20.500.12556/DKUM-90315 Hierarchically porous polyacetylene networks adsorptive photocatalysts for efficient bisphenol a removal from water In this article, we report a series of functionalizedpolyacetylene-type networks formed by chain-growth insertioncoordination polymerization in high internal phase emulsions(HIPEs). All polymerized HIPEs (polyHIPEs) contain a hierarchi-cally structured, 3D-interconnected porous framework consistingof a micro-, meso- and macropore system, resulting in exception-ally high specific surface areas (up to 1055 m2·g−1) and totalporosities of over 95%. The combination of π-conjugated andhierarchically porous structure in one material enabled the use ofthese polyacetylene polyHIPEs as adsorptive photocatalysts for theremoval of chemical contaminants from water. All polyacetylenepolyHIPEs demonstrated high efficiency in the adsorption ofbisphenol A from water (up to 48%) and the subsequentphotocatalytic degradation. Surprisingly, high adsorption capacitydid not affect the photocatalytic efficiency (up to 58%). On the contrary, this dual function seems to be very promising, as somepolyacetylene polyHIPEs almost completely removed bisphenol A from water (97%) through the adsorption-photooxidationmechanism. It also appears that the presence of polar functional side groups in the polyacetylene backbone improves the contact ofthe polyacetylene network with the aqueous bisphenol A solution, which can thus be more easily adsorbed and subsequentlyoxidized, compensating for the lower specific surface area of some networks, namely, 471 and 308 m2·g−1 in the case of 3-ethynylphenol- and 3-ethynylaniline-based polyacetylene polyHIPEs, respectively. polyacetylenes emulsion-templating π-conjugated networks macroporous polymers heterogeneous photocatalysis poliacetilen makroporozni polimeri emulzije heterogena fotokataliza true false true ACS Publications (American Chemical Society) Angleški jezik Slovenski jezik https://pubs.acs.org/doi/epdf/10.1021/acspolymersau.4c00032?ref=article_openPDF © 2024 The Authors.
