Iridium- and osmium-decorated reduced graphenes as promising catalysts for hydrogen evolution
Renewable energy sources are highly sought after as a result of numerous worldwide problems concerning the environment and the shortage of energy. Currently, the focus in the field is on the development of catalysts that ...
Highly hydrogenated graphene through microwave exfoliation of graphite oxide in hydrogen plasma : towards electrochemical applications
Hydrogenated graphenes exhibit a variety of properties with potential applications in devices, ranging from a tunable band gap to fluorescence, ferromagnetism, and the storage of hydrogen. We utilize a one-step ...
Unusual inherent electrochemistry of graphene oxides prepared using permanganate oxidants
Graphene and graphene oxides are materials of significant interest in electrochemical devices such as supercapacitors, batteries, fuel cells, and sensors. Graphene oxides and reduced graphenes are typically prepared by ...
Iridium-catalyst-based autonomous bubble-propelled graphene micromotors with ultralow catalyst loading
A novel concept of an iridium-based bubble-propelled Janus-particle-type graphene micromotor with very high surface area and with very low catalyst loading is described. The low loading of Ir catalyst (0.54 at %) allows ...
