Recently, the work titled “Visualization of electrocatalytic activity of three-dimensional MoSe2@reduced graphene oxide hybrid nanostructures for oxygen reduction reaction” done by Dr. Fei Li and her team has been accepted to be published on Nano Research (IF 8.893). The work reports the synthesis of three-dimensional rose bud-like MoSe2@rGO hybrid nanostructures with good electrocatalytic activity for oxygen reduction reaction (ORR). And the scanning electrochemical microscopy (SECM) technique was applied to investigate the local electrocatalytic activity of the MoSe2@rGO composite for ORR from a micrometer point of view.
