despite significant progress in the synthesis of nanocomposite materials , integration of several components with various functions remains a big challenge , which significantly limits control over nanocomposite properties . the disclosure provides a multifunctional micro particle based on incorporation of titania nanoparticles combined into a porous polylactic acid matrix . pla is used as a biodegradable and biocompatible polymer and titania nanoparticles represent photocatalytically active nanofillers capable of degradation of organic compounds under solar irradiation . titania nanoparticles are integrated with pla by using ‘ mixed ’ and ‘ in situ grown ’ approaches . the hybrid systems effectively absorbed and degraded organic impurities from water . the sorption capacity , dye degradability , and pla disintegration were controlled by varying the concentration of incorporated titania . the hybrid degradable systems can be applied as novel non - toxic photocatalytic materials for such as environmental cleanup of contaminated waters .
