“…As a typical catalyst for the CVD graphene growth, nickel (Ni) was naturally adopted for the growth of GNRs and GRNs with a width of 23 nm were easily obtained. [ 115 ] Initially, Ni nanorods were prepared via EBL and transferred to a Si/SiO 2 substrate. Then, a rapid‐heating CVD procedure was implemented using a mixture of hydrogen and methane gases to grow graphene on the Ni nanorods.…”

The realization that nanostructured graphene featuring nanoscale width can confine electrons to open its bandgap has aroused scientists’ attention to the regulation of graphene structures, where the concept of graphene patterns emerged. Exploring various effective methods for creating graphene patterns has led to the birth of a new field termed graphene patterning, which has evolved into the most vigorous and intriguing branch of graphene research during the past decade. The efforts in this field have resulted in the development of numerous strategies to structure graphene, affording a variety of graphene patterns with tailored shapes and sizes. The established patterning approaches combined with graphene chemistry yields a novel chemical patterning route via molecular engineering, which opens up a new era in graphene research. In this review, the currently developed graphene patterning strategies is systematically outlined, with emphasis on the chemical patterning. In addition to introducing the basic concepts and the important progress of traditional methods, which are generally categorized into top‐down, bottom‐up technologies, an exhaustive review of established protocols for emerging chemical patterning is presented. At the end, an outlook for future development and challenges is proposed.

“…Recently, employing electro-deposition to first form nickelcarbon nanowires, followed by a rapid thermal annealing and subsequent removal of the nickel core with nitric acid, GNRs with diameters of 32 nm have been prepared. [97] Having demonstrated the feasibility to catalyze the patterned growth of respective graphene films on nickel, Ge substrates have also been used recently. [98] By controlling the CVD condition in order to maximize the anisotropy growth, GNRs with sub 10 nm width were grown on the Ge (001) facets which govern their orientation.…”

As an emerging field of research, graphene patterning has received considerable attention because of its ability to tailor the structure of graphene and the respective properties, aiming at practical applications such as electronic devices, catalysts, and sensors. Recent efforts in this field have led to the development of a variety of different approaches to pattern graphene sheets, providing a multitude of graphene patterns with different shapes and sizes. These established patterning techniques in combination with graphene chemistry have paved the road towards highly attractive chemical patterning approaches, establishing a very promising and vigorously developing research topic. In this review, an overview of commonly used strategies is presented that are categorized into top‐down and bottom‐up routes for graphene patterning, focusing mainly on new advances. Other than the introduction of basic concepts of each method, the advantages/disadvantages are compared as well. In addition, for the first time, an overview of chemical patterning techniques is outlined. At the end, the challenges and future perspectives in the field are envisioned.
