超声雾化热解法是一种新型的微细粉体制备技术，将其应用于固体氧化物燃料电池（SOFC）反应器金属陶瓷阳极的制备。该方法对于将微米级金属氧化物金属陶瓷粉末固定在YSZ基底上非常有用。粉末呈球形，分散良好，均匀。在Ni/ZrO 2阳极SOFC反应器中研究了甲烷氧化反应。喷雾法制备的Ni/ZrO 2金属陶瓷对甲烷氧化偶联反应（OCM）具有选择性，而普通浆料法制备的Ni/ZrO 2金属陶瓷对CO和CO2的生成具有活性。虽然雾状阳极的负载量比糊状阳极的负载量小100倍，但两种阳极显示出相似的总收率。活性和选择性的变化可能是由于两种制备方法产生的不同形态。
The ultrasonic mist pyrolysis method (mist method), a novel technique for the production of fine powders, is applied to the preparation of cermet anodes for solid oxide fuel cell (SOFC) reactors. This method is very useful for the fixation of micron-scale metal-oxide cermet powders on the YSZ substrate. The powders are spherical, well dispersed and homogeneous. The oxidation of methane was studied in a SOFC reactor with Ni/ZrO2anodes. The Ni/ZrO2cermet prepared by the mist method was selective for the oxidative coupling of methane (OCM), while the Ni/ZrO2cermet prepared by the ordinary paste method was active for CO and CO2formation. Although the supported amount of the mist anode was 100 times less than the supported amount of the paste one, both anodes showed similar total yields. The variations in activity and selectivity may be due to the different morphologies resulting from the two preparation methods.
