The results showed photocatalytic efficiency could reach 35,59% at 21 ℃ and 36.39% at 26℃ with 7 photocatalyst filters and 5 UVC lamps, the overall efficiency of formaldehyde removal of 52.37% at 21 ℃, and 56.8% at 26 ℃, By all experimental data can be found that the temperature for the photocatalytic performance is not obvious in the range of this study.展开更多
