Abstract
We have studied the effect of heat treatment of titanium dioxide nanopowders prepared by autoclaving peroxo titanic acid gel at 130°C and refluxing it on their structural properties and catalytic activity for methylene blue degradation. Titanic acid precipitated from an aqueous titanyl sulfate solution by ammonia was used as a precursor for the synthesis of the peroxo titanic acid gel. Residual ammonium complexes and peroxide groups, whose concentration was determined by the peroxo titanic acid gel heat treatment procedure, were shown to influence the adsorptive and catalytic properties of the titanium dioxide.
