在微波吸收剂辅助的N2放电中，研究了N2 O在常压下的分解。虽然不使用微波吸收剂不能维持放电，但使用双棒型Zr或W吸收剂可以维持稳定的放电。当微波功率为150- 200 W，棒间距为10 mm时，N_2O的最大转化率≥97%。根据产物的质谱数据和放电光谱的光谱分析，讨论了N_2O在气相中和吸收剂热表面上的分解机理。在最大N2流量为1000 sccm、最大棒间距为10 mm的条件下，采用Zr棒，N2 O中的O原子转化为O2的效果最好。
The decomposition of N2O has been studied in a microwave-absorbent assisted discharge of N2at atmospheric pressure. Although discharge could not be maintained without using microwave absorbents, stable discharge could be maintained by using two rods type of Zr or W absorbents. The maximum conversion of N2O was ≥97% at a microwave power of 150–200W and a distance of 10mm between the rods. The decomposition mechanisms of N2O in the gas phase and on the hot surfaces of absorbents were discussed on the basis of mass spectroscopic data of products and optical spectroscopic analysis of discharge spectra. The best conversion of O atom in N2O into O2was obtained by using Zr rods at the longest distance of 10mm between the rods and the highest high N2flow rate of 1000sccm.
