Catalyst Supports for Energy Conversion Processes
This contribution aims to provide a general overview of the potential of ceramic materials in several areas related to energy production and storage. Ceramic materials for both low and high temperature fuel cells are examined in some detail. Engineered, porous, ceramic support loaded with noble metals are particularly suited to address the material limitations encountered with wash-coated, metal-based, catalyst supports. These materials demonstrated high-performance and resistance under severe operation conditions. Metal oxides and carbides present high stability in a fuel cell environment and acceptable electrical conductivity, but most of them possess a low specific area. In addition, H2 production by water splitting on ceramic oxides of the type ferrites, YSZ and other supported systems will be examined. Finally, a few aspects of the new nanoscale ceramics for batteries of higher storage capacity and storage capacitors will also be presented.
