Abstract

A composite of g-C3 N4 with visible-light photoactive S-doped carbon was synthesized. Synergistic effects in surface chemistry and electrical conductivity, and a decrease in the band gap (Eg , estimated from optical measurements) from 2.91 eV for g-C3 N4 to 2.79 eV for the composite were found. Both the carbon and the composite showed photosensitivity but only the composite revealed a visible-light-driven reduction activity.

Keywords: composite; graphitic carbon nitride; photoactivity; polymer-derived carbon; surface chemistry.
