Synthesis of iron ‐based metal organic framework and its visible light‐driven photocatalytic degradation of dye pollutants

The simplified model of photocatalytic reaction mechanism. A new type of metal organic framework materials synthesized with good photocatalytic activity, which can degrade organic dye completely under visible light within 180  min. A novel metal –organic compound [Fe (ox)(phen)]n (phen  = 1,10‐Phennannthroline, ox = oxalate acid) has been hydrothermally synthesized and structurally characterized by X‐ray single‐crystal diffraction, X‐ray diffraction, IR, UV–vis diffuse reflectance spectroscopy and X‐ray photoelectron spectroscopy. The compound crystallized in monoc linic,space groupP21 with a  = 0.92289 (3) nm, b = 1.35719 (3) nm, c = 1.02012 (4) nm,β = 94.372 (2)°,V = 1.27402(8)nm3,Z  = 2,and exhibited a 2D layer structure. The photocatalytic activities of the compound were evaluated by decomposing Rhodamine B (RhB) and methyl orange (MO) under the visible light irradiation. In addition, the mechanism of the photocatalytic properties were proposed during this process.
