Catalytic Wet Peroxide Oxidation of Phenol in Dark With Nanostructured Titania Catalysts: Effect of Exposure of Anatase 001 Plane
A series of nanocrystalline titanium oxide materials with anatase structure was collected by purchasing the commercial products and by solvothermal synthesis. Characterization of these materials by XRD, HRTEM andN2-adsorption-desorption techniques showed that they displayed 10-30 nm crystal size, to...

| Summary: | A series of nanocrystalline titanium oxide materials with anatase structure was collected by purchasing the commercial products and by solvothermal synthesis. Characterization of these materials by XRD, HRTEM andN2-adsorption-desorption techniques showed that they displayed 10-30 nm crystal size, total surface area of 30-150 m2/g and the share of total surface area represented by [001] facets varied in range of 30-65%. The exposed surface of [001] facets in selected TiO2 materials varied in range of 9-94 m2/g. Testing of these materials as catalysts in catalytic wet peroxide oxidation of phenol revealed a stright correlation between therate of phenol mineralization (concversion of TOC) and the value of exposed surface of [001] facets. |
