Description

technical field

[0001] The invention is a method for measuring the size distribution of nanoscale particles, specifically, a method for separating particles with different particle sizes by capillary electrophoresis and then measuring the particle size distribution. Background technique

[0002] Due to its small particle size, large specific surface area and quantum size effect, nano-powder materials have special properties that conventional coarse-grained materials do not have, and exhibit outstanding performance in light absorption, light filtering, catalysis and other functional properties. Eye-catching application prospects. The particle size and distribution have a great relationship with the overall performance of the material. Taking nanocatalyst as an example, the particle size and particle size distribution of nanocatalyst directly affect its catalytic performance. If the particle size distribution is very wide, or even only a small part of the particle size is at ...
