Narrow pore size distribution may be beneficial to the selectivity of product in catalysis.
It at the same time can affect another catalyst parameters, such as diffusion limitation and particle size ...

分布窄只是为了体现可控这个概念而已，在催化效果上要视情况而定

分布窄说明材料的孔径比较单一，和催化剂活性没有直接的关系，如果有影响的话肯定是影响到了其他因素，比如说扩散传质等，如果是负载的催化剂，对负载金属的颗粒大小均匀程度等可能有影响，然后影响活性。我感觉主要 ...

会影响到相对表面积的吧？
做反应了么？催化效果上怎么样？
