Visible-light photocatalysis on C-doped ZnO derived from polymer-assisted pyrolysis
C-doped ZnO with large surface area was prepared via F127-assisted pyrolysis at 500 oC and used for visible-light-responsive photocatalytic water purification. The bandstructure of the C-doped ZnO was investigated using valance band XPS and DFT simulation. The C-doped ZnO possessed enhanced 10 absorption to UV and visible light, though it showed lower visible-light-responsive photocatalytic activity than ZnO because of significant recombination of photogenerated charge carriers arisen from overloaded C-dopant and oxygen vacancies.

Abstract

C-doped ZnO with large surface area was prepared via F127-assisted pyrolysis at 500 oC and used for visible-light-responsive photocatalytic water purification. The bandstructure of the C-doped ZnO was investigated using valance band XPS and DFT simulation. The C-doped ZnO possessed enhanced 10 absorption to UV and visible light, though it showed lower visible-light-responsive photocatalytic activity than ZnO because of significant recombination of photogenerated charge carriers arisen from overloaded C-dopant and oxygen vacancies.
