摘要：

以无水三氯化铋(BiCl3)和三氯化钒(VCl3)为原料，乙醇为氧供体，通过非水解溶胶–凝胶法(NHSG)制备了钒酸铋(BiVO4)黄色色料。分别通过X射线衍射和场发射扫描电子显微镜分析了色料的晶体结构和显微形貌，采用Fourier变换红外光谱(FTIR)探究了非水解溶胶–凝胶法制备BiVO4黄色色料的反应过程。同时系统研究了Bi/V摩尔比和温度对色料色度值的影响。结果表明：该色料为单斜白钨矿型(m-BiVO4)，粒径尺寸约为400 nm。同时，采用非水解溶胶–凝胶法能够实现BiVO4色料的低温合成，合成温度由传统固相法的650 ℃降至400 ℃，且色料呈亮黄色，当Bi/V摩尔比为1.1时，制备出的色料色度值为L*=61.6、a*=2.74、b*=62.9，远高于采用固相法合成BiVO4色料的色度值。FTIR测试表明，非水解溶胶–凝胶法制备BiVO4黄色色料的反应过程为钒醇盐和金属卤化物间发生非水解亲核取代反应，缩聚形成BiVO4，有利于提高样品的均匀性和降低合成温度。

BiVO4 yellow pigment was prepared by a non-hydrolytic sol–gel (NHSG) method, using bismuth trichloride (BiCl3) and vanadium trichloride (VCl3) as raw materials, ethanol as oxygen donor, respectively. The phase composition and the morphology of the pigment were studied by means of X-ray diffraction patterns and field emission scanning electron microscope, and the NHSG process of BiVO4 yellow pigment was investigated by Fourier transform infrared (FTIR) spectroscopy. The effects of Bi/V molar ratio and temperature on the chromatic value of the pigment were systematically studied. The results indicate that the resulting products have monoclinic scheelite-structure, and the particle size is about 400 nm. Meanwhile, the BiVO4 pigment can be synthesized via NHSG method at low-temperature. Compared with the conventional solid state method, its synthesis temperature is decreased from 650 ℃ to 400 ℃, and the pigment exhibits brighter yellow hue. When the molar ratio of Bi/V is 1.1, the BiVO4 yellow pigment shows excellent chromatic performance, as L*=61.6，a*=2.74，b*=62.9, which is much higher than that of the sample prepared by the conventional solid state method. FTIR spectra results show that the vanadium alkoxide react with metal halide through non-hydrolytic nucleophilic substitution reaction, and BiVO4 gel is formed via polycondensation process, resulting in the highly homogeneous samples and the low synthesis temperature.
