Mesoporous Carbon Materials

Nitrogen-doped mesoporous carbon materials have been synthesized by using melamine-formaldehyde resin as carbon precursor and SBA-15 as a removable template. The structure of the materials was investigated by X-ray diffraction, BET specific surface area analysis, Fourier transform infrared spectroscopy, and thermogravimetric analysis. X-ray and BET studies confirmed that a pore nanostructure is inherited from the silica templates. Fourier transform infrared spectroscopy analysis showed N atoms are strongly bonded in the carbon structure in heterocycles or nitrile functions. These mesoporous nitrogen-doped carbon materials exhibits textural properties with BET surface areas ranging between 400 and 600 m2/g and uniform pore size(3.9 nm). The mechanism of carbonization process is studied by thermogravimetric analysis. The ratio of melamine/formaldehyde plays an important role during the carbonization process for the surface areas and textural properties, and element analysis reveals that the nitrogen content of the mesoporous carbon materials is as high as 10wt%.

AbstractIn view of rich potassium resources and their working potential, potassium-ion batteries (PIBs) are deemed as next generation rechargeable batteries. Owing to carbon materials with the preponderance of durability and economic price, they are widely employed in PIBs anode materials. Currently, porosity design and heteroatom doping as efficacious improvement strategies have been applied to the structural design of carbon materials to improve their electrochemical performances. Herein, nitrogen-doped mesoporous carbon spheres (MCS) are synthesized by a facile hard template method. The MCS demonstrate larger interlayer spacing in a short range, high specific surface area, abundant mesoporous structures and active sites, enhancing K-ion migration and diffusion. Furthermore, we screen out the pyrolysis temperature of 900 °C and the pore diameter of 7 nm as optimized conditions for MCS to improve performances. In detail, the optimized MCS-7-900 electrode achieves high rate capacity (107.9 mAh g−1 at 5000 mA g−1) and stably brings about 3600 cycles at 1000 mA g−1. According to electrochemical kinetic analysis, the capacitive-controlled effects play dominant roles in total storage mechanism. Additionally, the full-cell equipped MCS-7-900 as anode is successfully constructed to evaluate the practicality of MCS.
