Synthesis,crystal structure and catalytic activity of a Waugh type polyoxometalate H12MnMo9O32(KO)6

摘要

A Waugh type polyoxometalate H12[MnMo9O32(KO)6]has been synthesized and characterized by single crystal X-ray diffraction,IR,XRD and TG.The compound was crystallized in the trigonal system,space group R3 with α=15.5380(6)nm,b=15.5380(6)nm,c=12.3777(5) nm,α=90°,β=90°,γ=120°, V=2587.98(18) nm3,Z=3,R1=0.0134,ωR2=0.0308.The catalytic activity of the title compound for the dehydration of cyclohexanol was determined.The conversion of C6H11OH reached 69.56% and the selectivity of C6H10 was 96% when the amount of catalyst,temperature range and reaction time were 6.59%,170℃-180℃,30 min,respectively.
