“…A strong solid acid catalyst with high specific surface area is more desirable for hydrophobic acid-catalyzed reactions. Activated carbon, a microporous and/or mesoporous material with high specific surface area, is widely used as an adsorbant and as a catalyst support in a variety of industrial and environmental applications [14][15][16][17][18]. Activated carbon is generally produced by either physical or chemical activation.…”

A sulfonated (SO 3 H-bearing) carbon catalyst with mesoporous structure and high specific surface area is successfully prepared by impregnating the cellulosic precursor (wood powder) with ZnCl 2 prior to activation and sulfonation. The specific surface area of the porous carbon catalyst thus prepared is also found to increase with carbonization temperature to a maximum of 1,560 m 2 g -1 at ca. 773 K. Structural analyses reveal that the porous carbon catalysts carbonized at temperatures higher than 723 K contain high densities of micro-and mesopores. The porous carbon catalyst exhibits high catalytic performance for the esterification of acetic acid (343 K), the activity for which is dependent only on the acid density. The porous carbon catalyst also exhibits high catalytic activity for the benzylation of toluene, whereas non-porous sulfonated carbon has very limited activity for this reaction. The activity for the benzylation of toluene is dependent on both the specific surface area and the acid density of the sulfonated porous carbon catalyst.

“…on active carbons have been studied for removal/oxidation of hydrogen sulphide, ammonium ions, dyes etc. [1][2][3][4][5]. Among these catalysts, manganese oxides supported on active carbons have attracted much interest due to their high catalytic activities.…”

Abstract. Four series of samples containing manganese supported carbonaceous adsorbents were prepared. Samples of series AC-B, synthesised from the carbonaceous support with basic surface, were obtained with a yield of 50-60%, while manganese was loaded in amount of 1.44-1.65 % depending on applied method. The samples of series AC-A, synthesised from the carbonaceous support with acidic surface, were obtained with a higher yield (92-98%), but with small quantities of loaded manganese. Obtained results reveal the importance of surface chemistry of carbonaceous adsorbents on the manganese loading.

“…In addition, previous studies have found that the desulfurization activities of activated carbon could be improved by modification with transition metals, such as Co, Ni, Cu and V (Gao et al 2011;Guo et al 2012;Tseng et al 2003). Several procedures can be used practically to prepare activated carbon support catalysts.…”

Column activated carbons were prepared from walnut shell chars and transition metal oxide powders (i.e. Co 2 O 3 , Ni 2 O 3 , CuO and V 2 O 5 ) with blending method. Samples were characterized by N 2 adsorption-desorption, X-ray diffraction, X-ray photoelectron spectroscopy and Fourier-transform infrared spectroscopy. The texture properties of all modified activated carbons with metal oxides dosage of \5 wt% did not change evidently. The basic functionalities of these activated carbons increased relative to blank carbon. Moreover, metal species with different oxidation states coexisted on the modified activated carbons. The optimal dosage of all metal oxides was 2 wt%. The sulfur capacities of these modified activated carbons were 7.7-46.0 % higher than that of blank activated carbon and the highest occurred for V 2 O 5 modified activated carbon. The improved desulfurization performance was mainly attributed to the higher catalytic activity of the active metal oxides formed in the presence of O 2 during the desulfurization process.
