Synthesis of Nitrogen‐Doped CNT‐Based MOF Hybrids for Adsorptive Desulfurization of the Gas Stream

Abstract

In this research, hybrids of N-doped carbon nanotube (NCNT)based metal-organic framework (MOF) (NCNT/UiO-66 and NCNT/ZIF-67) were synthesized using hydrothermal method. The performance of synthesized hybrids was evaluated in hydrogen sulfide removal under a dynamic system at 30-50°C with 4500 ppm H 2 S concentration as inlet feed compared with neat UiO-66 and ZIF-67. NCNT/UiO-66 and NCNT/ZIF-67 were characterized using XRD, FTIR, FESEM, BET, and TGA. NCNT/ZIF-67 and NCNT/UiO-66 showed good adsorption capability for H 2 S with a capacity of 189.72 mg/g and 175.77 mg/g, respectively. The surface area of UiO-66 and ZIF-67 is (1351 and 1290 m 2 /g, respectively), and the addition of NCNT leads to the reduced surface area of nano adsorbent hybrids. Also, the performance of hybrids would not change after three cycles of the desulfurization process. These hybrids indicated the excellent potential for a desulfurization process.

Promotional effect of H2O introduction on the NH3-SCR activity of the gas-phase sulfated CeO2 catalyst by organic CS2+COS: Influence of H2O concentration

“…Compared to inorganic SO2, organic carbonyl sulfide (COS) and carbon disulfide (CS2) are linear triatomic molecules similar to carbon dioxide (CO2), which are less reactive and difficult to be removed [11,12]. At present, catalytic hydrolysis [13,14], hydrogenation [15,16], adsorption and absorption [17][18][19] have been developed to reduce the emission of organic sulfur.…”
