摘　　要：采用浸渍法将α-八-(异戊氧基)酞菁铜分别负载在SBA-15和MCM-41介孔分子筛上,制备了CuPc/SBA-15和CuPc/MCM-412种复合催化剂。通过紫外-可见吸收光谱、红外光谱和N2吸附方法对催化剂的结构和组成进行了表征。测试了2种催化剂对巯基乙醇的催化氧化性能,并考察了温度对催化氧化活性的影响。实验结果表明,在pH=11时,CuPc/SBA-15催化氧化巯基乙醇的转化率高于CuPc/MCM-41;随着温度的升高,CuPc/SBA-15对巯基乙醇的转化率逐渐增大,并计算了CuPc/SBA-15催化反应在25℃时的活化能Ea为30.50kJ/mol。α-Octo-isopentyloxy phthalocyanine copper is supported on SBA-15 and MCM-41 mesoporous molecular sieves by impreg- nation to produce CuPc/SBA-15 and CuPc/MCM-41 catalysts which are used in oxidation of mercaptoethanol. They are characterized by u- sing UV-vis absorption spectra, IR spectra and N2 absorption. The catalytic oxidation activity of these two catalysts is measured, and the effects of temperature is investigated. The experimental results indicate that the conversion rate of CuPc/SBA-15 to mercaptoethanol is greater than that of CuPc/MCM-41 to mercaptoethanol at pH = 11. The conversion rate of CuPc/SBA-15 to mercaptoethanol improves with the rising of temperature, and the activation energy of the CuPc/SBA-15 is calculated to 30. 50 kJ/mol at 25℃.
