Enhanced charge carrier separation of manganese(ii)-doped graphitic carbon nitride: formation of N–Mn bonds through redox reactions

Abstract

High photogenerated charge carrier recombination restricts the photoactivity of graphitic carbon nitride (g-C₃N₄), a promising photocatalyst. Herein, Mn^II doped g-C₃N₄, obtained through redox reactions between urea and a permanganate in an inert gas, exhibits significantly enhanced photoinduced charge carrier separation and photoactivity. This work opens a new avenue for doping of g-C₃N₄.
