| 英文摘要 | Controlling the phase transformation and grain growth of ZrO2 crystals at higher firing temperatures remains to be a key challenge for the scalable manufacturing of zirconia nanofiltration membranes. This work presents a ZrO2 nanofiltrationmembrane prepared by a sol-gel process combined with an in-suit polymerization method. The effects of the addition of acrylamide monomer and following with polymerization on the structure, phase transformation, and crystal growth of the ZrO2 powders were investigated and characterized using differential scanning calorimetric analysis (TG-DTA), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Field emission scanning electron microscopy (FESEM), High-resolution transmission electron microscopy (HRTEM) and Nitrogen adsorption-desorption. It was found that the optimized synthesis condition for preparing a stable zirconyl oxalate (ZrOC2O4) sol in which the precursor solution concentration was 0.05 mol L-1, a molar ratio of [H2C2O4]:[ZrOCl2] was 0.6:1, at a reaction temperature of 50 degrees C. The formation of polymer networks through adding acrylamide and polymerizing the sol contributes to the stabilization of the tetragonal phase and inhibits the phase transformation from t-ZrO2 to m-ZrO2. Further research showed that the growth of zirconia grains was also effectively controlled. Consequently, a continuous crack-free membrane synthesized from Zr-2 sol at a firing temperature of 500 degrees C was obtained. The water flux of the membrane was approximately 23 L m(-2) h(-1) bar(-1); the retention rate of NaCl solutions (1000 ppm to 5000 ppm) were less than 5%; and the nanofiltration performance showed a molecular weight cut-off (MWCO) of 760 Da, corresponding to a pore size of 1.38 nm. |
