“…47,48 The covalent functionalization is usually realized via substitution of carbon atoms in the basal plane of graphene by heteroatoms (atom doping), 49,50 reaction with residual functional groups on graphene, 51 or modication of graphene's unsaturated structure. [52][53][54][55][56][57] In contrast, the non-covalent chemical modication is oen realized by intermolecular interactions such as van der Waals forces, 58 electrostatic interactions, 59 or p-p stacking interaction. [60][61][62] In particular, the covalent functionalization of graphene sheets using organic functional groups has been explored as a pivotal step towards the formation of graphene composites at the nanoscale.…”

“…It is inevitable to solve these synthetic problems so that GNPs can be attached with novel functional molecules to obtain functionalized GNPs with hydroxyl, amino, and carboxylic terminal groups under milder and environmentally friendly conditions such as lower temperature, shorter reaction time, aerobic atmosphere, and aqueous media. With newly developed methods, novel functionalized GNPs derivatives with specific terminal groups can be prepared and be further employed in different applications such as supercapacitors [62][63][64], fuel cells [65], drug delivery [66], nanocomposites, controllable massive transport [67], and many other areas [68][69][70][71][72].…”

As the most studied two-dimensional material, graphene is still attracting a lot of attention from both academia and industry due to its fantastic properties such as lightness, excellent mechanical strength, and high conductivity of heat and electricity. As an important branch of graphene materials, graphene nanoplatelets show numerous applications such as in coating, fillers of polymer composites, energy conversion and storage devices, sensing, etc. Chemical functionalization can introduce different functional groups to graphene nanoplatelets and can potentially endow them with different properties and functions to meet the increasing demand in the fields mentioned above. In this minireview, we present an overview of the research progress of functionalized graphene nanoplatelets bearing hydroxyl, amino, and carboxylic terminal groups, including both covalent and noncovalent approaches. These terminal groups allow subsequent functionalization reactions to attach additional moieties. Relevant characterization techniques, different applications, challenges, and future directions of functionalized graphene nanoplatelets are also critically summarized.

“…Graphene can be functionalized by different treatments and sites with different functional groups to improve solubility and reactivity (such as reactions with MMC) and can lead to significant changes in related physicochemical properties. [ 61–67 ] For example, Zhong et al. [ 68 ] synthesized a pyridine‐ligand‐functionalized graphene that reacted with iron phthalocyanine (FePc) to form a hybrid material ( Figure 3 a).…”

Owing to their zero pollution and high efficiency, fuel cells and metal–air batteries show great potential for broad application to sustainable energy technologies. However, the use of expensive and scarce Pt‐based materials as cathode catalysts to overcome the slow kinetics of oxygen‐reduction reaction (ORR) limits the scalability of such devices. Recently, considerable progress has been made in the development of nonprecious‐metal ORR catalysts. Although metal macrocyclic complexes (MMC) exhibiting a well‐defined M‐N4 (M = Fe, Co, Mn, Cu, etc.) structure (which can provide open sites to combine with oxygen and catalyze ORR) have attracted widespread attention, the MMC ORR performance is usually unsatisfactory because MCCs exhibit poor conductivity, symmetric electron distribution, inferior O2 adsorption, and low activation. However, MMC‐modified conductive‐carbon materials effectively solve such problems and simultaneously boost the ORR catalytic activity. In this review, the recent achievements in MMC‐functionalized carbon materials as ORR catalysts are summarized, and the current challenges and prospects of MMC‐functionalized carbon‐based ORR catalysts are discussed based on recent experimental and theoretical studies.
