Summary:During this work, the properties of mesoporous titanium oxide were improved by nitrogen and carbon co-doping. The synthesis of C,N-co-doped mesoporous titania was conducted using the in situ via template-guided sol-gel self-assembly method. Chitosan was used as templating agent, but also, to provide the carbon and nitrogen sources for doping. In case of conventional TiO2, F127 was be used as surfactant. All the TiO2 synthesis were Ultrasound (US) assisted, followed by microwaves (MW) thermal treatment, since these processes proved to be time and energy saving. For comparison, conventional thermal treatment was also applied. Some preliminary photodegradation studies were made to investigate whether the conventional and the N, C-co-doped TiO2 are suitable for organic pollutants removal from wastewaters.
