摘要：

Platinized tin oxide (Pt/SnOx) and gold supported on manganese oxide (Au/MnOx) catalysts have been shown to be good CO oxidation catalysts at low temperatures (30-100°C). The performance of these catalysts has been compared by reacting mixtures of CO and OZ and He under similar conditions. The Au/MnOx catalyst is superior to Pt/SnOx catalysts with regard to both activity and decay characteristics under the conditions examined. As expected, Au/MnOx catalysts exhibit greater activity as the reaction gas mixture becomes more oxidizing. © 1991.
