Abstract

This study focuses on the removal efficiency of indoor VOCs using nano-TiO₂ photocatalytic materials. A high-precision simulation experimental platform was constructed, with typical VOCs such as benzene and toluene selected as research subjects. Key conditions like light intensity, temperature, and humidity were precisely controlled, and the material's removal capability was monitored in real-time. The experimental results show that under conditions of 5000lux light intensity, 25℃ temperature, and 50% humidity, the material achieved removal rates of up to 85%,80%, and 78% for low-concentration benzene, toluene, and xylene, respectively. A detailed analysis of factors such as particle size and light exposure provides strong evidence for further development of indoor air purification technology.
