Abstract: The Li/CNTS-TiO2 composite photocatalysts were successfully prepared by sol-gel method and the supported Li/CNTS-TiO2 photocatalysts were obtained by loading Li/CNTS-TiO2 on the surface of polypropylene spheres and were characterized by XRD, SEM and other methods. The photocatalytic degradation efficiency of diesel was investigated under outdoor light conditions by various parameters including amount of catalyst used for load, reaction time and the initial concentration of diesel to optimize conditions for the treatment of marine diesel pollutant by Li/CNTS-TiO2 photocatalyst. A large-scale verification test was carried out with a homemade simulated device that simulated the marine environment under outdoor conditions, and the supported Li/CNTS-TiO2 photocatalyst was obtained by loading 2.0 g Li/CNTS-TiO2 photocatalyst on the surface of two polypropylene spheres. The removal diesel rate of 91.87% was observed at initial diesel concentration of 100 mg/L for 4 h under outdoor light. The supported Li/CNTS-TiO2 photocatalyst was continuously used with good removal effect under the conditions of self-made simulated marine oil pollution device, with the photocatalytic degradation rate of 92.89% for diesel and 99.72% for crude oil, indicating that the supported Li/CNTS-TiO2 photocatalyst is a friendship photocatalyst for treatment of marine diesel pollution.
