Abstract: Five kinds of rare-earth oxidate ultrafine powders were prepared, and the activity of their catalytic esterification was investigated.It is found that the activity of the UFPs is higher than that of the conventional ones.When Y2O3-UFP is used as the catalyst for esterification, the value of acidity of the product almost reached 0.1.It has broad prospects for application.
