使用热催化材料降解挥发性有机化合物（VOC）是一种新型的空气净化方式。本文采用陶瓷蜂窝（负载含1％Pt的热催化剂）组成催化装置，研究了其在密闭环境舱中降解空气中甲醛和甲苯的特性。结果表明，在25℃条件下，热催化蜂窝装置对甲醛的降解效果显著，对甲苯无明显降解效果；在170℃条件下，装置对甲醛降解效果明显增强，对甲苯也表现一定降解效果。分析表明，提高温度对降解性能的影响主要表现为催化反应速率的增强。
Thermal catalytic oxidation is a new approach for indoor volatile organic compounds （VOC） degradation. In this paper, a catalytic device using honeycomb structure （coated with catalyst containing 1% Pt） was built to study its VOC removal performance in an air tight chamber. The results showed that under 25℃, the removal performance of formaldehyde was significant while that of toluene was insignificant; under 170℃, the removal performance of formaldehyde significantly increased, and it also showed some effects on toluene degradation.
