The present invention provides a new method for decomposing and/or removing hazardous substances using a photocatalytic material. The method of the present invention is sufficiently useful in fields requiring quick decomposition and/or removal of hazardous substances in gas and/or liquid phases. The decomposition method of the present invention using a photocatalytic material enables significantly efficient and rapid decomposition of hazardous substances in gas and/or liquid phases by causing a photocatalytic material to coexist with a dilute hydrogen peroxide solution.

A process for producing a crystalline titanium oxide coating film useful as a photocatalyst, photo-electric converting element, etc. The process is suitable for industrial production and enables the crystalline titanium oxide to be formed in a large amount. A crystalline titanium oxide coating film is produced via the following steps (a-1) and (b): (a-1) a step in which titanium or a titanium alloy is heated under the conditions of any of the following (1) to (3) to thereby form a titanium nitride on the surface of the titanium or titanium alloy: (1) in a nitrogen and/or ammonia gas atmosphere in which an oxygen-trapping agent is present, (2) in an atmosphere filled with nitrogen and/or ammonia gas after the atmospheric gas has been removed by evacuation, and (3) in an atmosphere filled with nitrogen and/or ammonia gas after the atmospheric gas has been removed by evacuation, an oxygen-trapping agent being present in the atmosphere; and (b) a step in which the titanium or titanium alloy obtained in the step (a-1) is immersed in an electrolytic solution containing an inorganic acid and/or organic acid and a voltage is applied thereto to conduct anodizing.

The present invention provides a novel method for treating soil-contaminated water, the method using a photocatalytic material capable of efficiently removing, by light irradiation alone, volatile organic compounds and heavy metals that give rise to soil contamination. The present invention provides a method for treating soil-contaminated water that detoxifies volatile organic compounds contained in soil-contaminated water using a photocatalytic material, the method being characterized by including the steps of (1) subjecting the soil-contaminated water to a gas-liquid separation to obtain a gas phase, and (2) decomposing the volatile organic compounds contained in the gas phase obtained in step (1) using the photocatalytic material. The present invention further provides a method for treating soil-contaminated water using a photocatalytic material to remove heavy metals contained in the soil-contaminated water, the method being characterized by including the steps of (1) subjecting the soil-contaminated water to a gas-liquid separation to obtain a liquid phase, and (2) removing the heavy metals contained in the liquid phase obtained in step (1) using the photocatalytic material.
