Nanofeatures of resorcinol–formaldehyde carbon microspheres

The Effect of Chitosan’s Addition to Resorcinol/Formaldehyde Xerogels on the Characteristics of Resultant Activated Carbon

“…Then, the sample was heated up to a temperature of 500 °C with a heating rate of 10 °C/min; kept at 500 °C for 3 h; and then let to cool off spontaneously to ambient temperature while N 2 gas was flowing. Afterwards, the carbonized samples were activated in the same tube furnace (after cleaning it comprehensively from the residues of the carbonization process) with carbon dioxide gas flow (150 cm 3 /min) instead of N 2 gas; heating of the sample again with a rate of 10 °C/min to 700 °C; keeping it at this temperature for 1 h; and then letting the sample to cool down spontaneously to ambient temperature while flowing CO 2 gas [24]. After carbonization and activation processes of each RFX-CS-n (where n corresponds to the designated sample number), each corresponding activated carbon sample was called RFX-CS-AC-n, where n is the same number as the precursor RFX-CS-n [23] and corresponds to the concentration of Cs in the starting solution (Table 1).…”

Synthesis of carbon xerogel nanoparticles by inverse emulsion polymerization of resorcinol–formaldehyde and their use as anode materials for lithium-ion battery

“…[12][13][14] On the other hand, carbon xerogel microspheres as produced by subcritical drying did not receive considerable attention in the literature till recently as they are largely nonporous and have less surface area. 10,11,19 In this work, we report a facile way to synthesize interconnected carbon xerogel nanoparticles by repetitive inverse emulsion polymerization of RF gel followed by subcritical drying followed by pyrolysis in the nitrogen atmosphere. [15][16][17][18] Recently, carbon xerogels with varying morphology like fractallike structures and microspheres with nanofeatures have also been reported to expand their horizons for wider range of engineering applications due to their large external surface area.…”

Dataset on the new recipe for the preparation of nanoporous carbon nanorods using resorcinol-formaldehyde xerogels

“…Upon drying at atmospheric conditions, the samples were carbonized in a flowing stream of nitrogen gas, and then activated physically in a flowing stream of carbon dioxide gas. The resulting resorcinol-formaldehyde activated carbon xerogels (RF-ACXs) prepared at the gelation temperatures of 70 °C and 85 °C are coded as RF-ACX-1 and RF-ACX-2, respectively [1] , [2] .…”

“…The sample was maintained at 500 °C K for 3 h, and then allowed to cool to room temperature while passing nitrogen. The resulting carbon xerogel was then activated in the same tube furnace with CO 2 flow (150 cm 3 /min) instead of nitrogen, heating the sample again with a rate of 10 °C/min to 700 °C, maintaining this temperature for 1 h, and then allowing the sample to cool down to room temperature while passing CO 2 [2] .…”
