摘要: Herein, we demonstrated that an efficient TiO2 visible-light photocatalyst can be fabricated by templating mesoporous polydopamine (PDA) nanotubes. Because PDA is a nitrogen-doped carbon source, nanotubes as templates elicited distinct advantages for obtained TiO2. First, they introduced codopant of and nitrogen into anatase narrowed its band gap. Second, could graphitized in optimized calcination process to form graphene-like layers on surfaces with high conductivity, which assisted the separation photogenerated electron–holes These features endow TiO2@C-PDA (400-2) excellent photocatalytic performance degradation methyl orange under irradiation (>420 nm).
