Abstract : Traditionally, macroscopic metallic and ceramic screens have been used as catalysts for the controlled decomposition of hydrogen peroxide as applied to monopropellant thrusters, liquid rocket engines, and hybrid rocket systems. Catalyst activity depends on available catalytic surface area; metallic catalyst stability is generally degraded by catalyst oxidation. This paper will discuss new approaches to forming inexpensive, high surface area decomposition catalyst packs for flightweight applications. The paper will specifically discuss analytical methods for the assay of hydrogen peroxide and the precise determination of inhibitor species. The synthesis, characterization, and evaluation of high surface area catalyst beds will be discussed as compared to traditional propulsion catalysts. Finally, the paper will discuss the effects of valence state and cation type of catalyst activity. p1
