Three-dimensional network graphene aerogel for enhancing adsorption and visible light photocatalysis of nitrogen-doped TiO_2

摘要

A series of novel N-doped TiO2/graphene aerogel (NTGA) composites were successfully prepared by a chemical reduction self-assembly method. The NTGA composites were characterized by XRD, XPS, SEM and TEM, and their photo-generated electron transfer performance was measured by EIS. All NTGA composites exhibit excellent adsorption property and visible light photocatalytic ability, and the removal rates of Methlyene blue (MB) (20 ppm, 100 ml) reach to more than 90%. In sum, this strategy provides a new thought to enhance the adsorption and photocatalytic performance of N-doped TiO2 (NT). (C) 2018 Elsevier B.V. All rights reserved.
