Basic and Applied Research in Materials
Abstract
This report describes the research carried out in two major areas: 1) Materials for Energy Storage and 2) Heterogeneous Catalysis. Materials for Energy Storage: The discovery of new types of solid electrolytes (such as beta alumina, RbAg4I5, copper and silver halides and stabilized zirconia) with large values of ionic conductivity at relatively low temperatures has enhanced the prospect of developing battery systems possessing a high energy storage-to- weight ratio, high power output capability, long life in service, efficiency in charge-discharge characteristics and the capability of being constructed from inexpensive, readily obtainable materials. Heterogeneous Catalysis: a number of the most important heterogeneous catalysts consist of tiny crystallites of metal supported upon a carrier such as silica or alumina. The support leads to a greater metallic surface area per gram of metal and permits use of the catalyst at temperatures up to 500 C without rapid sintering. However, relatively little is known of the exact nature of the crystallites (including the nature of their attachment to the support), the effect of the support upon the catalyst behavior, the effect of the method of catalyst preparation upon catalytic activity. It is the purpose of this project to provide some resolution of these problems.
