Photocatalytic Activity and Sorption Properties of Calcium-Modified Titanium Dioxide

Mesoporous calcium-modified samples of titanium dioxide are synthesized. Their structural, photocatalytic, and sorption properties are studied. The modified samples differ from titanium dioxide in their characteristics and properties: increased specific surface and average pore volume, smaller average pore diameter, and higher photocatalytic and sorption activities toward dyes and dichromate anions.
