Hydrogen sulfide (H 2 S) is a critical problem for biogas applications, such as electricity and heat generation, or the production of different chemical compounds, due to corrosion and toxic effluent gases. The selective catalytic oxidation of H 2 S to S is the most promising way to eliminate H 2 S from biogas due to the lack of effluents, therefore can be considered a green technology. The most extensively used catalysts for H 2 S selective oxidation can be classified in two groups: metal oxide-based catalysts, including vanadium and iron oxides, and carbon-based catalysts. Numerous studies have been devoted to studying their different catalytic performances. For industrial applications, the most suitable catalysts should be less sensitive to the operating parameters like the temperature, O 2 /H 2 S ratio, and H 2 O content. More specifically, for metal oxides and carbon-based catalysts, the temperature and O 2 /H 2 S ratio have a similar effect on the conversion and selectivity, but carbon-based catalysts are less sensitive to water in all operating conditions. • Fe 2 O 3 , V 2 O 5 , and carbon-based catalysts have a similar temperature and O2/H2S ratio sensitive on activity and selectivity. • Carbon-based catalysts are less sensitive to operating conditions when compared with vanadium and iron-based catalysts. • Iron oxide-based catalysts represent an excellent option for future development of catalysts.
