PROBLEM TO BE SOLVED: To improve the function of a TiO2 photocatalyst used for an environmental pollution process to an implementation level by radiating pulse ultraviolet rays in a magnetic field to an electric double-layer control catalyst film arranged between solenoid couples. SOLUTION: An electric double-layer control catalyst film in a loop or a cylinder of a P or N-photoconductor arranged in the pulse magnetic field by upper and lower solenoid couples 1 with a P-N junction device is electromagnetically induced and polarized into an excited state. Pulse UVR 3 are radiated to it, photoelectrons are expelled to control positive holes, the desorbed photoelectrons are bonded to the hydrogen in the air or are arrested by emitters or Pt on both sides of an insulator. Amorphous anatase is vacuum-deposited or sputtered on a quartz-reinforced plastic short-fiber sheet to form an electric double-layer control catalyst film 2 serving as a photodesorption electron pump. A satisfactory oxidation reduction process is realized accordingly.
