Claim Text:
1. A method for decomposing at least one of organic compound contained in an aqueous solution, comprising: a step a of adding catalyst particles into the aqueous solution; a step b of decomposing the organic compound by irradiating the aqueous solution with light having a wavelength of 200 nanometers or more and 400 nanometers or less while stirring the catalyst particles in the aqueous solution; and a step c of stopping the stirring in the step b, and separating the catalyst particles from the aqueous solution by sedimentation, wherein the catalyst particles are composed only of titanium dioxide particles and zeolite particles, the titanium dioxide particles are adsorbed on outer surfaces of the zeolite particles, the zeolite particles have a silica/alumina molar ratio of 10 or more, and the catalyst particles are contained in the aqueous solution at a concentration of 0.4 grams/liter or more and 16 grams/liter or less.
