g-C3N4-Loaded Carbon Nanofiber for Efficient Photocatalytic Hydrogen Production

g-C3N4-loaded carbon nanofibers (CNCNF) were obtained via electrostatic spinning and high temperature calcination. Highly crystalline g-C3N4 can be obtained at 800 °C due to the protection of carbon nanofibers. Benefiting from the high conductivity of carbon nanofibers and the high carrier separation efficiency of g-C3N4, CNCNF shows a significantly enhanced photocatalytic hydrogen production activity (7.7-fold more than pristine g-C3N4), also, the mechanism of photocatalytic performance enhancement is discussed.
