TEM images showed that microwave prepared Ptnanoparticles supported on GNFs were small and uniform, and the average diameter was about 3.4nm. Cyclic voltammetric test showed that Pt/GNFs exhibited very high electrocatalytic activity formethanol oxidation.展开更多

MoS2-coated MWCNs would be expected to have different tribological and mechanical properties compared to MoS2, so it may have potential applications in many fields.展开更多
