Catalyzed oxidation of mercaptoethanol by mesoporous molecular sieves supported phthalocyanine copper
α-Octo-isopentyloxy phthalocyanine copper is supported on SBA-15 and MCM-41 mesoporous molecular sieves by impregnation to produce CuPc/SBA-15 and CuPc/MCM-41 catalysts which are used in oxidation of mercaptoethanol.They are characterized by using UV-vis absorption spectra,IR spectra and N,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℃.
