In the expressions certains d’entre eux, aucun d’entre eux, etc., is there an explanation why there is a « de »? The meaning seems to be just « some of them » and « none of them », so I’m not sure why it is necessary to place a « de » in front of the preposition.

As underlined @oldergod, without « de » those expressions would not have the same meaning :
- certains / aucun = some / none
- de = of
- entre = between
- eux = them
So without « de » you have no link between the quantity (some/none) and the fact that this quantity is taken inside the group (of them).
You would be understood because it is not a big word missing, but it will appear as strange and incorrect – you will probably be corrected.
