8-羟基喹啉铜(II)功能化SBA-15的制备、表征及催化性质

Firstly, copper(Ⅱ)-8-quinolinol ligands were introduced into the channels of 3-aminopropyl functionalized mesoporous SBA-15 ( denoted as APS-SBA-15). Then, the obtained copper(Ⅱ)-8-quinolinol functionalized SBA-15 materials[named as Cu(Ⅱ)-Q-APS-SBA-15] were tested as the catalysts for phenol hydroxylation by using H2O2(30%, mass fraction) as an oxidant. The reaction results indicate that Cu (Ⅱ)-QAPS-SBA-15 was an excellent catalyst for this reaction, and over it a high conversion of phenol and a high selectivity to diphenol could be obtained.
