Synthesis of Nanostructured Catalysts & Catalytic Supportsporosity, surface reactivity, and defect chemistry associated with the gas-phase condensation method, sol-gel processing, and pillaring of layered structures are described. The nanostructured catalytic systems not only provide structural tailoring capabilities, but also facilitate understanding of r

Formation of Magnetic Spinel Iron Oxide in Solutioneity and the particle size of spinel Fe(III)-Fe(II) oxide obtained from solution. Electron mobility between Fe(II)-Fe(III) ions is the driving force for crystallization. The growth of surface area is controlled by the interfacial tension of the solid, which depends on pH and ionic strength.

Formation and Phase Analysis of Surface Oxides on Ultrafine Particles of Fe particles they are oxidized in the evaporation chamber by inlet of atmospheric air. Two specimens are presented, A and B. In A the oxidation was slow and in B, a slow initial oxidation was followed by fast oxidation, making the particles glow. TEM micrographs showed, in both cases, a particle struc
