摘要
用锐钛矿型纳米TiO2制备了纳米级SO42-/TiO2和S2O82-/TiO2固体超强酸.分析结果显示:纳米级SO42-/TiO2固体超强酸具有较高的酸强度、较大的比表面积、较强的红外光谱特征吸收峰,对乙酸和丁醇的酯化反应有较高的催化活性.
The nanosized SO4^2-/TiO2 and S2O8^2-/TiO2 solid superacids were prepared by anatase titania. The results show that the nanosized SO4^2-/TiO2 solid superacid has stronger acid strengh, biger specific surface area,stronger absorption peaks in FT-IR spectroscopy and higher catalytic activity for the esterification reaction of acetic acid and n-butanol.
