“…As a result of the pores in the zeolite structure, the amount of TiO 2 on the zeolite increased. Also, the change in the spectrum shape in the range of 600-790 cm − 1 shows that TiO 2 interacts with the pore network of zeolite (Song et al, 2017;Rahman et al, 2018). Hardly any significant change was observed in the range between 2800 and 3500 cm − 1 , which is mainly attributed to the H 2 O and CO 2 molecules adsorbed on the zeolite surface.…”

“…Metal modifications have been the common approach to enhance the sulfur adsorption capacity of FAU zeolites. It has been demonstrated that modifying the Na-Y zeolites with metals can increase the adsorption capacity up to 5 times, compared to the parent Y zeolite. ,− FAU modified with Ag, Ce, Cu, Zn, and Ni have been reported in the literature, − which is the focus of this review.…”

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.

Acting as photocatalyst carriers, their large surface area is favorable to disperse the photocatalyst powder, providing more reactive active sites, and inhibiting the photocatalyst aggregation phenomenon, which is a good choice for future researchers to design functional photocatalyst.…”

Fuel oil, the most important strategic resource, has been widely used in industrial applications. However, the sulfur‐containing compounds in fuel oil also present humanity with huge environmental issues and health concerns due to the hazardous combustion waste. To address this problem, the low vulcanization of fuel production technology has been intensively explored. Compared with traditional hydrodesulfurization technology, the newly emerged photocatalytic desulfurization has the advantages of milder operating conditions, lower energy consumption, and higher efficiency, holding great prospect to achieve deep desulfurization. Though great efforts have been made, the desulfurization catalysts still suffer from inferior light absorption, fast recombination of photocarriers, and poor structure modification. This Review summarizes recent development of photocatalytic desulfurization, including the desulfurization principle, current desulfurization challenges, and corresponding solutions. Particularly, the roles of defect engineering, hybrid coupling, and structure modifications in the enhancement of photocatalytic performance are emphasized. In addition, the photocatalytic desulfurization mechanism is also introduced with the .OH and .O2− radicals as main active species. Finally, some perspectives on the photocatalytic desulfurization are provided, which can further optimize the desulfurization efficiency and guide future photocatalyst design.
