摘　　要：本研究以多孔泡沫陶瓷催化材料为研究对象,将经催化剂改性的多孔泡沫陶瓷板置入空气净化设备中,在30 m3环境试验舱中测试了该材料对臭氧的净化效果。实验结果显示,专用于降解臭氧的多孔泡沫陶瓷催化材料在空气净化设备中有较好的净化效果。30立方舱密闭环境内,空气净化设备工作2小时,将臭氧的浓度由0.731 ppm降解到0.02 ppm,催化降解效率为96.90%。对自然衰减和催化氧化实验数据进行线性拟合计算后,可得洁净空气量CADR = 0.8580 m3/min。In this study, catalyst was sprayed on the porous foam ceramic and plated into the air purification equipment. A 30 m3 environmental test chamber was used to test purifying effect of ozone. The experimental results show that the porous foam ceramic catalytic materials have good purification effect on ozone degradation in air purification equipment. In the 30 m3 environmental test chamber, the concentration of ozone was degraded from 0.731 ppm to 0.02 ppm with a 96.90% catalytic degradation efficiency when air purification equipment was working in 2-hour duration. The CADR (clean air delivery rate) is 0.8580 m3/min, which was computed by the linear fitting calculation of natural attenuation and catalytic oxidation experiment data.
