喷雾热解是一种典型的液相-颗粒转化过程，在高温下，由于液相成核和气相热解，可以形成复杂和高度结晶的氧化物。并且，该方法可以通过向源溶液中添加添加剂来控制颗粒中/上的精细结构。以柠檬酸为添加剂，通过喷雾热解，金属硝酸盐的水溶液液滴可以转化为多孔氧化物颗粒。固体氧化物燃料电池（SOFC）的阴极和阳极需要多孔结构，以获得更大的反应面积和更高的气体扩散率。综述了柠檬酸喷雾热解法制备固体氧化物燃料电池电极颗粒材料的研究进展及其电化学性能评价。
Spray pyrolysis is a typical liquid-to-particle conversion processing, and can form complex and highly crystalline oxides due to nucleation in liquid phase and pyrolysis in gas phase at a high temperature. And, this method can control the fine structure in/on the particles with an additive into the source solution. By the spray pyrolysis with citric acid as the additive, aqueous droplets of metal nitrates can convert to porous oxide particles. The electrode, cathode and anode, of solid oxide fuel cell (SOFC) needs porous structure for larger reaction area and higher gas diffusivity. The synthesis of the particle materials of the SOFC electrodes by the spray pyrolysis method with citric acid and the electrochemical evaluation for SOFC are reviewed.
