摘要
研究了液相法制备的纳米SnO2和分子筛封装的纳米SnO2簇（Cluster）的氢还原情况，实验发现，与普＆SnO2微粒相比，纳米SnO2超微粒和分子筛封装的纳米SnO2簇的氢还原起始温度可降低100℃～150℃，氢还原起始表观活化能大小为SnO2微粒＞纳米SnO2微粒＞分子筛封装纳米SnO2簇。
The reaction of hydrogen reduction of nm SnO2 (10 nm) prepared by liquid-phase method and zeolite entrapped nm SnO2 clusters is studied. The reduction temperature of nm SnO2 and nm SnO2 clusters is about 100～150℃ lower than that of common SnO2, and the sequence of Ea of hydrogen reduction is as follows: common SnO2>nm SnO2>nm Sno2 clusters.
