Hydrogen sulfide (H₂S) has a broad spectrum of properties and is particularly infamous for having toxic effects on various biosystems. The regulation of H₂S levels in ecosystems is thus important not only to safeguard public health, but to provide environmental protection. In recent years, significant efforts have been focused on solution and materials chemistry-based approaches for the removal of H₂S gas from different processes and industrial products/wastes. This paper briefly discusses the physicochemical properties and toxicology profile of H₂S. This paper is then briefly summarized, focusing on recent progress in solution chemistry-based approaches for the removal of H₂S from various sources, especially biogases, natural gases, and industrial products/wastes. A particular focus is placed on innovative research on materials chemistry for removing H₂S, along with the advantages and limitations regarding their practical application.
