METHOD FOR PRODUCING A TITANIUM DIOXIDE COATED CARBON TO IMPROVE PHOTOCATALYST ACTIVATION

摘要

PURPOSE: A manufacturing method of titanium dioxide coated with carbon to improve photocatalytic activity is provided to improve optical catalyst decomposition reaction speed depending on concentration of reactant due to increase of adsorption capacity of a carbonized layer. CONSTITUTION: A manufacturing method of titanium dioxide coated with carbon includes a step for manufacturing a compound by mixing titanium dioxide powder and a carbon precursor of molecular weight 100 ~ 5000, and a step for forming a carbonized layer by heat-treating the compound under supply of inert gas. The compound includes titanium dioxide powder 98 ~ 70 weight% and carbon precursor 2 ~ 30 weight%. The carbon precursor is starch, cellulose, polyvinyl alcohol or hydroxyl propyl cellulose.
