Evolution of mesostructures in titania upon template loading and calcination

Different mesostructured titania (TiO2) powders were synthesized via a sol-gel method using amphiphilic triblock copolymer F38 as the structural template. Mesostructural evolution of TiO2 powders depending on template loading and calcination was investigated systematically. Results showed that the polymeric template as well as calcination played an important role in tuning morphology, grain size, crystal phase, mesoporosity and specific surface area of the synthesized mesoporous TiO2.
