“…Zn/Co@C was prepared using a carbonization method with an optimal carbonization temperature of 800 °C and possessed suitable porous structures, uniformly distributed metal active sites, a high surface, and large pore volume. [44] In the other work, MOF-restricted high-temperature carbonization auto reduction method was employed by Huo's team for the preparation of CuZn@C, via carbonizing a ZIF-8 grown on CuO nanosheets. Using this strategy efficiently, molded π-complexation with sulfur compounds led to simplifying the progression of adsorptive desulfurization performances.…”

Removal of sulfur-containing compounds from liquid and gas steams originated from various processes of chemical industries would be essential, since these compounds can be the principal sources of deterioration and environmental degradation, and pollution even at low threshold concentration levels. The metal-organic frameworks (MOFs) compromise a wideranging of chemical structure designs with adjustable pore size and high promising surface area for the desulfurization process.In this review study, the current published studies and researches about sulfur removal in liquid and gas purification processes using MOFs as highly effective adsorbents and catalysts are systematically gathered and compared. According to the broad contextual information for sulfur removal using different MOFs in this study, it is called for new insight windows opened for the advance progresses in this area and the project of new and more effective MOF-based sorbents.

“…According to the Lewis acid-base theory, most of the thiophene sulfur compounds in fuel are Lewis bases. 58 DBT is a kind of Lewis base, which is easy to adsorb at the center of Lewis acid. The higher the content of acidic compounds in the oxygen-containing functional groups on the surface of activated carbon, the stronger the acidity.…”

“…The heavy oil is further upgraded in the fluid catalytic cracking unit to produce high‐quality fuel products, such as diesel. However, if these organic sulfides are not treated, the sulfur can be retained into the diesel product, eventually causing acid rain and smog 4‐6 . Thus, it is of great importance to upgrading the feed to clean fuel products 7,8 .…”

“…Currently, the adsorption desulfurization technology is emerging as an attractive candidate for the sulfide treatment and can be applied after heavy oil cracking (as shown in Scheme 1). 1 As the pivotal unit, many kinds of adsorbents, such as zeolites, 9,10 mesoporous silica, 11‐13 metal oxides, 14,15 metal–organic frameworks, 16,17 and carbons, 4,18‐21 have been developed and investigated for the adsorption of aromatic organosulfur compounds from fuel. Although some progress has been made, there are still challenging issues existing in these adsorbents mentioned above, for instance, insufficient capacities, weak surface interaction, inferior stability, and so on 19 .…”

Separation of aromatic organosulfur compounds is vital for upgrading the feed to clean fuel products, however, it remains a formidable challenge for the present adsorbents. Herein, a series of novel aerogel‐like boron carbon nitride (BCN) with three‐dimensional interconnected porous networks were fabricated via a hydrogel template and freeze‐casting strategy. The as‐prepared aerogel‐like BCN had a variable carbon content and a flexible size of graphene domain on its porous structure. The optimal BCN aerogel represents the top‐level of adsorptive desulfurization (ADS) capacity for aromatic organosulfur compounds (30.8 mg S/g adsorbent), strikingly higher than the state‐of‐the‐art aerogels adsorbents (17.1 mg S/g adsorbent) reported under similar conditions. A selective adsorption for dibenzothiophene in the presence of aromatic hydrocarbons, nitrogen compounds were also achieved on BCN aerogel. The adsorption isotherm and XPS measurement reveal heterogeneous adsorption on the BCN aerogel via π–π and Lewis acid–base interactions.
