Owing to good chemical stability, high catalytic activity and selectivity for target products as well as long service life, platinum alloy gauzes are irreplaceable catalysts for the synthesis of nitric acid, hydrocyanic acid and other chemicals via the ammonia oxidation process. In this paper, the preparation and processing of platinum alloy catalyst gauzes were briefly summarized from alloying to knitting. And then the mechanism of ammonia oxidation involved in the production of nitric acid and hydrocyanic acid was explored and the recent progress in the reaction-induced surface reconstruction was also introduced. Finally, the future development trends for the catalyst gauzes and ammonia oxidation method were proposed. [ABSTRACT FROM AUTHOR]
