Abstract

The thin layer of MnO2 nanowires with a three-dimensional (3D) porous network structure is uniformly supported on the surface of cordierite honeycomb ceramic (CHC) monolithic substrate by the in-situ deposition method. A series of characterizations of scanning electron microscopy (SEM), X-ray powder diffraction (XRD) and ZETA potentiometric analyzer were used to determine the optimal preparation conditions. Firstly, the MnO2 prepared in acid medium reveals the most suitable nanowire morphology and crystal structure. Secondly, compared to alumina sol adhesive, the nanocellulose sol adhesive is more favorable to uniformly disperse MnO2 nanowires on CHC surface, due to the strong electrostatic repulsion between nanocellulose sol and MnO2 nanowire. Thirdly, a medium MnO2 adding content in the precipitating solution is more beneficial to form a thin 3D network structure with appropriate pore size distribution on CHC substrate, which allows gas feedstocks or products to freely pass through and fully contact with the active component of MnO2 nanowires.
