“…Researchers reported that metal oxides supported over AC have drawn interest because it could do the job simultaneously in a single step process. Many types of metal oxides have been studied, including Fe, Mn, Ca, V, Cu and Cr oxides in comparison to AC alone but so far none have reported on cerium (Ce) [6][7][8][9][10][11][12][13].…”

“…In this context, numerous studies have tested activated carbon, due to their unique characteristics, for example, large specific surface area, uniform pore size distribution, and amenability to surface function [5,7,8]. Recent studies have shown that activated carbon loaded with metal oxide or the surface functionalized with a suitable reagent is more efficient with respect to the catalytic oxidation of SO 2 [9][10][11].…”

ZnFe 2 O 4 /AC composites were prepared by the one-pot hydrothermal method using the activated carbon (AC) as a carrier. e synthesis conditions were optimized by a single-factor experiment. e structural, textural, and surface properties of the adsorbent have been comprehensively characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier-transform infrared (FT-IR) spectroscopy, Brunauer-Emmett-Teller (BET) measurements, and X-ray photoelectron spectroscopy (XPS) analysis. e SO 2 removal capacities of the composites were investigated via testing the adsorption capacity at the self-made desulfurization equipment. e results show that the adsorption capacity of ZnFe 2 O 4 /AC composites is much higher than that of the AC and ZnFe 2 O 4 samples, respectively. e composite overcomes the disadvantages of the traditional sintering, showing a very high desulfurization performance. e breakthrough time was 147 min, and the sulfur adsorption capacity could reach 23.67% in the desulfurization performance test.

“…Selective catalytic reduction (SCR) has been an attractive method for NO reduction because of its high control efficiency, low reaction temperature, and low energy/fuel requirement. Many studies have applied SCR for NO reduction and the feasible catalysts include transition metal catalysts (Cu, Fe, V, Co and Ni) supported by activated carbon [1,2], noble metal catalysts (Pd-Rh) supported on alumina [3] and some combined/modified metal catalysts (Pd-Na and Rh-Na) [4][5][6][7].…”

The effect of Na addition on the performance of Rh/Al 2 O 3 catalyst for NO reduction with CO in the presence of H 2 O and O 2 was investigated. The reacted catalysts were analyzed by the FTIR technique to identify the products for further investigation on the possible catalytic reaction mechanisms and the reasons behind the H 2 O poisoning. Experimental results show that the removal efficiency of NO by Rh/Al 2 O 3 catalyst was 63% at 250°C but that decreased as the H 2 O content increased. Adding Na to modify the Rh/Al 2 O 3 catalyst significantly enhanced the conversion of NO to 99% at 250-300°C even as the H 2 O content was 1.6 vol%. The FTIR analyses results reveal that the abundant H 2 O in the flue gas can compete with NO to adsorb on the surfaces of Rh/Al 2 O 3 and Rh-Na/ Al 2 O 3 catalysts and further enhance the formation of NO 3 that reacts with H. The effects of H 2 O on Rh/Al 2 O 3 and Rh-Na/Al 2 O 3 catalysts can be eliminated by increasing the reaction temperature to higher than 300°C. Rh-Na/Al 2 O 3 is a feasible catalyst for NO reduction at such condition with relative high H 2 O and O 2 contents.
