With the continuous improvement in medical science in modern times, the spread of bacterial infection has become a matterof global concern. Therefore, the search for biological medical materials with antibacterial function has become a focusof intense research. In this work, pure SnO2 and Ag-doped SnO2 hollow nanofbers were fabricated by a combination of anelectrospinning method and a calcination procedure, and the Effects of the doped Ag on antibacterial activity and catalyticantibacterial activity were subsequently investigated. Through the process of high-temperature calcination, a high heatingrate would lead to the formation of a hollow tubular structure in SnO2 fbers, and Ag2O would be reduced to Ag0by a facileprocess with appropriate thermal treatment. Additionally, the existence of SnO2 as a tetragonal rutile structure was confrmed. On the basis of pure SnO2, doping with Ag greatly improved the antibacterial activity and catalytic antibacterial activity ofhollow nanofbers. The formation mechanism and the antibacterial mechanism of pure SnO2 and Ag-doped hollow nanofbersare also discussed. This study has broad application prospects for biological medicine.
