Catalytic ozonation of dimethyl phthalate by Ti-MCM-41 in water.

ABSTRACT: A Ti-MCM-41 mesoporous molecular sieve catalyst was prepared by a hydrothermal method. Nitrogen adsorption desorption, XRD, TEM and SEM characterization results showed that the catalyst had a large specific surface area, a regular hexagonal pore structure, and titanium doping was uniformly dispersed in MCM-41 molecular sieves. The amount of titanium doping, reaction temperature, and the initial solution pH had important effects on the catalytic ozonation of dimethyl phthalate (DMP) by Ti-MCM-41. In comparison to ozonation alone and MCM-41/O₃, Ti-MCM-41/O₃ exhibited the most effective degradation and mineralization of DMP, with a Si/Ti ratio of 80, a reaction temperature of 25 °C, and an initial solution pH of 5.4. Ozonation alone, MCM-41/O₃, and Ti-MCM-41/O
