BSTRACTHoley graphene (hG)

also called graphene nanomesh

is a structural derivative of graphene. hG is formed by removing a large number of atoms from the graphitic plane to produce holes distributed on and through the atomic thickness of the graphene sheets. These holes

sometimes with abundant functional groups around their edges

impart properties that are uncommon to intact graphene but advantageous toward various applications. In this review

strategies to prepare hG and the related applications that take advantage of the unique structural motif of these materials are discussed. Prospects are then given for this emerging class of graphene derivatives.
