Molybdenum trioxide/polyaniline (MoO{sub 3}/PANI) composite was prepared first by ion-exchange reaction between aniline (ANI) and dodecylamine (DDA) which was intercalated precursor, and then was formed under the polymerization of ANI within the interlayer space of MoO{sub 3} at 120 deg. C for 3 d in air. According to powder X-ray diffraction, scanning electron microscopy, thermogravimetric analysis, infrared spectroscopy and electrochemical testing, MoO{sub 3}/PANI composite has layered structure, and its interlayer spacing is 1.127 nm. Moreover, it has high thermal stability with the compound and completes its weight loss at 751.9 deg. C. Electrochemical investigation shows that MoO{sub 3} is the major active substance in the MoO{sub 3}/PANI electrode, and MoO{sub 3}/PANI electrode demonstrates better conductivity and electrochemical activity than pure MoO{sub 3} electrode, attributed to the promotion of Li{sup +} and/or electron transport. In addition, the alternating current impedance proves that if the resistance of MoO{sub 3}/PANI electrode reduces apparently, the electrochemical activity will increase correspondingly, the same as the relationship between the ohmic resistance and the electrical conductivity. - Graphical abstract: Aniline (ANI) monomer was intercalated into the interlayer space of molybdenum trioxide (MoO{sub 3}) and heat-treated at 120 deg. C for 3 d in air, and then polymerized to form layered structure of molybdenum trioxide/polyaniline (MoO{sub 3}/PANI) composite. Its interlayer spacing of MoO{sub 3}/PANI composite is 1.127 nm.
