Oxidative coupling of bio-alcohols mixture over hierarchically porous perovskite catalysts for sustainable acrolein production.

The acrolein production from bio-alcohols methanol and ethanol mixtures using AMnO (since A = Ba and/or Sr) perovskite catalysts was studied. All the prepared samples were characterized by XRD, XPS, N sorption, FTIR, Raman spectroscopy, TEM, SEM, TGA, and NH-CO-TPD. The catalytic oxidation reaction to produce acrolein has occurred two steps, the alcohols are firstly oxidized to corresponding aldehydes, and then the aldol is coupled with the produced aldehydes.
