Boron-hyperdoped silicon for the selective oxidative dehydrogenation of propane to propylene

Boron containing catalysts have great potential in the oxidative dehydrogenation of propane. Herein, a series of 15, 25 and 42 at% boron-hyperdoped silicon catalysts synthesized by laser pyrolysis was studied. Boron-hyperdoped silicon samples showed >6 times higher propylene productivity than com...

Description
Summary:Boron containing catalysts have great potential in the oxidative dehydrogenation of propane. Herein, a series of 15, 25 and 42 at% boron-hyperdoped silicon catalysts synthesized by laser pyrolysis was studied. Boron-hyperdoped silicon samples showed >6 times higher propylene productivity than commercial h-BN at 450 °C. Boron-hyperdoped silicon with enriched surface BO x and B-OH species showed enhanced propylene productivity in the oxidative dehydrogenation of propane.
