Preparation and Structural Characterization of Platinum Nanosheets Intercalated between Graphite Powder with High Surface Area

• Platinum nanosheets having 1-4 nm thickness and 5-300 nm width were prepared between graphite layers. • Platinum nanosheets have a lot of hexagonal holes and edges with 120˚ angle. • Platinum nanosheets were selective catalysts for cinnamaldehyde hydrogenation in supercritical carbon dioxide. Synthesis of platinum nanoparticles intercalated between layers of commercially available graphite powder samples possessing surface area values ranging...
