Adsorption of lysozyme on spherical mesoporous carbons (SMCs) replicated from colloidal silica arrays by chemical vapor deposition

Growth of Polyaniline on Hollow Carbon Spheres for Enhancing Electrocapacitance

“…[38][39][40] Moreover, the pore volume at a relative pressure of 0.99 was calculated to be 3.56 cm 3 /g, in which 0.18 cm 3 /g was contributed by the micropores, according to the alpha-s plot analysis (see Table 1). These results suggest that the obtained HCS were generated by a surface-templating mechanism, 33,34 which allows a thin layer of carbon films to be deposited on the surface of the template. As a result, the carbon replicas displayed larger surface areas and pore volumes than those prepared via the volume-templating mechanism.…”

“…Colloidal silica spheres with a solid core and mesoporous shell were synthesized according to the previous recipe, in which the tetraethylorthosilicate and octadecyltrimethoxysilane were applied as a silica precursor and a porogen agent, respectively. The synthetic method of the hollow carbon spheres was similar to our previous procedures, , using silica spheres with a solid core/mesoporous shell as the template and ferrocene as the precursor. After chemical vapor deposition (CVD) at 550 °C for 60 min, the as-synthesized silica/carbon composites were annealed at 800 °C for an additional 90 min, to promote graphitization of the carbon materials.…”

Mesoporous carbon nanospheres with an excellent electrocapacitive performance

“…3b displayed three well-developed peaks centered at 0.7 nm, 1.4 nm and 2.7 nm, which correspond to the adsorption of N 2 in ultrafine micropores, micropores and mesopores, respectively. Taking into account the pore confinement of silica template coupled with the surface-templating property of ferrocene when applied as a carbon precursor, 23,24 the micropores of 1.4 nm in the carbon nanospheres were most likely generated by the mesopores of 2.2 nm in the silica template (Fig. S1 †) via a surface-templating mechanism, by which the nanopores of silica were not completely filled by the pyrolytic carbon.…”

“…The mesoporous carbon nanospheres (MCS) were prepared by using the chemical vapor deposition (CVD) method with the calcined MSS as the template and ferrocene as the carbon precursor. 23,24 Typically, about 1.0 g of MSS was loaded on a quartz boat, which was placed in the center of a quartz tube heated by a furnace. The sublimation and the pyrolysis of the ferrocene were conducted in N 2 flow at 120 C and 550 C, respectively.…”
