Abstract: A process for oxidizing an alkyl substrate may comprise combining an alkyl substrate (e.g., propane, n-butane) and ozone in a liquid phase medium comprising a branched alkane activator (e.g., isobutane) and a protic additive (e.g., water) under conditions sufficient to oxidize the alkyl substrate to products. The alkyl substrate may be selected from linear and cyclic alkanes.

Abstract: Bimetal-incorporated mesoporous silicate catalysts are provided. In embodiments, such a catalyst comprises a silicate lattice, a first transition metal M, and a second transition metal M′, wherein M and M′ are selected from Zr, Nb, and W and are directly incorporated into the silicate lattice such that M and M′ replace Si atoms. Methods of using the catalysts are also provided, including in methods for dehydrating alcohols. Methods of making the catalysts are also provided.

Abstract: Processes for oxidizing alkanes are provided. In embodiments, such a process comprises combining an alkane, e.g., isobutane, and ozone in a liquid phase medium comprising a protic additive, e.g., water, under conditions sufficient to oxidize the alkane to products comprising a hydroxylate.
