Macroporous oxides are often prepared by template method with polymeric spheres, however, these polymeric spheres synthesized by emulsion polymerization using different initiators, most commonly contain S or/and N chemical residues. We have found that these template-originated impurities are not completely removed after thermal treatment of composites at ~ 500 °C, thus, influencing surface acidic properties and photocatalytic performance of the catalysts. The research is focused on the influence of different types of chemical residues left after incomplete polymer elimination on photocatalytic activity.
