摘要
以钛酸丁酯,乙酰丙酮,三氯化铁,石墨粉为原料,制备了乙酰丙酮铁改性二氧化钛/石墨烯复合材料,通过红外光谱(IR)、比表面分析仪(BET)手段对复合材料进行表征,并以罗丹明B为降解物,在可见光照射下测试了材料的光催化性能,结果表明,乙酰丙酮铁作为铁源的添加可以提高二氧化钛的吸光性能,石墨烯的掺杂较大幅度提升二氧化钛的吸附能力以及电子导出能力,降低电子一空穴对的再结合速率,二者的协同作用提高了二氧化钛的光催化降解性能。
Fe -doped TiO2/GO photocatalysts were synthesized with tetrabutyl titanate, acetylacetone, ferric chloride and graphite powder. The photocatalystic performance of the prepared material was investigated by UV - visible spectroscopy, Infrared ray, BET, and photocatalytic degradation testing with Rodanmin B aqueous solution under visible light irradiation. The results indicated that ferric acetylacetonate improved the absorption of TiO2 and the graphene accelerate the electron conduction. The synergistic effect of the two improved the photocatalytic performance of TiO2.
