高变催化剂活性相γ-Fe_3O_4制备方法研究

STUDY OF PREPARATION METHOD ON ACTIVE PHASE OF HIGH_CHANGING CATALYST γ_Fe 3O 4

利用水热氧化法和ＸＲＤ系统地研究了高变催化剂活性相前体γ＿Ｆｅ３Ｏ４的制备条件（如反应温度、ｐＨ值。

Systematically studied in the paper is the effect on the crystal form of the preparing conditions (such as the temperature,pH,precipitating agent,and the composition of the ferric salt solution etc) of the active phase predecessor of high-changing catalyst by means of the water-hot oxidation and XRD.
