Abstract Catalytic oxidation is an efficient and cost-effective technology to eliminate HCHO, and MnO2 shows excellent performance towards this kind of reactions. In this work, a birnessite type manganese dioxide nanoparticles modified silica-doped titanium dioxide (MnO2@SiO2–TiO2) nanofibrous membranes were successfully synthesized by using an electrospinning technique and liquid phase synthesis. It is found that MnO2@SiO2–TiO2-4 nanofibrous membrane showed the best catalytic activity for HCHO removal. The as-fabricated nanofibrous membranes exhibited good and reversible catalytic oxidation activity towards formaldehyde, and more than 90% of the catalytic performance could remain after 5 testing cycles. The successfully constructed MnO2 nanoparticles decorated soft SiO2–TiO2 nanofibrous membranes, which can be a great promise for effectively solving the problem of environmental remediation.
