Recent advances in catalytic oxidative desulfurization of fuel oil – A review
Abdurrashid Haruna,Zulkifli Merican Aljunid Merican,Suleiman Gani Musa 한국공업화학회 2022 Journal of Industrial and Engineering Chemistry Vol.112 No.-
Sulfur affects fuel quality, and the burning of fuel containing sulfur compounds caused adverse effects onhumans and the environment. Nowadays, research has shifted focus to the development of desulfurizationtechnologies to cut the sulfur content to permissible limits for gasoline and diesel. Although varioustechnologies developed for oil treatment in petrochemical industries are not very effective and unable tocomply with the standard recommended values. In recent times, catalytic ODS has been identified as oneof the most suitable, effective, and sustainable technology for deep desulfurization. The development ofnew emerging class of hybrid organic–inorganic compounds of POM@MOF demonstrated great potentialas catalytic materials for ODS. This is due to the unique characteristics of high functionalization, stability,surface area, and porosity. This review provides an overview of sulfur-containing compounds in fuel andpresents a critical analysis of desulfurization methods and applications. This is followed by an in-depthanalysis of the recently developed strategies of POM@MOFs applications considering the emerging prospectsand advantages to overcome the drawbacks of pristine POMs and MOFs. The operating parametersaffecting catalytic activity have been discussed, and finally, the work provides future research directionsto increase the catalytic performance of POM@MOFs materials in desulfurization technology.

The application of halloysite nanotubes (HNTs) in water purification is attracting extensive attention because they are inexpensive raw materials with a hollow nanotubular structure in the sub-micrometer range, a large specific surface area, pore volume, pore size, and adequate hydroxyl groups on their surface, thus enhancing their ability to be modified. These modified halloysite nanotubes (m-HNTs) have been widely used for a variety of applications, including chemocatalysis, biocatalysis, antibacterial action, drug delivery, gas separation, and adsorbents for wastewater treatment. They were reported to have been produced using a variety of synthetic processes which include self-assembly/vacuum filtering, extraction, solution casting, dehydration condensation, thermal polycondensation, chemical vapor deposition, and hydrothermal carbonization. In this review, we focus on the compilation of the most recent developments in the manufacture of m-HNTs, their characterization and possible uses in wastewater treatment. Finally, we present our personal views on the opportunities and challenges of future researches involving m-HNTs, hoping to inspire more researchers into participating in this fascinating area.
