In this work, we developed a general two-step method to prepare molybdenum carbide (Mo2C) nanoparticles stabilized by a carbon layer on reduced graphene oxide (RGO) sheets. The Mo2C-RGO hybrid showed excellent performance, which is attributed to the intimate interactions between Mo2C and graphene as well as the outer protection of the carbon layer.
Dimensionssteigerung: Hohle Oktaeder aus Rutil‐ähnlichem SnO2 wurden in einer templatfreien Hydrothermalsynthese erhalten, indem das Zusammenlagern von Nanokristalliten zu zweidimensionalen Strukturen und die Stabilisierung einer Familie von {111}‐artigen Kristallflächen in 2‐Propanol/Wasser in Gegenwart von Ethylendiamin genutzt wurde. In TEM‐Bildern gibt sich der zentrale Hohlraum des Oktaeders als hellere Region zu erkennen (siehe Bild).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
