Ball milling of graphite under a hydrogen atmosphere is an effective method of producing nanostructured graphite which is able to store an appreciable amount of hydrogen. Nanostructured graphite has potential for use as a low-cost in energy store, for vehicles and stationary hydrogen-energy applications.
Low-cost, high-yield production of graphene nanosheets (GNs) is essential for practical applications. We have achieved high yield of edge-selectively carboxylated graphite (ECG) by a simple ball milling of pristine graphite in the presence of dry ice. The resultant ECG is highly dispersable in various solvents to self-exfoliate into single- and few-layer (≤ 5 layers) …
