Emerging two‐dimensional (2D) materials have stimulated tremendous scientific and industrial interests due to their diverse and tunable physical, chemical, and mechanical properties. The scalable production of high‐quality wafer‐scale 2D materials has become significantly essential to bring us closer to practical industrial applications, particularly in electronic devices. Vapor‐phase growth provides attractive opportunities for the synthesis of large‐area and high‐quality 2D materials. In this review, we will emphasize vapor‐phase growth strategies from three aspects, including suppressing nucleation, seamless stitching, and evolutionary selection growth. We discuss the general understanding of the related fundamental mechanism and specific parameter optimization from precursors and substrate design to the adjusting of growth parameters (temperature and pressure). Meanwhile, we present other strategies to produce various kinds of wafer‐scale 2D materials. Finally, we conclude the current challenges and future directions in this developing field. This work may inspire researchers to better design routes in the synthesis of wafer‐scale 2D materials with high quality.

Among the significant growths of liquid metal (LM) research achieved over the past few years, the field of LM as catalysts offers promising opportunities for material scientists to exploit, and thus, burgeoning progress has been made. This article presents an overview of recent progress in developing LM catalysis, which spans from liquid-phase catalysts, photocatalysts, heterogeneous catalysts, and bimetallic catalysts, to catalysts based on liquid-metal/metal-oxide (LM/MO) frameworks. The different types, preparation methods, and typical applications of LM catalysts are classified and reviewed. Typical catalytic applications of LM systems discussed include the growth of graphene films/nanoribbons/carbon nanotube, photocatalytic degradation of CR or PFOA/splitting of H O/reduction of CO , and catalytic reactions like butane or acetylene dehydrogenation, methanol steam reforming, and reduction of potassium ferricyanide. The prospects, future trends, and challenges of LM catalysts are also mentioned.

“…Rational designing of a binary catalyst can be significant to control nucleation density, number of layers, solubility of carbon and dopant, which will provide significant control in the CVD growth process. Bilayer graphene with AA, AB stacking and rotation stacking fault is interesting prospect to observe novel physical properties (Figure 7(a)) [75][76][77]. It has been demonstrated that applying a vertical electric field in bilayer graphene-based field effect transistor (FET), a bandgap of the order of 0.2-0.3 eV can be observed [78].…”

Graphene, the atomically thin sheet of sp 2 hybridized carbon atoms arranged in honeycomb structure, is becoming the forefront of material research. The chemical vapor deposition (CVD) process has been explored significantly to synthesis large size single crystals and uniform films of monolayer and bilayer graphene. In this prospect, the nucleation and growth mechanism of graphene on a catalytic substrate play the fundamental role on the control growth of layers and large domain. The transition metals and their alloys have been recognized as the active catalyst for growth of monolayer and bilayer graphene, where the surface composition of such catalysts also plays critical role on graphene growth. CVD-synthesized graphene has been integrated with bulk semiconductors such as Si and GaN for the fabrication of solar cells, photodetectors, and lightemitting diodes. Furthermore, CVD graphene has been integrated with hexagonal boron nitride (hBN) and transition metal dichalcogenides (TMDCs) for the fabrication of van der Waals heterostructure for nanoelectronic, optoelectronic, energy devices, and other emerging technologies. The fundamental of the graphene growth process by a CVD technique and various emerging applications in heterostructure devices is discussed in detail.
