The definition of pore size according to the International Union of
Pure and Applied Chemistry (IUPAC) is that micropores are smaller than
2 nm in diameter, mesopores 2 to 50 nm and macropores larger than 50
nm. However this definition is somewhat in conflict with the definition of
nanoscale objects. Nanoporous materials are a subset of porous materials,
typically having large porosities (greater than 0.4), and pore diameters
between 1- 100 nm. In the field of chemical functional porous materials, it
is better to use the term "nanoporous" consistently to refer to this class of
porous materials having diameters between 1 and 100 nm. For most
functional applications, pore sizes normally do not exceed 100 nm
anyway. It is noted that nanoporous materials actually encompass some
microporous materials to all mesoporous materials.

应该不是这样的。
nanoporous的概念比较宽泛,但是要大于1nm或者叫10埃;
microporous是微孔的意思,您搞错了,应该是小于10埃的孔,而不是nm级;
macroporous是大孔的意思,您说得对;
...

谢谢指正,是偶记错了,汗
如浪子般风流似侠客般潇洒像英雄般悲壮
