This study proposed a technique to enhance the photocatalytic properties of TiO2 using graphene oxide (GO) and modified Montmorillonite (M-MMT).TiO2/GO/M-MMT nano-heterostructured composites were prepared via hydrothermal and co-precipitation.The photocatalytic performance was evaluated by investigating the photodegradation rate and absorption behavior of methyl orange (MO) under visible light irradiation.

The results showed that TiO2/GO/M-MMT heterojunction exhibited excellent photocatalytic degradation performance, as the degradation amino acid rate of MO was observed to be 99.3% within 150 min.The density of adsorbed MO decreased by 62.

1% after 210 min of dark adsorption using the TiO2/GO/M-MMT composite, which was significantly higher than that achieved using M-MMT, GO/M-MMT, and TiO2/M-MMT.The nano-heterostructure increased the effective interface between TiO2, GO, LANTERN and MMT, which increased the charge transfer ability and prolonged the electron-hole separation time.Therefore, the results of this study can be used to design novel photocatalysts to eradicate environmental pollutants.
