摘要酞菁类化合物是一种具有高度共轭 18π 电子体系的功能性材料。由于大环共轭体 系间电子有强烈的相互作用，电子在可见光范围内可以产生较强的跃迁，使得该类化 合物在光、电、热等方面表现出独特的性能。 83372

近年来，研究人员对利用金属酞菁化合物对于某些难于处理的污染物进行光催化 处理的研究越发重视。由于这些反应只需要适量的光、氧气便能够在常温下进行，使 得这种技术在环境保护特别是水污染处理方面有着广阔的应用前景。虽然金属酞菁具 有良好的光催化活性，但在实际应用中存在容易氧化聚集造成催化性能降低和难以回 收的弊端，所以,将金属酞菁化合物进行负载便成为一种行之有效的方法。 

本课题通过以均苯四甲酸酐，二水合二氯化铜和尿素为反应物，钼酸铵为催化剂， 利用固相聚合合成八羧基酞菁铜。然后通过八羧基酞菁铜上的羧基与氧化石墨烯上的 羟基的脱水缩合反应进行负载，并对负载后的氧化石墨烯进行热还原。对上述产物进 行红外和紫外表征，确定接枝成键。最后通过对比试验验证出酞菁铜/石墨烯复合材 料确实在光催化性能上有所提升。

Abstract Phthalocyanine is a functional material which has a high conjugate structure of 18 π electronic system。 Due to the strong electronic interaction in the large ring conjugated system, electrons can produce a strong transition in visible range, so these compounds

show unique properties in terms of light, heat，electricity and so on。

In recent years, researchers pay more and more attention to the photocatalytic treatment of some pollutants which are difficult to be handled in using metal phthalocyanine compounds。 Because these reactions only need moderate light, oxygen will be able to carry out at room temperature, making this technology has broad application prospects in environmental protection especially in terms of water pollution treatment。 Although the metal phthalocyanine has good photocatalytic activity, but catalytic performance is usually been lowered due to the oxidized gathered and it has difficult in gathering in practical application。 Therefore, the metal phthalocyanine compound loading has become a kind of effective method。

In this report, copper octacarboxyphthalocyanine(CuPc[COOH]8) is synthesized through solid phase synthesis, where using pyromellitic anhydride, copper(II)chloride dehydrate(CuCl2·2H2O) and urea as reactants, molybdate as catalyst。 Then making copper octacarboxyphthalocyanine load onto graphene oxide by the dehydration condensation reaction of hydroxyl and carboxyl groups。 Following the previous step, the graphene oxide will be reduced through thermal treatment reduction。 The products will be characterized by SEM, IR and UV, determining whether the graft is successful or not。 Finally, compared with the experimental results, the copper phthalocyanine/graphene composites did improve the photocatalytic performance。

Keywords: metal phthalocyanine compound; graphene; loading; photocatalytic reaction
