Facile Syntheses of Highly-Oxidized Graphite Fluorides

这一奖项是勒纳博士化学博士后奖学金的起始拨款增量，以支持他在俄勒冈州立大学的研究。勒纳博士研究的重点是通过新的化学路线合成高度氧化的氟化石墨。被检查的合成将不使用元素氟作为氧化剂。取而代之的是，使用强大但方便的氧化剂，如锰(VI)和铬(VI)，以及含有小的、容易插入的离子的溶液，如氟化物或双氟化物。这些反应可以在环境条件下在酸性水溶液中进行。一种变化是使用石墨盐，如稳定的金属氟酸盐或金属氧酸盐阴离子，而不是石墨作为起始材料。用X射线衍射法、四探针导电法、振动能谱和库仑还原等方法研究了氟化石墨的结构、电子和电化学性质。

This award is made as the starter grant increment of Dr. Lerner's Postdoctoral Fellowship in Chemistry Award in support of his research at Oregon State University. The thrust of Dr. Lerner's research is the synthesis of highly oxidized graphite fluorides by novel chemical routes. The synthesis to be examined will not employ elemental fluorine as an oxidant. Instead, powerful, but convenient, oxidants such as Mn(VII) and Cr(VI) in combination with solutions containing small, readily-intercalated ions such as fluoride or bifluoride will be utilized. These reactions can be carried out under ambient conditions in aqueous acid solvents. A variation will be to employ graphite salts such as those of stable fluorometallate or oxometallate anions rather than graphite as a starting material. The structural, electronic and electrochemical properties of the graphite fluorides will be examined by X-ray diffraction, 4-probe conductivity measurements, vibrational spectroscopy and coulometric reduction.
