活性品类
Examples
- The regulation of acid catalytic property of molecular sieve can be realized via surface modification of mesoporous molecular sieve by means of introducing doping metals into skeleton or loading active species onto matrix during synthesizing precursor for mesoporous molecular sieve
在合成介孔分子筛的前驱物中掺杂其他金属元素而将其引入骨架或将活性组分负载到介孔分子筛的基体上，可以实现对介孔分子筛表面进行表面修饰与改性，以调变分子筛表面的酸催化性能。
