The tetrairon(III)-substituted polytungstates [Fe-4(H2O)(10)(beta-XW9O33)(2)](n-) (n = 6, X = As-III, Sb-III; n = 4, X = Se-IV, Te-IV) were immobilized on (3-aminopropyl)triethoxysilane-modified SBA-15 and showed an excellent catalytic performance for solvent-free aerobic oxidation of long-chain n-alkanes using air as the oxidant under ambient conditions through a classical free-radical chain autoxidation mechanism.
