Abstract

Manganese/TiO2 composites are prepared by a solvothermal process starting from the precursors
titanium propoxide and manganese nitrate. The solvothermal processes are driven at temperatures of 140
°C or 180 °C. The formation of anatase as crystalline TiO2-phase was determined by XRD for preparation
conditions at 180 °C. The occurance of crystalline phases in nanometer scale is determined further by
TEM. The prepared manganese/TiO2-composites are further investigated as coating onto viscose textile.
The photocatalytic activity of those composites was determined by degradation of organic dye stuff under
illumination with UV-light. The effect of photocatalytic dye degradation is also investigated in presence
of H2O2. The prepared textile coatings exhibit a high capability for dye decomposition under the chosen
arrangement of investigations. For this reason, the prepared coated textile materials could be of high interest
for industrial applications, for example, as filter material for cleaning waste water from dyeing processes.
