Highly ordered mesoporous silica can be regenerated from a mesoporous carbon CMK-3 that is a negative replica of mesoporous silica SBA-15, indicating reversible replication between carbon and inorganic materials.

Ball-milled graphitic carbon, both not and electrochemically lithiated, has been studied by total x-ray diffraction involving high-energy synchrotron radiation scattering and atomic pair distribution function analysis. The experimental data has been used to guide reverse Monte Carlo simulations of the three-dimensional structure of the not-lithiated samples. Experimental and modeling results sh...

Graphitic carbon nanocoils with a high degree of crystallinity have been synthesized by using as intermediates hydrothermally carbonized samples (here denoted as hydrochar) obtained from three representative saccharides (glucose, sucrose and starch). The hydrochar samples were converted to graphitic nanocoils at moderate temperatures (900oC) using nickel nanoparticles as a graphitization cataly...

Graphitic carbon nitride materials have attracted significant interest in recent years and found applications diverse light-to-energy conversions such as artificial photosynthesis, CO2 reduction, or degradation of organic pollutants. However, their utilization synthetic photocatalysis, especially the direct functionalization C(sp3)–H bonds, remains underexplored. Herein, we report mesoporous gr...

The π-π interaction-dependent vapour pressure of phenanthrenequinone can be used to synthesize a phenanthrenequinone-confined ordered mesoporous carbon. Intimate contact between the insulating phenanthrenequinone and the conductive carbon framework improves the electrical conductivity. This enables a more complete redox reaction take place. The confinement of the phenanthrenequinone in the meso...

Hierarchical mesoporous yolk-shell structured carbon nanospheres (YSCNs) with an ordered mesoporous carbon core and a microporous carbon shell show excellent electrochemical performance with a maximal specific capacitance of 159 F g(-1).

B,N-codoped carbon nanostructures (BNCS) can serve as alternative low-cost metal-free electrocatalysts for oxygen reduction reactions (ORR). However, the compensation effect between the p- (B atoms) and n-type (N atoms) dopants would make the covalent boron-nitride (BN) easily formed during the synthesis of BNCS, leading to a unsatisfactory ORR activity. Therefore, it has been challenging to de...

In this paper, we report the synthesis and characterization of mesoporous carbons, which were obtained using SBA-15 silica as the template material and sucrose as the carbon source. The prepared silica template and mesoporous carbons were characterized by nitrogen adsorption-desorption, low angle X-ray diffraction (XRD) and transmission electron microscopy (TEM). Synthesized carbons were used t...

A hybrid structure, a graphitic nanostructures@porous carbon framework, is developed by utilizing the bimetallic zeolitic imidazolate framework-8 (ZIF-8) as a solid precursor, simultaneously templating porous carbon and growing graphitic nanocarbon in a simplified chemical vapor deposition (CVD) fashion. A ligand, 2-methylimidazolate (2MIM), in the ZIF-8 decomposes above 600 C to yield active c...
