Claim 19:
20. A post-modification process for forming superficially porous particles with chromatographically enhanced properties from the plurality of superficially porous of claim 1, the post-modification comprising at least one of:
i. removing a template by at least one of calcination and extraction;
ii. increasing pore size and eliminating small mesopores (<5 nm) by at least one of a hydrothermal method and etching;
iii. increasing a mechanical strength of the superficially porous particles by sintering;
iv. activating a plurality of functional surface groups by at least one of the hydrothermal method and etching; and
v. functionalizing a plurality of surface groups of the plurality of superficially porous particles 100 with organic silanes to form a plurality of functionalized surface groups.
