▎ 摘　　要

NOVELTY - The device has an anode and a cathode that are electrically connected to an positive and negative electrodes of a power supply through a lead. A particle electrode is fixed between the anode and the cathode, where the particle electrode is a graphene aerogel conductive particle electrode loaded with iron oxychloride. The particle electrode generates active species when the power supply is electrified to degrade gaseous pollutant in air. The particle electrode has sawtooth-shape cross section. The saw-tooth angle of the particle electrode is 60-120 degrees. USE - Air purifying device. ADVANTAGE - The device can improve the processing capacity of gaseous pollutants, and is suitable for the removal of various gaseous pollutants in the air. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a manufacturing method of air purifying device; and (2) an air purifying method. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of the air purifying device. Air inlet (11) Air outlet (12) Air channel (13) Three-dimensional electrode (14)
