研究目的
To prepare photo reactive bionano hybrid materials by immobilizing M. aeruginosa cells onto PAN/TiO2/Ag nanofiber mats and study their synergistic photocatalytic degradation of organic and inorganic pollutants under visible light irradiation.
研究成果
The study successfully demonstrated the synergistic enhancement of photocatalytic activity for the removal of organic and inorganic pollutants using M. aeruginosa-decorated PAN/TiO2/Ag nanofiber mats under visible light irradiation. The approach presents a sustainable strategy for utilizing harmful algae blooms in environmental remediation.
研究不足
The study focused on the photocatalytic degradation under visible light irradiation and did not explore other light conditions. The reusability of the nanofiber mats was tested only for three cycles.
1：Experimental Design and Method Selection:
The study involved the preparation of M. aeruginosa-decorated PAN/TiO2/Ag nanofiber mats and their evaluation for photocatalytic activity under visible light irradiation.
2：Sample Selection and Data Sources:
M. aeruginosa was obtained from Wuhan Hydrobiology Institute of CAS, China. Other materials included PAN, TiO2, AgNO3, and various chemicals for analysis.
3：List of Experimental Equipment and Materials:
Equipment included SEM, TEM, XRD, UV-vis spectrophotometer, and a photochemical reactor. Materials included PAN, TiO2, AgNO3, and M. aeruginosa.
4：Experimental Procedures and Operational Workflow:
The nanofibers were prepared by electrospinning, and M. aeruginosa was immobilized on them. Photocatalytic activity was measured by the degradation of TC and Cr(VI) under visible light.
5：Data Analysis Methods:
The degradation rates were analyzed using kinetics analysis, and the effects of various active species were investigated.
