“…There is great potential in using adsorbents for deep desulfurization, because organic sulfur molecules can be captured at ambient conditions with high efficiency (Song et al., 2014; Vilarrasa-Garcia et al., 2011b; Xiong et al., 2010). It is commonly known that both π complexation and direct sulfur metal (S–M) bonds can work for adsorptive desulfurization (Danmaliki and Saleh, 2017; Khan et al., 2017; Shi et al., 2017 Song et al., 2013). Thus, active species, such as Cu 2 O (Jiang et al., 2013; Wang et al., 2009b), CeO 2 (Song et al., 2016; Xiao et al., 2013a), etc.…”

Adsorption is one of the most promising methods for desulfurization of transportation fuels, due to the strategy which enables removal of organic sulfur compounds to be conducted at ambient conditions with high efficiency. Adsorbent is the key to the adsorptive performance. Both p complexation and direct sulfur metal bonds are efficient methods for adsorptive desulfurization. For construction of these bonds, it is necessary to introduce active metal species on the support. In this work, Ce(NO 3 ) 2 was directly introduced into the assynthesized SBA-15, and high dispersion of CeO 2 nanoparticles was obtained. With the loading content of 12-46 wt%, the particle sizes of the CeO 2 NPs are in the range of 4.4-6.3 nm. The good dispersion status of CeO 2 nanoparticles is contributed to the template P123 preserved in as-synthesized SBA-15, which provides a confined space for the dispersion of CeO 2 nanoparticles. However, the large CeO 2 particles (7.0 nm) are formed for the sample originated from templatefree SBA-15. We also demonstrate that the adsorptive performance of SBA-15 is enhanced with the modification of CeO 2 nanoparticles. Besides, the performances of CeO 2 nanoparticlemodified samples stay in step with the dispersion status of the CeO 2 nanoparticles.

A Ce-modified H-Y/SBA-15 composite was synthesized using an overgrowth approach and was found to yield a relatively high performance in ADS . By coupling mesoporous silicas with zeolites, a hierarchical material with both mesopores and micropores can be produced, enhancing adsorptive performance.…”

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.
