摘要：

Efficient application of perovskite or other mixed oxides as electrocatalysts requires fine, chemically and morphologically homogeneous powders. Freeze-drying seems to be the most reliable method for preparation of such powders, but its success depends on several operational factors which include solution composition, rate of freezing, vacuum level and rate of calcination. The effects of several of these factors on the quality of selected electrocatalysts prepared by freeze-drying have been studied in this work.
