“…Material synthesis: We synthesized CDC from commercially available powders of B 4 C, [17] ZrC, [18] TiC, [20] and SiC [19] at various temperatures in the 400-1200°C range. TiC, ZrC and B 4 C with the average particle size of ∼ 2-4 µm were obtained from Alfa Aesar, while β-SiC powder with the average particle size of ∼ 2 µm was obtained from Superior Graphite.…”

Cryoadsorption is a promising method of enhancing gravimetric and volumetric onboard H 2 storage capacity for future transportation needs. Inexpensive carbide-derived carbons (CDCs), produced by chlorination of metal carbides, have up to 80 % open-pore volume with tunable pore size and specific surface area (SSA). Tuning the carbon structure and pore size with high sensitivity by using different starting carbides and chlorination temperatures allows rational design of carbon materials with enhanced C-H 2 interaction and thus increased H 2 storage capacity. A systematic experimental investigation of a large number of CDCs with controlled pore size distributions and SSAs shows how smaller pores increase both the heat of adsorption and the total volume of adsorbed H 2 . It has been demonstrated that increasing the average heat of H 2 adsorption above 6.6 kJ mol -1 substantially enhances H 2 uptake at 1 atm (1 atm = 101 325 Pa) and -196 °C. The heats of adsorption up to 11 kJ mol -1 exceed values reported for metal-organic framework compounds and carbon nanotubes.

“…It involves infiltration of the pores of the template with appropriate carbon precursor, carbonization, and subsequent template removal. Great progress in fabrication of MMC has been made by developing various templates, such as zeolites and silica [11,2,12]. But it usually takes a long time to synthesize and requires strong corrosive acid or concentrated alkali to dissolve these templates.…”

a b s t r a c tWe present here a novel, low cost and environmental-friendly synthetic strategy for fabricating flowerlike magnetic mesoporous carbon (MMC) microspheres by using silica coated ), as well as good chemical inertness and mechanical stability. The MMC spheres were used to adsorb 2,4,6-trichlorophenol (TCP) from simulated water samples. Experiment results suggest that the adsorption was favorable at acidic pH and increased with the rise of initial TCP concentration and temperature. Kinetic parameters were proved to follow the pseudo-second-order kinetics model and the equilibrium data was more favorable for Freundlich isotherm. The equilibrium absorption capacity was 210 mg g À1 at initial TCP concentration of 20 mg L À1and increased to 587 mg g À1 when the initial TCP concentration was up to 100 mg L À1, which was much higher than those of other carbon-based adsorbents reported in literature. To the best of our knowledge, this is the first report on the synthesis of flowerlike MMC material by using LDH as template and its application as adsorbent to remove TCP.

“…Carbide-derived carbon (CDC) synthesis is a method of growing carbon composite layers on carbide materials such as TiC and SiC. CDC layers have recently been produced by selectively etching metal components in carbide materials such as SiC, 4) TiC, 5) Ti 3 SiC 2 , 6) B 4 C, 7) ZrC, 8) MoC, 9) NbC, 10) VC, 11) and WC. 12) CDC layers may consist of amorphous carbon, crystalline graphite, nanocrystalline diamond, and carbon sheets (i.e., graphene), depending on the synthesis conditions.…”

We reviewed the current research on carbide-derived carbon (CDC) for tribological applications. Carbon materials have been produced using CDC synthesis, in which the metallic components of carbides are selectively etched using high-temperature chlorination. The CDC materials show superior material properties for various applications. SiC is the most widely used carbide, so it was the main focus of the discussion. CDC films show various synthesis-parameter-dependent crystal structures, which affect the mechanical and electrical properties. We discussed the effects of CDC synthesis parameters including adding hydrogen, choosing an appropriate reaction temperature, using catalysts, and modifying the substrate surface with a gradient carbon layer on the structures and tribological properties of CDC layers. The reactions between chlorine gas and the metal components of carbides require the proper reaction temperature because the bonding strengths of carbide materials are unique. CDCsynthesized carbon materials show excellent mechanical and physical properties, which can be continuously enhanced by innovatively modifying various synthesis parameters and by combining CDC materials with other materials. Therefore, CDC materials show great potential for being used in a broader range of applications, and they may lead to new and extended applications for ceramic materials.
