For many years, due to people's attention to environmental pollution and increasingly stringent regulations and fuel standards, the scientific problem of removing sulfur compounds in gasoline has become a hot spot for researchers. However, because traditional hydrodesulfurization technology requires high temperature and pressure, and is expensive, some metal-containing adsorbents and activated carbon adsorbents still have many problems such as environmental pollution, poor stability, and poor adsorption capacity, so people need to find a More satisfactory and effective desulfurization adsorbent. Although the hexagonal phase boron nitride as a desulfurization adsorbent has shown a good adsorption effect on dibenzothiophene in gasoline, it is still not enough for potential industrial applications. Jiangsu Jun Xiong et al. used 1-butyl-3-methylimidazole tetrafluoroborate as a soft template and carbon source, and successfully obtained a new type of carbon-doped porous boron nitride after calcination under nitrogen. This carbon-doped porous boron nitride is used as an adsorbent to adsorb and remove dibenzothiophene from gasoline. The results show that this new type of adsorbent exhibits an excellent adsorption capacity of 28.17mg S/g, and it is found to be excellent The adsorption and desulfurization ability of the sorbent is derived from the more atoms exposed along the pores on the surface of the adsorbent and the strong Lewis acid-base interaction between dibenzothiophene and carbon-doped porous boron nitride.
