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.
