摘要: A Keggin-type polyoxomolybdate [H2biim]{Ni(biim)3(SiMo12O40)} [biim=1H,1'H-[2,2']biimidazolyl] has been synthesized under hydrothermal condition and characterized by XRD, temperature-dependent IR, TG, temperature-induced and magnetism-induced 2D infrared correlation spectroscopy (2D-IR COS) and UV-vis DRS in order to explore the relationship between structure and properties. Temperatureinduced 2D-IR COS spectroscopy indicates that the terminal Mo-Ou/v bonds are more sensitive than the bridging Mo=Ot bands to temperature variation, which is in agreement with the conclusion of temperature-dependent IR. Magnetism-dependent 2D-IR COS spectroscopy reveals the stretching vibration of the Mo=Ot occurs prior to the stretching vibration of the Mo-Ou/v, which is due to the coordination environment and the valence of the Siatom. The stability of compound 1 is investigated via TG and temperature-dependent IR. In RhB degradation, compound 1 shows good photocatalytic abilities.
