Abstract

Removing hydrogen sulfide (H2S) from the air stream in the workplace is important because this toxic gas can cause health problems for workers and destructive effects on equipment. Metal-organic frameworks (MOFs) are one of the most suitable materials for H2S removal and separation. This review study attempted to comprehensively collect the studies and research regarding the removal of H2S from the air stream using MOFs as an effective adsorbent. The databases of Google Scholar, Pub-Med, Scopus, and Web of Science were used in this study. All sections of the articles were reviewed to extract the required data. Keywords such as hydrogen sulfide, metal-organic frameworks, air purification, removal, and adsorption were used to extract the relevant articles. The results showed that UIO-66 and TOUO were the most commonly used MOFs for H2S absorption. The average H2S absorption among all MOFs was 14.92 mg/g. Advances in MOF design, stability, regeneration efficiency, and process integration further enhance their performance, making them more attractive for industrial-scale applications in gas purification and other separation processes. This review article could provide useful information and insight into the remarkable progress in the field of H2S adsorption by MOFs.
