摘要：

A comparison between two of the best performing photocatalysts in a series of nitrogen- and sulfur-doped titania visible light photocatalysts prepared by atmospheric pressure (AP)CVD is made against a sample of pure undoped titania. This study compares the ability of the samples to photo-oxidize stearic acid and kill Escherichia coli bacteria using white light sources commonly found in UK hospitals. It is shown that both nitrogen- and sulfur-doped photocatalysts are bioactive with extraordinarily similar properties though the nitrogen-doped samples are found to perform very slightly better than the sulfur-doped samples. These materials are suggested for use as anti-microbial surfaces in healthcare environments and as self-cleaning glass.
