“…Moreover, both the carbon nanofibers with and without silver nanoparticles exhibited comparable nitrogen uptake proving that the presence of silver did not affect adsorption properties of the final material. Similar observations obtained in another set of experiments by Ryu et al (1999a) confirmed the aforementioned finding for pure carbon nanofibers and active carbon nanofibers loaded with 1000-10000 ppm of silver. Park and Jang (2002) studied the antibacterial properties of a carbonsilver composite prepared by impregnation of carbon fibers with AgNO 3 solution.…”

Soft-templating synthesis and adsorption properties of mesoporous carbons with embedded silver nanoparticles

Mesoporous carbons containing silver nanoparticles have been successfully synthesized under acidic conditions by employing resorcinol and formaldehyde as carbon precursors and triblock copolymer EO 101 PO 56 EO 101 (Lutrol F127) as a soft template. Silver nanoparticles of ∼90 nm were added to the synthesis mixture to achieve 10 wt% and 20 wt% of Ag loading in the carbon. Also, tetraethyl orthosilicate (TEOS) was introduced to the system in order to improve adsorption properties of the silvercarbon composites and to reinforce its structure. The resulting carbons with incorporated silver nanoparticles featured high surface areas, large total pore volumes and primary mesopores in the range between ∼6-7 nm.

Differently shaped carbon fibers (R-, I-, C-, Y-, and X-type) were prepared from melt-spinning of reformed naphtha cracking bottom oil precursors through various shaped spinnerets. These carbon fibers were activated by steam and activation properties were compared. The decrease of hydraulic radius resulted in the extending of the external surface area of carbon fibers. Activation energy and rate of differently shaped carbon fibers were affected by external surface area. Especially, the activation rate of tetralobal carbon fibers (X-type) appeared much larger than other shaped carbon fibers due to the smallest hydraulic radius. Adsorption capacity of tetralobal activated carbon fibers was also larger than other shaped activated carbon fibers.

“…The addition of metal-containing compounds to the precursor appears to be a particularly promising and relatively simple approach [1][2][3][4][5][6][7][8]. ACFs have been formed from isotropic pitch precursors containing transition metal compounds (e.g.…”

“…ACFs have been formed from isotropic pitch precursors containing transition metal compounds (e.g. Ag, Co, Cu ions) [1][2][3][4] and organo rare-earth metal complexes [5][6][7][8]. These metals are known to generate mesoporosity during activation.…”
