  • New insights on the immobilization of TiO[sub]2 on porous silicate supports-an efficient photocatalytic system for decomposition of VOC [Elektronski vir]
    Novak Tušar, Nataša ...
    Air pollution by VOCs (Volatile Organic Compounds) is becoming nowadays a big environmental problem. For air cleaning TiO2 photocatalysis represents one of the very efficient AOP (Advanced Oxidation ... Methods) that can decompose chemically and microbiologically stable VOCs. However, the photocatalytic activity of nanocrystalline TiO2 powder can be significantly suppressed due tothe agglomeration of particles to microsized aggregates, TiO2 poor adsorption characteristics for organic compounds and its relatively low surface area lead to great limitations in exploiting the photocatalyst to the best of its photoefficiency. These problems can be solved by immobilization of nanocrystalline TiO2 on the porous silicate supports. In this work we discuss the advantages of immobilization of TiO2 nanoparticles on ordered and disordered mesoporous silicates as high surface area supports in terms of efficiency of this photocatalytic system for decomposition of VOCs.
