英文摘要: Abstract(#br)Two-dimensional lamellar stacked (NH 4 ) 0.8 V 3 O 7 ·3.5H 2 O with controlled micromorphology was synthesized form hydrothermal method by adjusting the molar ratio of the NH 4 VO 3 with H 2 C 2 O 4 ·2H 2 O. The EDS, FT-IR, DSC&TG and XPS studies indicated that our product can be indexed as (NH 4 ) 0.8 V 3 O 7 ·3.5H 2 O. A minimum reflection loss (RL) value of −21.149 dB at 2.5 mm with effective absorption bandwidth (RL < −10 dB) of 3.611 GHz was realized on the lamellar stacked structure (NH 4 ) 0.8 V 3 O 7 ·3.5H 2 O sample, which was prepared with the NH 4 VO 3 and H 2 C 2 O 4 ·2H 2 O molar ratio of reactants is 1:1.25. The additional surface polarization and the surface resistance loss, which caused by the surface charge due to the specific surface of the lamellar stacked...
