Abstract

Schematic illustration of the design for the synthesis of hierarchical-AgX. (a) Sequential acid–alkali treatments of NaX; (b) silver supported on original NaX; (c) silver supported on hierarchical NaX after sequential acid–alkali treatments.

“…Zeolites with smaller pore sizes (micro pore, 1.60 nm) are estimated to be more effective at removing sulfur compound molecules with smaller molecular weights. This aligns with previous studies indicating that zeolites with ∼1 nm diameter cannot efficiently eliminate larger organic sulfur molecules (Dehghan & Anbia, 2017; Jiang et al., 2021). In the case of Z‐Ag, as the pore size increases, it becomes possible to remove larger sulfur compounds.…”

“…However, after the synthesis of Ag, deodorization performance was not observed for AMS, whereas it exhibited 5.4% for DMDS, 52.9% for AMDS, and 74.6% for DADS. Zeolites with regularly arranged micropores selectively adsorb molecules that pass through the pores based on pore size, and selective adsorption occurs among the molecules that have passed through due to differences in reactivity (Hartmann et al., 2016; Jiang et al., 2021). Zeolites with smaller pore sizes (micro pore, 1.60 nm) are estimated to be more effective at removing sulfur compound molecules with smaller molecular weights.…”

“…and sizes. Zeolites present remarkable thermal, mechanical, and thermal properties, as well as the ability to perform ion exchange on surface active sites, which significantly boosts their adsorption capacity and selectivity towards S-or N-compounds [76].…”

“…Hence, other methods have been introduced to remove sulfur-containing compounds, such as adsorptive desulfurization (ADS), oxidative desulfurization (ODS), biodesulfurization (BDS), and extraction desulfurization (EDS). ADS is often applied for the desulfurization of porous materials, metal–organic frameworks (MOFs), − zeolites, porous carbon materials, − and porous metallic oxides, − and so on . However, after the adsorption reaction, the adsorbing materials undergo complex processing.…”
