Oxidation decomposition reaction of CN- ion was studied using two types of TiO2 photocatalysts and related nitrogen-doped photocatalysts. Although the oxidation products of CN- ion using TiO2 powder consisting 30% rutile and 70% anatase demonstrated CNO-, followed by NO3- and CO32-, the generation of CNO- was inhibited and the formation of molecular nitorogen was detected with TiO2 composed of 100% anatase. Doping nitrogen to TiO2 photocatalysts facilitates their use under visible light irradiation. Particularly, nitrogen-doped anatase type TiO2 photocatalyst oxidized CN- ion to N2 directly, while CNO- formation was greatly suppressed under the irradiation by sunlight. The use of nitrogen-doped anatase type TiO2 photocatalyst under sunlight irradiation is useful as a novel decomposition method for spent CN- solution. Redox potential determination is effective to monitor CN- ion decomposition reaction.
