Abstract

A silica–alumina (SiO2–Al2O3) surface possessing both In3+ cations and an amine base has been prepared. Surface-functionalized SiO2–Al2O3 was characterized by solid-state 29Si MAS, 13C CP/MAS, and 27Al 2D MQ/MAS NMR spectroscopy; X-ray photoelectron spectroscopy; and elemental analysis. The bifunctional surface demonstrates synergistic catalysis for cyanoethoxycarbonylation of aldehyde.
