A spinel-type oxides ZnFe2O4 photocatalysts were prepared by citric acid complex method,and characterized with XRD,TG-DTA,FT-IR,TEM techniques.The photocatalytic activities were investigated by the degradation of C3H22N6O6S2Na2 by artificial visible Light.The results show that the photocatalytic activity of ZnFe2O4 is stable,under experimental conditions,the degradation rate of C3H22N6O6S2 is over 90% in 60min.
The title coordination polymer,[Zn(Pyphen)(PZDC)(H2O)](1) (Pyphen=pyrazino[2,3-f][1,10]phen-anthroline and H2PZDC=pyrazine-2,3-dicarboxylic acid) has been obtained by using hydrothermal synthesis and characterized by elemental analysis,IR,TG,fluorescence spectrum and X-ray diffraction single-crystal structure analysis.The crystal is of triclinic,space group P1 with a=0.681 8(14) nm,b=0.743 9(15) nm,c=1.759 8(35) nm,α=94.329(30) °,β=95.514(30) °,γ=97.043(3) °,V=0.878 2(3) nm3,Z=2,Mr=481.73,Dc=1.822 g·cm-3,μ=1.452 mm-1,F(000) =448,Rint=0.033 9,R=0.042 5,wR=0.090 7.In complex 1,PZDC ligands link the Zn(Ⅱ) ions to form 1D chain structures,and further extended into a 3D supramolecular framework through π-π interactions and hydrogen bonding interactions.In addition,complex 1 exhibits strong photoluminescence at room temperature.CCDC:649569.
