|Section2= |Section3= |Section7= |Section8= }} Ruthenium(IV) oxide is the inorganic compound with the formula RuO2. This a black solid is the most common oxide of ruthenium. It is widely used as an electrocatalyst for producing chlorine, chlorine oxides, and O2 catalyst is ruthenium(IV) oxide.〔Mills, A. "Heterogeneous redox catalysts for oxygen and chlorine evolution" ''Chem. Sot. Rev.,''1989, ''18'', 285-316. 〕 Like many dioxides, RuO2 adopts the rutile structure.〔Wyckoff, R.W.G.. ''Crystal Structures'', Vol. 1. Interscience, John Wiley & Sons: 1963.〕 ==Preparation== It is usually prepared by oxidation of ruthenium trichloride. Nearly stoichiometric single crystals of RuO2 can be obtained by chemical vapor transport.〔Harald Schäfer, Gerd Schneidereit, Wilfried Gerhardt "Zur Chemie der Platinmetalle. RuO2 Chemischer Transport, Eigenschaften, thermischer Zerfall" ''Z. anorg. allg. Chem.'' 1963, ''319'', 327-336. 〕 Films of RuO2 can be prepared by chemical vapor deposition (CVD) from volatile ruthenium compounds.〔Pizzini, S.; Buzzancae, G.; ''Mat. Res. Bull.'', 1972, ''7'', 449-462.〕 RuO2 can also be prepared through electroplating from a solution of ruthenium trichloride. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ruthenium(IV) oxide」の詳細全文を読む スポンサード リンク
