Abstract: Currently, the lack of visible light response, small specific surface area, and non-selectivity limit the development of TiO2. In this paper, the black TiO2@MFA with template cavity (TB-TiO2@MFA) was synthesized by one-step pollutant template method. The one-step pollutant template method not only endowed the sample with a large number of oxygen vacancies, but also simultaneously endowed the sample with a wealth of template cavities. The existence of oxygen vacancy improved the electron transfer efficiency and visible light absorption ability, the existence of template cavity improved the contact of TB-TiO2@MFA with ciprofloxacin (Template pollutant). Hence the existence of oxygen vacancy and template cavity together led to the improvement of the photocatalytic performance of TB-TiO2@MFA. The degradation rate of TB-TiO2@MFA to ciprofloxacin is 11.5 times that of TiO2. More importantly, the template cavity endowed the sample with excellent selective degradation ability, the selectivity coefficient of TB-TiO2@MFA to TiO2@MFA was 2.44, and the selectivity coefficient of TB-TiO2 to TiO2 was 2.76. This work had certain reference significance for designing specific functional photocatalytic materials
