Bi2MoO6 microtubes: Controlled fabrication by using electrospun polyacrylonitrile microfibers as template and their enhanced visible light photocatalytic activity

► Controllable fabricated Bi2MoO6 microtubes by a two-step fabrication route. ► Bi2MoO6 microtubes exhibited enhanced photocatalytic activity. ► The crystal structure and morphology of Bi2MoO6 microtubes strongly depended on the calcination temperature. ► A general way to fabricate other tubes structures of Bi(III)-containing oxides.
