Abstract A silica–alumina (SiO 2 –Al 2 O 3 ) surface possessing both In 3+ cations and an amine base has been prepared. Surface‐functionalized SiO 2 –Al 2 O 3 was characterized by solid‐state 29 Si MAS, 13 C CP/MAS, and 27 Al 2D MQ/MAS NMR spectroscopy; X‐ray photoelectron spectroscopy; and elemental analysis. The bifunctional surface demonstrates synergistic catalysis for cyanoethoxycarbonylation of aldehyde.
