Oxidative Dehydrogenation Properties of Novel Nanostructured Polyoxovanadate Based Materials

A comparative study of the catalytic oxidative dehydrogenation of propane by a novel polyoxovanadate based open-framework material (Co-POV)—[Co 3 V 18 O 42 (H 2 O) 12 (XO 4 )]·24H 2 O (X = V, S), which is composed of nanometer size vanadium oxide clusters interlinked by cobalt oxide {–O–Co–O–} motif...

Description
Summary:A comparative study of the catalytic oxidative dehydrogenation of propane by a novel polyoxovanadate based open-framework material (Co-POV)—[Co 3 V 18 O 42 (H 2 O) 12 (XO 4 )]·24H 2 O (X = V, S), which is composed of nanometer size vanadium oxide clusters interlinked by cobalt oxide {–O–Co–O–} motifs, showed that Co-POV has superior catalytic property as compared to its individual metal oxide constituents, vanadium oxide and cobalt oxide, and their mixture, with high propylene selectivity. Graphical Abstract Comparison of oxidative dehydrogenation (ODH) of propane catalytic properties of a nanostructured material—[Co 3 (H 2 O) 12 V 18 O 42 (XO 4 )]·24 H 2 O (Co-POV) with its building blocks—V 2 O 5 and CoO—shows Co-POV is a better ODH catalyst than its building blocks.
