由于纳米颗粒具有大的比表面积和极高的化学反应活性,纳米化学越来越受到业内人士研究的范畴,在许多领域得到广泛的应用。它可与硝基、羟基、卤代烃等进行还原反应,还可以与茂钛化合物组成烯烃加氢的催化剂,促进化学反应。该文通过三个典型化学反应实例,比较用纳米NaH与用商品NaH分别作为化学试剂,反应他们之间活性的关系,证明纳米NaH的高化学反应活性的原因。
Due to the large specific surface area and high chemical reactivity of nanoparticles, nanocrystallines are becoming more and more popular in the industry and widely used in many fields. It can with nitro, hydroxyl, halogenated hydrocarbons, etc. for reduction reaction, but also with the titanocene olefin olefin hydrogenation catalyst composition to promote chemical reactions. In this paper, three typical chemical reaction examples were compared, and the relationship between the activity of the nano-NaH and the commercial NaH was compared respectively to prove the reason for the high chemical reactivity of the nano-NaH.
