摘要：
A novel porphyrin sensitized TiO2/graphene photocatalyst was synthesized via a simple method using TiO2 nanowires, reduced graphene oxide and porphyrin. Reduced graphene oxide sheets are an excellent conductor that can inhibit the charge recombination and enhance the electron-hole separation of modified TiO2 nanowires. Porphyrin sensitized on TiO2 nanowires acts as a sensibilizer to increase the light absorption of the photocatalyst. The composite with a large superficial area shows improved photocatalytic property to decompose methylene blue under visible light irradiation. (C) 2014 Elsevier B.V. All rights reserved.
