Abstract

A visible-light-responsive photocatalyst has been prepared simply by sintering a TiO₂-coated Cu plate. The new photocatalyst was able to reduce the concentration of formaldehyde by 8-12% at ca. 296K with an air flow rate of ca. 0.5 L/min (ca. 1ppm formaldehyde included), a photocatalyst cross section of 50 × 100mm², ca. 50% humidity, and light intensity of 30W/m² (white LED light). The reduction rate was approximately two times higher than that for N-doped TiO₂ (TiO_2-xN _x) under almost the same test conditions.
