报道了一种合成碱土金属或过渡金属氧化物负载型介孔功能材料的直接法原位改性新途径.它不再沿袭传统的先合成样品再进行改性处理工艺思路,而是利用某些盐类不干扰强酸性合成体系,却易形成氧化物的特点,将它们加入合成体系,吸附/沉积于介孔硅分子筛表面上,但是在样品焙烧时转变成目标氧化物.新方法将合成和改性集为一举,在合成过程中同时就完成了调变改性.
Reported a new method of direct in situ modification of the synthesis of alkaline earth metal or transition metal oxide supported mesoporous functional materials.It no longer followed the traditional first synthetic samples and then modified treatment process ideas, Salt does not interfere with the strong acid synthesis system, but it is easy to form the characteristics of oxides, they are added to the synthesis system, adsorbed / deposited on the mesoporous silica molecular sieve surface, but the sample is transformed into the target oxide calcination .New method of synthesis and Modified set in one fell swoop, in the synthesis process at the same time to complete the modulation change.
