Selective ammoxidation of isobutane on a crystalline SbRe2O6 catalyst
Abstract
The catalytic ammoxidation of isobutane to methacrylonitrile at 673 K proceeds on a new class of Re mixed-oxide SbRe2O6 with alternate (Re2O6)3− and (SbO)+ layers, where ammonia is prerequisite for the C–H bond scission of isobutane.
