摘　　要：利用3-氨丙基功能化的介孔SBA-15(APS-SBA-15)作为载体,通过C—N共价键将8-羟基喹啉铜(Ⅱ)固定到APS-SBA-15孔道中,制备了8-羟基喹啉铜(Ⅱ)功能化的SBA-15催化剂[Cu(Ⅱ)-Q-APS-SBA-15],并将其用于以质量分数30%的过氧化氢为氧化剂的苯酚羟化反应中.结果表明,Cu(Ⅱ)-Q-APS-SBA-15呈现出较高的苯酚转化率和苯二酚选择性.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 H202 （30%, mass fraction） as an oxidant. The reaction results indicate that Cu（ Ⅱ）-Q- APS-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.
