Relationships between redox properties of polyoxometalates and their effectiveness as oxidation catalysts. Conference Paper uri icon

abstract

  • Regular metal oxide clusters such as the well-known Keggin ions are used as catalysts for a number of industrial processes including the oxidation of methacrolein to methacrylic acid. Studies demonstrate the roles of redox properties, acidity, molecular structure, and catalyst supports on the effectiveness of polyoxometalates (POM) as oxidation catalysts. Scanning tunneling spectroscopy is useful in determining surface redox properties that correlate well with catalytic effectiveness in the oxidation of a wide array of substrates. Several additional techniques for measuring redox properties of POM are under development and will be discussed. These studies have important implications for the synthesis of potentially superior oxidation catalysts and may have predictive value in extending the application of POM as catalysts for a large number of useful oxidation reactions. This is an abstract of a paper presented at the 228th ACS National Meeting (Philadelphia, PA 8/22-26/2004).
