Available in PDF, EPUB and Kindle. Book excerpt: This study concerns the preparation, the characterization, the catalytic applications and the electrochemical properties of different manganese oxides. Several synthetic strategies were used : i) sol-gel process, ii) hydrothermal methods, iii) preparation methods under ultrasonic irradiation and iv) the polyol process. Highly pure birnessite and cryptomelane have been prepared by the sol-gel process and a plausible formation mechanism for the preparation of these solids is proposed. A fast preparation method for the cryptomelane under ultrasonic irradiation assistance (UL) was also developed. The catalytic activity of these solids was evaluated for the dimethylether (DME) combustion and compared to that of manganese oxides prepared using a facile hydrothermal method (HT) and with the ultrasonic assisted method. The catalytic activity is mainly dominated by the cristalline phase and the preparation method, which follows the order : cryptomelane (UL) > cryptomelane (HT) > cryptomelane (Sol-gel) > birnessite (Sol-gel) > [beta]-MnO2(HT) > [gamma]-MnO2 (HT). Moreover, the catalytic activity of birnessite and cryptomelane towards DME combustion can be enhanced through Ce incorporation via ion exchange and impregnation methods. Birnessite and LiMn2 O4 were also prepared using the polyol process. The two solids display high specific surface areas, respectively 137 and 329 m2 .g- 1 with very small particle sizes. Preliminary electrochemical tests performed with LiMn2O4 show promising results.
