The discovery of graphene and subsequent verification of its unique properties have aroused great research interest to exploit diversified graphene‐analogous 2D nanomaterials with fascinating physicochemical properties. Through either physical or chemical doping, linkage, adsorption, and hybridization with other functional species into or onto them, more novel/improved properties are readily created to extend/expand their functionalities and further achieve great performance. Here, various functionalized hybridizations by using different types of 2D nanomaterials are overviewed systematically with emphasis on their interaction formats (e.g., in‐plane or inter plane), synergistic properties, and enhanced applications. As the most intensely investigated 2D materials in the post‐graphene era, transition metal dichalcogenide nanosheets are comprehensively investigated through their element doping, physical/chemical functionalization, and nanohybridization. Meanwhile, representative hybrids with more types of nanosheets are also presented to understand their unique surface structures and address the special requirements for better applications. More excitingly, the van der Waals heterostructures of diverse 2D materials are specifically summarized to add more functionality or flexibility into 2D material systems. Finally, the current research status and faced challenges are discussed properly and several perspectives are elaborately given to accelerate the rational fabrication of varied and talented 2D hybrids.

“…phase technique. [69] TEM characterization results confirmed that the NiÀAl LDH nanosheets wereu niformly attached onto the surface of rGO, which could effectively decrease the agglomeration of NiÀAl LDH (Figure 9). Yang and Li synthesized NiÀCo LDH nanosheets with an etwork structure by growing them on rGO-Ni foam by means of electrodeposition, [70] which could reduce the cumbersome number of steps required to make the device and removed the need for additional additives.…”
