The structure of onset phase of coal derived natural graphite (CDNG for short), semi-graphite, and CDNG subjected to different metamorphic grade were investigated using XRD, Raman spectroscopy, and HRTEM to trace their structural evolution during graphitization. The transitional phases with different structural order exist in graphite field. A classification of these transitional phases is of particular...
Millimeter-to-centimeter scale vertically aligned carbon nanotube (VACNT) arrays are widely studied because of their immense potential in a range of applications. Catalyst control during chemical vapor deposition (CVD) is key to maintain the sustained growth of VACNT arrays. Herein, we achieved ultrafast growth of VACNT arrays using Fe/Al2O3 catalysts by ethanol-assisted two-zone CVD. One zone was...
A simple method was proposed to prepare a high surface area and hierarchical porous carbon for supercapacitors by one step carbonization-activation of poly (vinylidene chloride) with NaOH. The porous carbon has hierarchical micropores, mesopores and macropores with a high surface area of 2815m 2 g −1 . Its capacitance reaches 376 and 215Fg −1 at current densities of 0.05 and...
Animal bone, an abundant biomass source and high volume food waste, had been converted into a hierarchical porous carbon in a simple two-step sustainable manner to yield a highly textured material. The structures were characterized by nitrogen sorption at 77K, scanning electron microscopy and X-ray diffraction. The electrochemical measurement in 7M KOH electrolyte showed that the porous carbon had...
An ultralong (1.0mm) aligned carbon nanotube (ACNT) electrode was fabricated by a cut/paste method. The electrode retains the intrinsic properties, including robust mechanical property, high surface area, and regular pore structure, of individual nanotubes. Electrochemical properties of the ACNT electrode in an ionic liquid (IL) electrolyte were studied by cyclic voltammetry, galvanostatic charge/discharge,...
Thermal shock resistance of industrial carbon anodes was studied from both the direct thermal shock test and indirect measurements of thermal shock resistance parameters derived from thermal and mechanical properties. The direct thermal shock test was conducted using the so-called arc discharge technique. In conjunction with finite element and fracture mechanics analysis, the thermal shock fracture...
