摘要：

In this paper, the photocatalytic properties of NH2-MIL-125(Ti) is enhanced by using a simple nitric acid etching method to form a ligand defect strategy. The structures and properties of the samples are characterized by XRD, SEM, XPS, BET, TG, and UV-vis etc. The results display that the yield of modified NH2-MIL-125(Ti) photo -catalytic NO removal experiment is significantly improved based on excellent photoresponse capacity. The optimal sample (0.1 mol/L HNO3-NH2-MIL-125(Ti)) shows excellent photocatalytic activity for NO removal under visible light irradiation (42.69%), which was 1.84 times higher than that of the original NH2-MIL-125(Ti).
