本文利用水热氧化法和XRD系统地研究了高变催化剂活性相前体γ-Fe_3O_4晶体的制备条件如反应温度、PH值、沉淀剂及铁盐溶液的组成等因素对晶型的影响。
In this paper, hydrothermal oxidation and XRD were used to systematically study the preparation of γ-Fe_3O_4 precursors such as reaction temperature, pH value, the composition of precipitant and iron salt solution on the crystal structure.
