Significant reduction of harmful compounds in tobacco smoke by the use of titanate nanosheets and nanotubes

摘要

Titanate nanosheets and nanotubes have first been introduced into cigarette filter, a great range of harmful compounds including tar, nicotine, ammonia, hydrogen cyanide, selected carbonyls and phenolic compounds can be reduced efficiently. Recently, titanate nanomaterials have attracted great attentions because of their interesting performances and widespread applications in the photocatalysts,1 dye-sensitized solar cells,2 gas sensors,3 and Li-ion batteries.4 As is well known, titanate
