Superficially porous particles are provided. Aspects of the superficially porous particles include a non-porous inner core and a porous outer shell that includes inner and outer porous regions. The inner porous region can include ordered cylindrical pores substantially perpendicular to the non-porous inner core. The outer porous region can include conical pores which extend to the surface of the particles and which are in fluid communication with the cylindrical pores of the inner porous region. Also provided are methods of making the subject superficially porous particles. Aspects of the methods include subjecting substantially solid inorganic oxide particles to agitation in an aqueous solution in the presence of a first cationic surfactant and a second anionic surfactant, which together form micelles, to pseudomorphically transform the particles.
