一般沸石分子筛催化剂都为白色啊！！
The heats of CH3OH and NH3adsorption on zeolite-like aluminophosphates AlPO4-5, AlPO4-17, and AlPO4-18 were measured calorimetrically. The isotherms of adsorption of CH3OH and H2O at different temperatures were determined for the same materials. The energetics of adsorption of polar molecules show...
Lewis酸是脱HF反应活性中心,通过对比反应前后AlPO4催化剂的吡啶红外和NH3-TPD结果可知,反应后的AlPO4含有更高含量的Lewis酸,并以弱酸为主。此外,相比新鲜的AlPO4催化剂,反应后的催化剂检测到了强电负性的F元素,结合已报道的工作可以合理...
