Low-Cost and Recyclable Photocatalysts: Metal Oxide/Polymer Composites Applied in the Catalytic Breakdown of Dyes

Novel metal oxide/polymer composite photocatalysts prepared by photocuring with common oxide particles (ZnO or CeO2) and acrylic ester monomers have been investigated for the first time. Metal were fully integrated acrylate polymer network based on crosslink of poly ethylene glycol diacrylate (noted below as Poly-PEG) photopolymerization upon mild light source (LED@405 nm) irradiation. The metal/oxide showed excellent performance in photodegradation Acid Black dye (used a benchmark pollutant) an aqueous environment. Indeed, under UV lamp irradiation 60 min, degradation reached 59% 56%, presence 10 wt% ZnO/Poly-PEG 3 CeO2/poly PEG, respectively. Markedly, new reported offered much better over conventional TiO2 photocatalytic material used control (39% using 1 TiO2/poly PEG). In turn, proposed composites further characterized range analytical characterization methods, including swelling test, thermogravimetric analysis (TGA), scanning electron microscopy (SEM), X-ray diffraction (XRD), dynamic mechanical (DMA), UV–visible diffuse reflectance spectroscopy, spin resonance analysis. results that demonstrated water adsorption properties, high-temperature resistance, recyclability, which very suitable wide application line concept green chemistry.
