通过一种研究较少的原位热压合成方法，将磷钨酸H3PW12O40（记为PW12）在短时间内快速结合到金属-有机骨架mfp -300（In）中，得到新型PW12@MFM-300（In）复合材料。这种无溶剂的制备过程不仅环保，而且节省能源/时间。通过不同的物理和化学表征证实了pw12在MFM-300（In）中的包含。有趣的是，PW12@MFM-300（In）作为一种新型异催化剂，在可见光催化降解药物活性化合物磺胺乙嗪（SMT）中表现出协同活性。4-PW12@MFM-300（In）具有优异的鲁棒性，在室温下2 h内对SMT的去除率高达98%左右，并且可以多次回收用于该催化过程。
Through a less-investigatedin-situhot-pressing synthesis method, the phosphotungstic acid H3PW12O40(denoted as PW12) was rapidly incorporated into a metal-organic framework MFM-300(In) in a short time, affording novel PW12@MFM-300(In) composites. This solvent-free preparation process is not only environment-friendly but also energy/time-saving. The inclusion of PW12in MFM-300(In) was demonstrated by different physical and chemical characterizations. It was interesting to find that PW12@MFM-300(In) as new heterocatalysts display synergistic activity for the visible-light-driven catalytic degradation of pharmaceutically active compound sulfamethazine (SMT). 4-PW12@MFM-300(In) with excellent robustness possesses the high removal efficiency of about 98% toward SMT within 2 h at room temperature, and can also be recycled multiple times for this catalytic process.
