@article{25917, abstract = {{Ordered, bimodal mesoporous CMK-5 carbon is prepared by using mesoporous SBA-15 silica as a structural mold. The carbon material is chemically modified by oxidative treatment with acidic persulfate solution. This leads to the creation of oxygen-containing functionalities at the pore walls of the carbon (up to 13 wt% oxygen), as confirmed by IR spectroscopy. The oxidative treatment is carried out before removal of the silica mold which ensures that only one of the two distinct modes of mesopores (namely, the intra-tubular pores) is affected; the other mode (inter-tubular pores) is protected from oxidation by the presence of the silica mold. This is proven by water vapor physisorption analysis. The oxidatively treated (intra-tubular) pores are significantly more polar and, hence, better wettable than the untreated (inter-tubular) pores.}}, author = {{Weinberger, Christian and Cao, X. and Tiemann, Michael}}, issn = {{2050-7488}}, journal = {{Journal of Materials Chemistry A}}, pages = {{18426--18431}}, title = {{{Selective surface modification in bimodal mesoporous CMK-5 carbon}}}, doi = {{10.1039/c6ta07772b}}, year = {{2016}}, }
