Cyclic voltammograms of H₂S at the Pt microdisk electrode (diameter = 100 μm) in different electrolytes. (A) is [bmim][BF₄]; (B) is [C₃OHmim][BF₄]; (C) is [C₃OHmim][BF₄] with MEA and atmospheric gases and (D) is a comparison of cyclovoltamograms between [C₃OHmim][BF₄] and [C₃OHmim][BF₄] with MEA. Scan rate: 50 mV s⁻¹; the circle indicates the open cell potential (OCP) of each system, and the arrow indicates the start direction of the potential scan from OCP.
