Explores the effects of the original concentration of formaldehyde, the concentration of TiO_2 and the outside parameters including the temperature, relative humidity and airflow velocity on the photocatalysis performance by experiments. The results indicate that the eliminating performance of the nanometer material is superior to that of the activated carb...
