“…Nanodiamonds and graphitized‐NDs have been used as supports for several metal nanoparticles: ND−Pt NPs and G‐NDs−Pt NPs hybrids were used for the dehydrogenation of cyclohexane or propane and butane, respectively. In the first case, the catalytic activity was higher than that of a Pt/C catalyst, which was attributed to the stable Pt NP support by the three‐dimensional packing of ND and efficient mass transfer via the interconnected through‐hole pores in the porous diamond spherical particles .…”

Nanocarbons represent useful scaffolds in the preparation of last generation nanostructured catalysts, and their chemical functionalization through covalent or non‐covalent modification is becoming an important tool for introducing well‐distributed anchoring points and, in the meantime, could be the first step toward the assembling of hybrid nanostructured materials with a hierarchical order. In this Review are reported synthesis and catalytic applications of chemically modified nanocarbons such as fullerene, carbon nanotubes, graphene, nanohorns and nanodiamonds in organocatalytic and metal‐based (metal nanoparticles, organometallic complexes) reactions, covering major chemical reactions encompassing, the oxidation of alcohols, aldehydes, olefins, and silanes, hydrogenation reactions of aldehydes, ketones, and alkenes, dehydrogenative coupling of silanes, C−C coupling reactions, epoxidation of alkenes, CO2 fixation into cyclic carbonates, and asymmetric reactions, among others.

“…Minor variations in preparation conditions can significantly influence the delicate balance of conflicting demands: high activity, high selectivity, and longterm stability. Several classic synthesis methods have been developed for preparing graphitized nanocarbon-supported catalysts, including impregnation [58][59][60][61][62], chemical vapor deposition [63][64][65], precipitation and coprecipitation [47,48,66], and liquid-phase reduction [67,68]. Owing to the high surface area and excellent physical and chemical properties of graphitized nanocarbon, highly and uniformly dispersed active metals can be achieved by traditional loading methods.…”

“…The key challenges involve preventing the stacking of graphene sheets and achieving complete dispersion of individual single-layer graphene in various solvents to support active phase. Unlike the simple agglomeration feature of 2D-structure graphene, some other 0D and/or 3D sp 2 carbon materials, such as onionlike carbon (OLC) and few-layer graphene (FLG), can be prepared easily and have been utilized and researched in catalysis as carbon supports [45][46][47][48][49][50].…”

Graphitized nanocarbon materials can be an ideal catalyst support for heterogeneous catalytic systems. Their unique physical and chemical properties, such as large surface area, high adsorption capacity, excellent thermal and mechanical stability, outstanding electronic properties, and tunable porosity, allow the anchoring and dispersion of the active metals. Therefore, currently they are used as the key support material in many catalytic processes. This review summarizes recent relevant applications in supported catalysts that use graphitized nanocarbon as supports for catalytic oxidation, hydrogenation, dehydrogenation, and C-C coupling reactions in liquid-phase and gas-solid phase-reaction systems. The latest developments in specific features derived from the morphology and characteristics of graphitized nanocarbon-supported metal catalysts are highlighted, as well as the differences in the catalytic behavior of graphitized nanocarbon-supported metal catalysts versus other related catalysts. The scientific challenges and opportunities in this field are also discussed. Keywords: nanocarbon materials; graphitized carbon supports; metal catalysts; hetergeneous catalysis INTRODUCTIONCarbon combines its atoms in diverse hybridization states (sp, sp 2 , sp 3 ) to form a variety of polymorphs. These are composed entirely of carbon but have different physical structures and different names, including diamond, graphite, fullerenes, and carbines, among others [1][2][3][4][5]. Because these various and versatile allotropes produce materials with a large range of properties, carbon materials can be used in a number of technological processes, including high-tech catalytic ones [6][7][8][9][10].In heterogeneous catalysis, carbon material plays wellestablished and important roles in a wide range of applications, both as catalyst in its own right and as a unique support material [11][12][13][14][15]. The chemical stability of carbon supports in some specifically aqueous phase biomass conversion surpasses that of metal oxide materials; in addition, carbon materials present other common and key advantages as support materials for catalysis [1,5]. From the point of physical structure, porous carbon can be prepared in different forms (granules, cloth, fibers, pallets, etc.). Due to its chemical properties, carbon structure is resistant to both acidic and basic media. The structure of carbon is stable at high temperature (even above 1023 K under inert atmosphere). The hydrophilic/ hydrophobic nature of carbon can be easily modified. Active metals on the support can be easily reduced. For the purposes of industrial economy and environment, the active phase can be easily recovered. Conventional carbon supports are lower-cost and more easily available than other conventional supports. Although several kinds of carbon materials have been studied, active carbon (AC) [12,[16][17][18][19] and, to a lesser extend, carbon black [20][21][22][23] have long been the most commonly used carbon supports. AC is an amorphous solid prepa...
