| 摘要: | The nanometer titanium dioxide (TiO2), succinic acid (SUA), and the mixture of nano- TiO2 and SUA were dispersed or dissolved in pure water, then irradiated with UV at the wavelength of 254 nm under stirring for different time periods respectively. The pH and conductivity values and UV-vis spectra of those solutions were recorded immediately. The powders obtained from the filtrated and vacuum dried from those solutions were examined with Fourier Transform Infrared Spectroscopy and Wide Angle X-Ray Diffraction meter. It shows that the crystalline structure and IR and UV-vis spectra of SUA adsorbed on nano-TiO2 particles are changed. The photo-reduced succinic acid in the presence of nanometer titanium dioxide under UV irradiation can create aldehyde group on SUA and free radical of SUA to improve the catalytic effects of crosslinking reaction between SUA and cotton cellulose. |
