TiO2-Embedded Biocompatible Hydrogel Production Assisted with Alginate and Polyoxometalate Polyelectrolytes for Photocatalytic Application

The hybrid hydrogel materials meet important social challenges, including the photocatalytic purification of water and bio-medical applications. Here, we demonstrate two scenarios polyacrylamide-TiO2 (PAAm@TiO2) composite design using calcium alginate (Alg-Ca) or Keplerate-type polyoxometalates (POMs) {Mo132} tuning polymer network structure. Calcium molding allowed us to produce polyacrylamide-based beads with an interpenetrating filled TiO2 nanoparticles Alg-Ca@PAAm@TiO2, demonstrating activity towards methyl orange dye bleaching. Contrastingly, in presence POM, biocompatible PAAm@TiO2@Mo132 was produced through photo-polymerization approach (under 365 nm UV light) vitamin B2 as initiator. For both types synthesized hydrogels, thermodynamic compatibility, swelling behavior were studied. influence composition on its structure mesh size evaluated Flory–Rehner equation. proposed synthetic strategies for production can be easily scaled up industrial manufacturing suitable treatment purposes patch medical application.
