摘要
在不同的温度下制备VPO催化剂 ,采用BET、XRD和SEM等测试手段考察制备温度对催化剂的比表面及晶相结构的影响。实验结果表明 ,温度对比表面和晶相结构的影响存在一个最佳值。选择适宜的制备温度可以使催化剂晶粒变小 ,比表面增大 ,活性相含量增加。
VPO catalysts were prepared at different temperature. BET, XRD and SEM techniques were used to investigate the effect of preparation temperature on surface area and phase composition of the catalysts. The results showed that there is an optimum temperature for surface area and phase composition. Surface area and amount of active phase can be ienhanced at the optimum preparation temperature.
