PURPOSE: A photocatalytic coating composition is provided to prevent a sick house syndrome by removing toxic material generated from a construction material, to extremely reduce exhaustion of toxic gas due to oxidation of construction material. CONSTITUTION: A photocatalytic coating composition is obtained by mixing dissolving anion stone powder by mixing hydrofluoric acid with a mixture in which the anion stone powder and water are mixed, and mixing ammonia solution with the hydrofluoric acid mixture, neutralizing the mixture, and weakly alkalizing the hydrofluoric acid mixture. The anion stone powder is one or more selected from platinum stone, germanium, zeolite, and tourmaline. The stone powder has a particle size of 5,000 mesh or larger. |
