Foreign Atoms Help Monolayer Graphene Overcome Limitations

Researchers at Daegu Gyeongbuk Institute of Science and Technology (DGIST) have introduced a simple methodology that enables the fine control over the integration of foreign atoms with graphene. From that control, the researchers developed composite graphene-based heterostructures that exhibited synergistic oxygen evolution reaction electrocatalytic performance, and that can be used to store energy at low cost, and fabricate ultrathin, wearable electronics. In the work, the researchers developed graphene monolayer/metal-oxide nanostructures (GML/MONSs) by using a low-temperature technique known as electrochemical deposition, in which they grew metal oxide nanostructures exclusively on the native defect sites of graphene.
