摘要：
SO42-/ZrO2-titania nanotubes-X (SO42-/ZrO2-TNTs-X: X of Ti/Zr) solid superacid catalysts with different atom ratios (Ti/Zr) were successfully prepared. The SO42-/ZrO2-TNTs-2 (Ti/Zr of 2) have a specific surface area of 394 m(2)/g and an acid intensity of 1.839 mmol/g. The SO42-/ZrO2-TNTs-2 show excellent selectivity (p/o of 3.34) and activity (yield of 98%) in the selective mononitration of toluene. Importantly, the SO42-/ZrO2-TNTs-2 can be efficiently recycled and regenerated by simple sulfuric acid soaking. (C) 2011 Elsevier B.V. All rights reserved.
