Polymeric Floating Photocatalysts Based on PE/TiO2 Composites for the Removal of Organic Pollutants in Water

Polymeric floating photocatalysts based on polyethylene (PE)/TiO2 compositions were synthesized by in situ ethylene polymerization the presence of a titanium–magnesium catalyst sequential deposition magnesium–aluminum complex and TiCl4 commercial TiO2 P25. The optical band gap PE/TiO2 composites was shown to be 3.1–3.3 eV, which allowed for their use as utilization solar light. photocatalytic activity studied degradation methyl orange (MO) under irradiation with UV light (λmax = 384 nm). containing 20–50 wt.% PE found have an optimum combination between floatability activity. maximum photodegradation rate observed at MO concentration below 5 ppm. polymeric could used repeatedly, but long-term exposure radiation accompanied oxidation polymer.
