PURPOSE: A coating manufacturing method of photocatalyst of titanium oxide of P- and N- type is provided, which uses electric energy instead of natural or artificial light irradiating facility and can be made in a compacted facility. The system also can treat rapidly high concentration and large amount of gaseous pollutants by rapid reaction due to the catalyst and maximize reaction efficiency by superposing p- and n- type in multi-layers. CONSTITUTION: The method comprises as follows: (i) prepare titanium oxide coating composition of p type that contain titanium oxide, manganese, lithium, platinum, silver, vanadium pentoxide, tungsten trioxide, bismuth, nickel and cobalt oxide; (ii) prepare titanium oxide coating composition of n type that contain titanium oxide, magnesium, lanthanum or yttrium and carbon.
