Temperature-controlled and aerosol-assisted synthesis of aluminium organophosphonate spherical particles with uniform mesopores.

Spray-drying of clear precursor solution containing inorganic-organic hybrid species and EO(n)PO(m)EO(n) triblock copolymer at low temperature, followed by treatment in acetone to remove the triblock copolymer, afforded spherical particles of aluminium organophosphonate (AOP) with uniform mesopores.
