Tuning the pore size from micro- to meso-porous in thermally stable aluminophosphates

Abstract

Thermally stable porous aluminophosphates (ICMUV-3) with P/Al molar ratios in the range 0.15 ≤ P/Al ≤ 0.75 and showing continuously adjustable pore sizes from 13 to 37 Å have been prepared through a surfactant-assisted procedure without changing the surfactant length and/or addition of organic expansors.
