Book excerpt: Transition metal oxides are receiving a great deal of attention because the materials produced are showing promise in the fields of catalysis and electrochemistry. These materials are being produced in a variety of ways, but the low temperature hydrothermal method is producing materials with desired structural characteristics. This study discusses efforts in mild reaction conditions of heat temperatures ranging between 160 and 200 deg C. The factors of pH, reaction time, reaction temperature, and the presence of organic templating cations are also studied to see their impact on traditional and microwave reactions. The relatively new field of microwave synthesis has shown that materials which customarily took 2 days of reaction time in the traditional ovens are reproducible in 30-60 minutes via the microwave ovens. The influence of the organic cations in the reaction mediums is the focus of this particular study. The ability to produce layered vanadium oxides in the absence of such templating cations as TMA would make the materials potentially better for electrochemical purposes. This research used a variety of solvents in an attempt to produce interlayer bridging by organic anions. The solvents of ethylene glycol and acetic acid act as those bridges, each with 2 accessible oxygens.
