摘要:

光催化具有无污染、安全高效等优点,已成为环保领域的研究热点。 本文选择2,4-二(3,5-二甲基吡唑)-6-二乙基胺-1,3,5-三嗪(L1)和2, 6-二[3-(5-甲基吡唑基)]吡啶(L2)为配体、以RuCl3为金属源,合成了3种配合物[Ru(L1)Cl3](1)、[Ru(L2)2]·Cl3(2)和[Ru(L2)2]·(H2BTC)·(HBTC)·H2O(3),同时进行了IR、UV-Vis、TG及X射线衍射等表征,并对配合物在光催化降解罗丹明B方面进行了探讨,结果表明,配合物13均具有一定程度的光降解效果,降解效果分别为46.8%、44.7%和40.4%。 相同条件下,加入H2O2后的配合物13的降解效果比金属盐、配体及H2O2单独存在时的降解效果好。

Abstract:

As the photocatalytic reaction has the advantages of non-pollution, safe and efficient, so it has become a research hotspot of environmental protecting field. Therefore, this work choose 2,4-two (3,5-two methyl pyrazole)-6-two ethyl amine-1,3,5-three triazine(L1) and 2,6-di[3-(5-methylpyrazolyl)] pyridine(L2) as the ligands, RuCl3 as the metal source to synthesize three kinds of complexes, [Ru(L1)Cl3](1), [Ru(L2)2]·Cl3(2), and [Ru(L2)2]·(H2BTC)·(HBTC)·H2O(3). At the same time, the complexes were characterized by infrared(IR) spectrometry, ultraviolet-visible(UV-Vis), themogravimetry(TG) and X-ray diffraction, and the photocatalytic degradation of RhB was explored. The results show that the complexes 13 have a certain degree of photodegradation effect, the degradation efficiency is 46.8%, 44.7% and 40.4%, respectively. Under the same conditions, the degradation effects of the complexes are better than those corresponding only with metal salts, ligands and H2O2, respectively.
