TEM XRD 不一致，H2-TPR表述 求解答
|
|
问题1 XRD中没有明显特征峰，为宽泛弥散峰，但TEM中颗粒分布为1-15nm，有聚集，想解释为TEM看的是颗粒，颗粒有许多晶粒组成，但找不到文献支持，麻烦哪位能提供相关英文文献。 问题2，XRD中如此表述是否恰当，it should be noted that the characteristic peaks of catalyst became wider and weaker because the grain size of the catalyst is very small, short-range order and long-range disorder, indicating that --- species disperse in monolayers or amorphous phase on the surface of carrier. 如果可以是否有文献支持。 问题3，H2-TPR 中有一个大峰，是否可以说 It is also found that only one reduction peak appeared in the H2-TPR spectrum indicating the similar adsorption and diffusion of hydrogen and the process of reduction simultaneously , which improve the uniformity of the particle size. 如果可以有没有文献支持 |
