“…While the weight loss of P (BVS‐SO 3 H) is nearly double of that of the other two samples which reflected that the hydrophilic property of P (BVS‐SO 3 H) is much better ascribed to the acidification step of sulfuric acid. The disintegration of acidic groups is corresponding to the second stage, P (BVS‐SO 3 Na) shows a minor advantage of thermal stability than P (BVS‐SO 3 H) and P (BVS‐SO 3 H)‐SO 3 CF 3 . Apparently, the catalyst is stable enough before 300 °C.…”

A newfangled cross-linked dual Brønsted acidic ternary mesoporous poly (ionic liquids)(MPILs) with mesoporous structure was successfully synthesized with divinylbenzene as cross linker, 1-vinyl-3-butyl imidazole bromide and sodium p-styrene sulfonate as functional group through an ordinary postmodification method and anion exchange process. A sponge-like mesoporous tunnel structure was observed and the obtained P (BVS-SO 3 H)-SO 3 CF 3 sample appeared a relatively high thermal stability, a large surface area (up to 286.8 m 2 /g) and great pore volume (0.73 cm 3 /g). The abundant dual acidic group of sulfonic acid and trifluoromethanesulfonic acid of the composite in the polymer framework impart Brønsted acidity. For the sake of demonstrating our claims, the sample has been used as a novel solid acid catalyst for the reaction of alkylation of o-xylene with styrene to 1-diphenylethane (PXE). Under optimal reaction conditions (reaction under 120°C for 3 hr, catalyst amount was 0.5 wt% of the reaction system, and the mass ratio of o-xylene/styrene was 7.5:1, a 100% conversion of styrene and 93.7% PXE yield was acquired. After four times recycle, the yield remains 53.3%. Comparing with the commercial liquid acid catalyst, it processing a higher catalytic property and recyclability. Moreover, this fresh dual acidic heterogeneous catalyst owning a promising future applied in other acidic catalytic reactions and provide a new method to modify catalyst.

This review discusses potential microporous and mesoporous materials that can address the issue of sulfur reduction via adsorptive desulfurization (ADS) with a focus on liquid fuels. During the transition to cleaner energy sources in the face of climate change, liquid fossil fuels will likely continue to provide a significant share of the world's energy demand. Fossil fuels possess a substantial amount of deleterious sulfur compounds that reduce the efficiency of energy production, damage the environment, and harm human health. There has recently been a large push to address these challenges that sulfur presents. ADS is one of the most promising techniques to reduce the sulfur content of liquid fuels in a cost-effective manner. The three key materials that have attracted a great deal of attention for their application in ADS are metal-organic frameworks (MOFs), zeolites, and mesoporous silicas. These materials have emerged as potential candidates for ADS because of their high surface area, tunable structure, and advantageous porosity. Research interest has been generated around finding unique approaches to modify these materials that increase their selectivity, stability, adsorption capacity, and reusability. A deeper mechanistic understanding of the adsorption of various sulfur compounds on these novel materials has been pursued experimentally and with the aid of models. This review seeks to discuss the recent advances made surrounding the most promising ADS materials while providing an outlook on where advancements still need to be made.

“…A very few studies have been reported that used composites to remove sulfur compounds . It has generally been reported that improvement in activity when composites are used is usually a result of the following: (i) enhancement of the volume of the composites; (ii) formation of an appropriate pore structure for the adsorption of a particular adsorbate; , and (iii) synergistic effects on the edge sites of metal species. − …”

Removing sulfur from liquid fuels has become an important issue in a global society. Modulated synthesis is known to improve the crystallinity of materials, ease of handling, control of crystallite size, and degree of aggregation. A group of adsorbents [activated carbon (AC), a novel synthesized Ni-based metal–organic framework (Ni-BDC), and composites of AC@Ni-BDC treated with different concentrations of nitric acid and modulator (formic acid)] were characterized using X-ray diffractometer (XRD), high-resolution transmission electron microscopy (HR-TEM), Fourier transform infrared spectroscopy (FTIR), Brunauer–Emmett–Teller (BET), and temperature-programmed desorption (TPD)-pyridine studies. The adsorbents were also evaluated for adsorptive desulfurization. The quantities of both AC and the modulator were observed to influence the nucleation of Ni-BDC, crystallite size, and crystallinity. The adsorption activity of the composite toward thiophene (TH) was the average of the two materials (i.e., AC and Ni-BDC), while the activity doubled toward dibenzothiophene (DBT) and 4,6-dimethyldibenzothiophene (4,6-DMDBT) with respect to the excepted average. The improved activity was attributed to enhanced pore structure, crystallinity, and synergistic effects that produced stronger acidic sites.
