| To solving the problems of high consumption of Pt, the large filling amount of Pt and high cost, an optimum DEC Pt catalyst system was designed by scientifically and reasonably determine the amounts of precious metals, the metal proportion in the alloy and the diameter of the wire, and also the influence factors on the ammonia oxidation reaction. Using the DEC catalyst system, the content of Pt was significantly reduced. The loss of Pt was reduced to 40%~50% and the cost in the whole catalyst system was reduced to 25%~30%. |
