Facet-dependent catalysis of γ-Bi2MoO6 for selective oxidation of isobutene to methacrolein

γ-Bi 2 MoO 6 nanosheets catalyzed the selective oxidation of isobutene to methacrolein with a conversion of 88% and a selectivity of 67% due to the preferential termination of the reactive molybdenum species on the {010} facets.
