摘要
制备了Cr2O3和Cr（OH）3，用（NH4）2SO4对其活化做成超强酸，并以IR、XPS和正戊烷转化对超强酸进行了表征．结果显示，Cr（OH）3硫酸化后的酸性比硫酸化的Cr2O3强。
The present paper covers the preparation of Cr2O3 and Cr(OH)3 and their transformation into superacids by addition of SO4-·SO42-/Cr2O3 and SO42-/Cr(OH)3 were characterized by means of IR, XPS and the conversion of n-petane. The results showed that the acidity of sulfated Cr(OH)3 is stronger than that of sulfated Cr2O3.
