“…The desulfurization solution used for the experiments was prepared in the laboratory, referring to our previous work (Liu et al, 2022). Its main components were 40 ml of N-methyl pyrrolidone (NMP) and 1 g of antimony chloride (SbCl 3 ).…”

“…Here, the reusability and stability of the catalyst were evaluated by the sulfur capacity level of the desulfurization solution and the iron content on the catalyst after regeneration. After the catalyst is added to the desulfurization solution, the following oxidationreduction reactions will occur in the solution (Liu et al, 2022;Qiu et al, 2022). Fe 3+ oxidizes the H 2 S originally absorbed by the coordination state to sulfur and removes it separately.…”

“…The former is generally applicable to low-sulfur gas purification and the latter one suffers from low sulfur capacity, easy solvent degradation, affluent generation, and poor sulfur quality (Qiu et al, 2022). In addition, the most widely used organic iron-based wet desulfurization solution can easily lead to H 2 S oxidation and thereby lead to sulfur blockage in the reactor and pipeline accumulation (Liu et al, 2022). Currently, this phenomenon is widespread in high-pressure and high-sulfur-content scenarios.…”

“…Its application to small-scale high-pressure industrial gas desulfurization can greatly simplify the well site desulfurization process and effectively achieve green, efficient, and economic sulfur-bearing wellhead gas capacity release (Gu et al, 2008). The antimony-based organic nonaqueous phase desulfurization system developed in our previous work (Liu et al, 2022) is effective in removing H 2 S from gas streams through ligand absorption.…”

To solve the problem of pipeline blockage caused by sulfur deposition in industrial gas wet oxidative desulfurization operations, this study developed an iron-modified chitosan catalyst for the catalytic oxidation regeneration of conventional wet oxidative desulfurization-rich liquids. Detailed characterization results show that Fe3+ species are successfully coordinated with the chitosan substrate. The results of desulfurization and regeneration experiments showed that the Fe3+-modified chitosan could effectively regenerate the desulfurization waste stream and remain stable in the acidic desulfurization stream. The powdered iron-based modified chitosan catalyst prepared with a mass ratio of chitosan to FeCl3 of 1:5 and glutaraldehyde of 12.5% by mass has better catalytic performance than the microbead counterpart. The regeneration performance of the catalyst was evaluated by the desulfurization performance of the regenerated desulfurization solution. The iron-based modified chitosan shows a good regeneration performance, and the loss of Fe content is less than 1.5% after five runs. This study provides an efficient way to develop cost-effective catalysts for the regeneration of wet oxidative desulfurization-rich liquids.

Electrolyte additives with multiple functions enable the interfacial engineering of Li‐metal batteries (LMBs). Owing to their unique reduction behavior, additives exhibit a high potential for electrode surface modification that increases the reversibility of Li‐metal anodes by enabling the development of a hierarchical solid electrolyte interphase (SEI). This study confirms that an adequately designed SEI facilitates the homogeneous supply of Li+, nonlocalized Li deposition, and low electrolyte degradation in LMBs while enduring the volume fluctuation of Li‐metal anodes on cycling. An in‐depth analysis of interfacial engineering mechanisms reveals that multilayered SEI structures comprising mechanically robust LiF‐rich species, electron‐rich P–O species, and elastic polymeric species enabled the stable charge and discharge of LMBs. The polymeric outer SEI layer in the as‐fabricated multilayered SEI could accommodate the volume fluctuation of Li‐metal anodes, significantly enhancing the cycling stability Li||LiNi0.8Co0.1Mn0.1O2 full cells with an electrolyte amount of 3.6 g Ah−1 and an areal capacity of 3.2 mAh cm−2. Therefore, this study confirms the ability of interfacial layers formed by electrolyte additives and fluorinated solvents to advance the performance of LMBs and can open new frontiers in the fabrication of high‐performance LMBs through electrolyte‐formulation engineering.
