摘要
Visual evidence of the direct, lateral and remote photocatalytic destruction of soot by a thick film titania is provided via a series of simple experiments. The results provide strong evidence for the photogeneration of an oxidising species which is both surface mobile and capable of air-borne diffusion. (C) 2004 Elsevier B.V. All rights reserved.
