The ozone behavior on heated catalytic probe surfaces is examined in gas flow downstream of atmospheric-pressure dielectric barrier discharge ozonizers. Negative and positive variations in the probe voltage as a function of probe heating current enable one to discriminate catalytic dissociation of ozone at low temperatures and catalytic recombination of oxygen radicals at high temperatures, respectively, on the probe surface. The loss coefficient of ozone on the probe surface derived from the amount of heat removed by catalytic dissociation is of the order of $10^{-4}$ , which increases with increasing probe temperature. The probe temperature decrease per ozone concentration by catalytic dissociation of ozone as a measure of measurement sensitivity increases with probe temperature and is measured typically in the range of 0.5–0.8 Kg $^{-1}\text{m}^{3}$ at ozone concentrations of 10 and 17 gm $^{-3}$ , respectively, showing the applicability of a catalytic probe to a simple sensor body.

催化探针上的臭氧行为及其在介质阻挡放电臭氧发生器下游气流中的应用研究

在大气压介质阻挡放电臭氧发生器下游的气流中检查加热催化探针表面上的臭氧行为。作为探头加热电流的函数的探头电压的负变化和正变化使人们能够分别在探头表面区分低温下臭氧的催化解离和高温下氧自由基的催化重组。由催化分解所带走的热量得出的探针表面臭氧损失系数为 $10^{-4}$ ，随着探头温度的升高而增加。作为测量灵敏度的衡量标准，通过臭氧的催化分解，每个臭氧浓度的探头温度会随着探头温度的增加而增加，通常在 0.5–0.8 Kg 的范围内测量 $^{-1}\text{m}^{3}$ 臭氧浓度为 10 和 17 克 $^{-3}$ 分别显示了催化探针对简单传感器主体的适用性。
