Metal-Oxygen Clusters is the first book, providing an overview of the
surface chemistry and catalytic properties of heteropoly oxometalates.
After a brief look at the early knowledge of heteropoly oxometalates,
the book discusses the synthesis, characterization, structure, bulk
properties and stability of these materials. The remainder and the
largest portion of the book explores the properties of these solids as
catalysts in acid-catalyzed and oxidation processes in supported or
unsupported forms.
The book provides an up-to-date review of the methods for synthesizing
heteropoly oxometalates of Keggin structure, techniques from
spectroscopic through electrochemical to elemental analysis for their
characterization and the current information on their structure, bulk
properties and their stabilities at high temperatures and under acid and
alkaline conditions. The book discusses the materials employed as
supports for the title solid and the results of the examination of the
supported materials. Methods for the identification of the nature and
source of the two catalytic functions, the acidic and oxidative
properties, of the heteropoly oxometalates are reviewed and discussed.
The use of both the supported and unsupported heteropoly oxometalates as
catalysts in acidity-requisite processes ranging from methanol
conversion to hydrocarbons to ring-expansion and contraction processes
and in oxidation processes from methane cyclohexane are described and
related to the aforementioned properties.
