In this work, novel titania (TiO2) nanoparticles were designed as a high performance photocatalyst. It was obtained by a simple method of dispersing nanofibrillated cellulose (NFC) onto the surface of titanium tetrachloride (TiCl4), inducing crystallization and removing NFC templates. Under UV light irradiation, The TiO2 nanoparticles displayed excellent photocatalytic activity for the decomposition of methyl orange solution. It was found that TiO2 after calcination had a more efficiency than that before calcination. The optimum calcination temperature for the removal of NFC templates was 300 °C. Methyl orange solution had been remarkably degraded by TiO2 nanoparticles when the mass ratio of TiCl4 and NFC was 12:1. These results indicate that the TiO2 nanopartilces can be easily applied in the field of wastewater treatment.
