Nanoparticles of Bi 2 Ti 2 O 7 pyrochlore were synthesized by a coprecipitation method. They exhibit a high visible‐light photoactivity for decolorization of a methyl‐orange dye solution in the presence of a sacrificial agent, H 2 O 2 . The same pyrochlore system with an Ag co‐catalyst showed even faster kinetics under only visible light and an unprecedentedly high photoactivity in the UV range.
