A 3D nitrogen-doped graphene aerogel for enhanced visible-light photocatalytic pollutant degradation and hydrogen evolution

摘要: Three-dimensional (3D) graphene-based aerogels have attracted widespread interest as promising photocatalysts for dye degradation and hydrogen production. Herein, we developed a 3D nitrogen-doped graphene aerogel (3DNG) from graphitic carbon nitride combined with oxide (GO). The nitrogen dopant in the was achieved via thermal treatment at 1000 °C, catalyst could retain its porous structure after treatment. 3DNG characterized FTIR, Raman, TEM, UV-vis, XPS spectroscopies BET analysis, results indicated that this large surface area of 536 m2 g−1 band gap 2.42 eV demonstrated high adsorption capacity enhanced methylene blue production under visible light irradiation. Characterization also identified bonding π–π interactions better charge transfer resulting doping are major reasons photocatalytic performance over catalyst.
