Abstract
•Esterification of glycerol into acetins studied over two series of SiAl-based solids.•Acid SiAl with a defined hierarchy of pores was synthesized.•Molybdophosphoric heteropolyacid supported SiAl nanotubes.•A 50 wt% of molybdophosphoric on nanotubes lead to selectivity towards the acetins.•Acidity, stability structure and porosity of the MPA on nanotubes gave best results.
