Chapter 7 – Recent Applications of Nanometal Oxide Catalysts in Oxidation Reactions

Abstract

Multifunctionality and versatile catalytic behavior of metal oxides are strongly enhanced by decreasing their particle or crystalline domain size to the nanoscale, providing them new and improved catalytic performances. The focus in early studies was mainly on the effect of size, but it has recently shifted and broadened to the effect of the oxide morphology at this scale. Such a control on size and morphology strongly depends on the precise method followed to prepare these materials. After concisely reviewing the methods used to prepare nanosized oxides with different morphologies, we review recent literature on the application of nanostructured oxide catalysts in several oxidation reactions (CO oxidation, oxidative dehydrogenation, selective oxidation, etc.), with emphasis on the study of the effect of the morphology at the nanoscale, and grouped according to the nature of the main component of the catalyst. From the current knowledge on nanometal oxide catalysts here summarized, the future lines of research in this field are outlined.

Advanced Nanomaterials for Catalysis and Energy

Synthesis, Characterization and Applications

Edited by Vladislav A. Sadykov, Boreskov Institute of Catalysis SB RAS, Novosibirsk, Russia Novosibirsk State University, Novosibirsk, Russia

Advanced Nanomaterials for Catalysis and Energy: Synthesis, Characterization and Applications outlines new approaches to the synthesis of nanomaterials (synthesis in flow conditions, laser electrodispersion of single metals or alloys on carbon or oxide supports, mechanochemistry, sol-gel routes, etc.) to provide systems with a narrow particle size distribution, controlled metal-support interaction and nanocomposites with uniform spatial distribution of domains of different phases, even in dense sintered materials. Methods for characterization of real structure and surface properties of nanomaterials are discussed, including synchrotron radiation diffraction and X-ray photoelectron spectroscopy studies, neutronography, transmission/scanning electron microscopy with elemental analysis, and more.

The book covers the effect of nanosystems' composition, bulk and surface properties, metal-support interaction, particle size and morphology, deposition density, etc. on their functional properties (transport features, catalytic activity and reaction mechanism). Finally, it includes examples of various developed nanostructured solid electrolytes and mixed ionic-electronic conductors as materials in solid oxide fuel cells and asymmetric supported membranes for oxygen and hydrogen separation.
