a year (Ali et al, 2020; Salehinia et al, 2016). The improper discharge of wastewater effluents including BPA and its derivatives induces contamination of surface and ground waters and even at very low doses (below 10 −3 ppb) can cause birth defects, carcinogenesis, and other disorder (Shi et al, 2022; Wu et al, 2022).…”
