The development of high-performance air filter has become more and more important to public health. However, it has always been very challenging for developing a multifunctional air filter to simultaneously achieve excellent filtration and antibacterial properties. Herein, a versatile air filter was prepared with loading the reduced graphener and Zinc oxide on the superfine glass fiber with the three-dimensional network structure by in-situ sol-gel process followed by calcination, which aims to achieve synergistic high efficiency air filtration and rapid response to photocatalytic antibacterial under visible light. The air filter showed a three-dimensional network structure based on a rGO/ZnO/s-GF multilayer and exhibited the highest catalytic performance by achieving a 95% degradation effect on Rhodamine B within 2 h and achieving 100% antibacterial inactivation of the Escherichia coli and Staphylococcus aureus within 4 h under visible light when the weight ratio of rGO in rGO/ZnO is 1.6%. The air filtration efficiency can also be maintained at 99% after loading Zno and rGO photocatalytic particles. The spectrum of PL, DRS and ERS indicate that the combination of rGO and ZnO on the s-GF can increase the separation of photo-generated carriers and the specific surface area of the air filter, thereby increasing the photocatalytic response and antibacterial properties of the s-GF air filter under visible light in a short time.

The dataset has been collected through characterization of the prepared material by several instruments and experimental data from the desigend experiments. All the dataset information has been processed through the attached Origin Pro files.
