Abstract
BaTi4O9 was synthesized at 800°C in its pure form by the polymerizable complex method, which produced a fine powder with a specific surface area of 8.5 m2/g. The photocatalytic activity for NO conversion of BaTi4O9 as well as that of BaTi4O9 impregnated with Ag (i.e. Ag/BaTi4O9) was measured under illumination of ultraviolet (UV) light, and it was compared with the previous results reported for A12O3 and Ag/A12O3 photocatalysts. The BaTi4O9-based photocatalysts showed much superior photocatalytic properties with respect to the conversion of NO.
