The Preparation and Application of PAN Nanofibers Loaded MnO₂ Nano/Microparticles with High Performance of Formaldehyde Decomposition

Abstract:

To enhance the formaldehyde decomposition performance of original MnO₂ powder, the polyacrylonitrile nanofibers loaded with MnO₂ nano/microparticles (denoted as MnO₂/PAN) was prepared via a facile method, which combined the low-temperature liquid phase deposition and electrospinning. With the assistance of electrospinning, MnO₂ nano/microparticles can distribute uniformly on both outside and inside of PAN nanofibers. Such a hybrid nanostructure would effectively enhance the specific surface area, thence facilitating the catalytic decomposition of formaldehyde. As a result, the MnO₂/PAN nanofibers manifest a high-efficiency catalytic capacity of formaldehyde decomposition, with around 44.0% formaldehyde removal rate after 12h (60 °C, pH = 2). In addition, it also shows a better reusability than pure MnO₂ powder.
