| Abstract：A series of tungstic oxide powders were prepared by calcinating tungstic acid gels or sols obtained from exchanging of Na2WO4 with protonated cation exchange resin in the dynamic method. Effects of thermal treating tungstic acid methods on morphology,infrared spectra patterns and photocatalytic activity were studied. The products were characterized by TGA,FTIR and electron probe microanalysis(ETMA). The results showed that infrared spectra absorbance and photocatalytic activity were related to distinct powd... |
