Copper (II) oxide as a morphology directing agent in the hydrothermal crystallization of magnetite
Autor: D. G. Owen, G. B. McGarvey
Publikováno v: Journal of Materials Science. 31:49-53
Magnetite crystals with unique morphological characteristics have been grown from hematite under hydrothermal conditions at 150 and 175 °C in the presence of hydrazine and copper (II) oxide. In the absence of CuO, octahedral crystals of magnetite wi

A Comparative-Study of the Microporosity of the Ammonium and Cesium Salts of 12-Tungstophosphoric, 12-Molybdophosphoric, and 12-Tungstosilicic Acids by Xe129 NMR
Autor: J. L. Bonardet, G. B. Mcgarvey, John B. Moffat, J. Fraissard
Publikováno v: Journal of Catalysis. 151:147-154
The Xe 129 NMR method has been applied to the ammonium and cesium salts of 12-tungstophosphoric, 12-molybdophosphoric, and 12-tungstosilicic acids, as well as to the potassium salt of the first acid. The data obtained provide evidence for the presenc

The interaction of alkaline earth cations with metal-oxygen cluster compounds and the implications for their use as heterogeneous catalysts
Autor: G. B. McGarvey, John B. Moffat
Publikováno v: Catalysis Letters. 16:173-180
The magnesium, calcium, strontium and barium salts of 12-tungstophosphoric and 12-molybdophosphoric acids have been prepared. Evidence of the presence of the Keggin anion (primary structure) was obtained from infrared spectroscopic measurements but p

Observation of nitriles formed in the oxidative dehydrogenation of carboxylic acids over metal-oxygen cluster catalysts
Autor: John B. Moffat, G. B. McGarvey
Publikováno v: Catalysis Letters. 10:41-46
At reaction temperatures of 300–350 °C isobutyronitrile and methacrylonitrile, in addition to the expected products of oxidative dehydrogenation, methacrylic acid, acetone, propene, CO and CO2, are produced from isobutyric acid passed over ammoniu

Microporous Metal—Oxygen Cluster Compounds (Heteropoly Oxometalates)
Autor: K. Carr, J. B. Moffat, J. B. Mcmonagle, J.L. Bonardet, J. Fraissard, G. B. Mcgarvey, M. Seay
Publisher Summary Heteropoly oxometalates (also known as metal-oxygen cluster compounds, MOCC) have been known for more than 150 years. Although another form of oxygen polyanion exists, namely the isopolyanions the heteropoly ions are those that cont

Microporous-Mesoporous Metal-Oxygen Cluster Compounds: Ion Exchange, Structure Retention and the Oxidative Dehydrogenation of Isobutyric Acid
Autor: J. B. Moffat, G. B. McGarvey
Publikováno v: Multifunctional Mesoporous Inorganic Solids ISBN: 9789048142750
Metal-oxygen cluster compounds can be prepared with microporous-mesoporous structures by precipitation of certain of their monovalent cation salts from aqueous solution. Exchange of the cations of these salts can be achieved, although the exchange is
