제목 | Synthesis of Ordered Mesoporous Molybdenum Dioxide using Nano-Replication Method |
초록 | Transition metal oxides offer a variety of interesting properties such as catalytic, optic, electrochemical, magnetic and so on. Among the transition metal oxides, the molybdenum dioxide (MoO2) have been used as catalyst in industry such as partial methanol oxidation with Fe or Ag for preparation formaldehyde, anode material of lithium-ion battery, isomerization of alkene materials, electrochromic materials. Generally, the MoO2 prepared by thermal evaporation and reduction of MoO3 nano-particle which prepared by de-ionized water and a few drops of a binder. The synthesized MoO2 nanoparticle was low catalytic activation due to the extremely low surface area (<5m2/g). Here, we reported the synthesis method of ordered mesoporous MoO2 for improving the low surface area of the MoO2. This as the nano-replication method used mesoporous silica as template with ordered porosity (2~3nm) and high surface area (>800m2/g). The synthesized mesoporous MoO2 proved to have high surface area(>100m2/g) and ordered porosity by the characterizations of powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), transmission electron microscope (TEM) and N2 adsorption. |
