title: Intensive visible-light photoactivity of Bi- and Fe-containing pyrochlore nanoparticles.
abstract: Bi-Fe-Nb-O pyrochlore nanoparticles were synthesized by a facile coprecipitation reaction. They exhibit intense visible-light absorption due to a narrow band gap and high visible-light photocatalytic activity for degradation of methyl orange.
