The dehydration of glycerol into acrolein was investigated over small‐sized γ‐Al 2 O 3 prepared by a metal–organic framework (MOF) templated method. The particle size of alumina strongly affected the final physicochemical properties of γ‐Al 2 O 3 as well as its catalytic activity. The MOF‐derived, small‐sized γ‐Al 2 O 3 (M‐Al 2 O 3 ) catalyst exhibited higher stability and higher activity in the glycerol dehydration reaction than conventional bulk γ‐Al 2 O 3 and nanorod γ‐Al 2 O 3 owing to enriched intercrystal mesopores and an abundance of accessible acid sites. M‐Al 2 O 3 retained its high glycerol conversion (over 80 %) for nearly 200 h, whereas high acrolein selectivity (74 %) was achieved.
