Full Description
Discover the cutting-edge progress of a promising class of materials significant for use in energy technologies as catalysts
Materials are said to be metastable-phases if they can retain their stability when subjected only to slight disturbances. Materials in metastable-phases can have very different properties from those in a state of equilibrium, and can perform very differently under conditions of experimentation, work, or industrial use. Metastable-phase materials are therefore a promising area of study in a variety of different fields, including cutting-edge industries.
Metastable-Phase Materials constitute a wide-ranging overview of these materials, their properties, and their applications. Beginning with an overall characterization of metastable-phase materials and their normal modes of synthesis, it characterizes the most important branch of metastable-phase materials and reviews a range of catalytic applications. The result is a critical contribution to materials science and catalytic chemistry with potentially far-reaching implications.
Metastable-Phase Materials readers will also find:
Treatment of metastable-phase metal materials, 2D metastable-phase materials, and spin-dependent metastable-phase materials
Detailed discussion of metastable-phase material applications in electrocatalysis, photocatalysis, thermalcatalysis, and more
State-of-the-art technological applications in a myriad of areas
Metastable-Phase Materials are ideal for materials scientists, catalytic chemists, inorganic chemists, photochemists, electrochemists, organic chemists, and the libraries that serve these communities.
