Synthesis and Electrochemical Performance of Heteroatom-Incorporated Ordered Mesoporous Carbons

Zhao, Xiaochen, Wang, Aiqin, Yan, Jingwang, Sun, Gongquan, Sun, Lixian, Zhang, Tao·2010·Chemistry of Materials

Abstract

Heteroatom-incorporated 2D ordered mesoporous carbons (OMCs) were fabricated via a one-pot organic−organic aqueous self-assembly approach, using resorcinol (R) and formaldehyde (F) as the carbon precursor and triblock copolymer Pluronic F127 as the mesoporous structure template. In this approach, RF resin, boric acid and/or phosphoric acid, and F127 underwent a self-assembly process under a strong acidic condition to form a polymer with ordered mesostructure, which was then carbonized at 800 °C in a nitrogen atmosphere to form B-incorporated, P-incorporated, or B, P-coincorporated OMCs. Nitrogen sorption, X-ray diffraction (XRD), and transmission electron microscopy (TEM) revealed that the heteroatom-incorporated OMCs possessed highly ordered mesoporous structures, uniform pore size distributions, and large surface areas ranging from 500 to 700 m 2 /g. The incorporation of heteroatoms effectively limited the framework shrinkage during the carbonization process, and simultaneously increased the surface oxygen groups in the carbons. The resulting heteroatom-incorporated OMCs exhibited superior electrochemical performances to nonincorporated counterpart when used as electrodes of supercapacitors.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
