【摘要】 首先运用改进Hummers法合成氧化石墨烯,利用氧化石墨烯表面的羧基与四氨基酞菁锌的氨基反应形成酰胺键从而将两者复合,合成掺杂比例为10%的氧化石墨烯/酞菁锌复合材料。通过红外光谱及X射线粉末衍射图谱对合成的氧化石墨烯及复合材料进行表征,并于可见光条件下对复合材料催化降解亚甲基蓝的性质进行研究。实验结果表明,在可见光条件下复合材料对亚甲基蓝溶液有一定的光催化降解活性,光照50分钟降解率可达75%。更多还原

【Abstract】 Graphene oxide was synthesized by improved Hummers method, and graphene/phthalocyanine zinc composite material of 10% ratios was formed through the amido bond between the amino group from ZnTAPc and the carboxyl group from surface of grapheme oxide. The composite materials were characterized by IR and XRD spectroscopy. And the photocatalytic degradation of methylene blue solution under visible light was researched by using phthalocyanine zinc and the composite materials as catalysts. The results show that the photocatalytic activity of the composite material was better than phthalocyanine, with the degradation rate of methylene blue over 75% in 50 minutes.更多还原
