Abstract	The use of ceramics as heterogeneous catalysts represents an extension of “non-traditional” ceramics applications and is now a burgeoning topic of research. In this Review, the principles of heterogeneous catalysis are presented and discussed in terms of surface reactivity and catalyst structure in general. Catalytic selectivity, rate enhancement and catalyst deactivation are addressed. The critical (bulk and surface) structural features that impact on catalyst performance are identified along with a survey of catalyst characterization techniques. Ceramics applications in catalysis are divided into (i) direct use as catalysts and (ii) use as support materials (substrates) to anchor and disperse a variety of active metals. Practical ceramic catalysts are typically complex metal oxides containing at least two different cations which offer enormous compositional flexibility, as is discussed in the case of perovskite oxides. Taking a broad definition of ceramics as “any inorganic nonmetallic material,” there is a wide array of catalysts that can be termed ceramics with disparate end uses. For the purposes of illustration, three established systems are discussed that each illustrates the role of ceramic materials in practical heterogeneous catalysis: (i) catalysis using zeolites; (ii) catalytic converters; (iii) solid oxide fuel cells.
