Findings from Hunan University Provides New Data on Materials Science (Rational Construction of Strongly Coupled Metal-Metal Oxide-Graphene Nanostructure with Excellent Electrocatalytic Activity and Durability)

By a News Reporter-Staff News Editor at Journal of Technology -- Investigators publish new report on Materials Science. According to news reporting from Changsha, People's Republic of China, by VerticalNews journalists, research stated, "The interaction within heterogeneous nanostructures can provide a great opportunity to radically enhance their electrocatalytic properties and increase their activity and durability. Here a rational, simple, and integrated strategy is reported to construct uniform and strongly coupled metal metal oxide-graphene nanostructure as an electrocatalyst with high performance."

The news correspondents obtained a quote from the research from Hunan University, "We first simply synthesized the interacted SnO2-prGO (protected and reduced graphene oxide) hybrid with SnO2 nanoparticles (similar to 4 nm) selectively anchored on the oxygenated defects of rGO using an in situ redox and hydrolysis reaction. After the deposition of Pt, uniform Pt NPs are found to contact intimately and exclusively with the SnO2 phase in the SnO2-prGO hybrid. This constructed nanostructure (Pt-SnO2-prGO) exhibits significantly improved electrocatalytic activity (2.19-fold) and durability (2.08-fold) toward methanol oxidation over that of the state-of-the-art Pt/C catalyst."

According to the news reporters, the research concluded: "The detailed explanation of the strong coupling between SnO2 and graphene as well as between Pt and SnO2 is discussed, revealing that such a process can be used to immobilize various metal catalysts on metal-oxide-decorated catalysts for realizing advanced catalytic systems with enhanced performance."
