Synthesis and photocatalytic performance of UiO-66 derivatives supported heteropolyacids
Metal-organic framework UiO-66-derived HPW@C-ZrO2 composites were synthesized by a hydrot-hermal method followed by a pyrolysis treatment using zirconium(IV)chloride and tungstophosphoric acid as raw materials,and terephthalic acid as ligand.The physical and chemical properties of the as-prepared composite materials were characterized by FTIR,XRD,N2 physisorption,SEM,and UV-Vis DRS,and Rhodamine B was used as the target pollutant to test their photocatalytic activity.The results showed that the introduction of HPW can improved the photocatalytic performance of original materials effectively.After a visible light irradiation for 120min,the degradation rate of HPW@C-ZrO2 to Rhodamine B reached 86.7%.Meanwhile,the cyclic experiments indicated that the composite photocatalytic material had good stability.
