| Abstract: The TiSAPO-34 molecular sieves have been successfully synthesized via a facile hydrothermal method. Scanning electron microscopy (SEM), powder X-ray diffraction (XRD), Fourier transform infrared (FT-IR), N2 adsorption-desorption, UV-Vis diffuse reflectance spectra (UV-Vis DRS) and thermogravimetric (TG) have been employed to determine the properties of the samples. The TiSAPO-34 molecular sieves could be served as efficient adsorbents for adsorbing a typical contaminants, methylene blue (MB) from water. Moreover, the doped amount of titanium, the stability and recyclability of the catalysts have been investigated in detail. The results revealed that the resulting samples were the spherical microporous molecular sieve, which with good thermal stability. Interestingly, a certain amount of Ti atoms could embed the matrix of SAPO-34 molecular sieves successfully, and the skeleton structure of SAPO-34 molecular sieves still maintained. Importantly, the samples synthetic after crystallization at 190℃ for 24 h exhibited the optimal adsorption performance for the adsorption of MB, giving an adsorption rate of 80% after 1 hour. |
