Abstract: A new charge-transfer compound (C2H8N)3(PW12O40)·2H2O  synthesised by hydrothermal technology using DMF-water as solvent which was characterized by IR spectroscopy,TG-DTA and single-crystal X-ray diffraction.The results show that the compound belongs to the trigonal system,R3m sapce group,and the cell parameters.Crystal data:trigonal,space group:R3m,a=1.626 82(12) nm,b=1.626 82(12) nm,c=2.481 9(4) nm,α=90°,β=90°,γ=120°,V=5.688 4(11) nm3Z=6,R1=0.057 7,wR2=0.144 4,S=1.006.The compound has good catalytic activity for the oxidative elimination of methanol.When the initial concentration of methanol is 5.37 g·m-3,and the flow rate is 4.51 mL·min-1,59% of methanol is eliminated at 175 ℃.

Key words: phosphotungstic acid, hydrothermal synthesis, catalytic, elimination, methanol
