Due to their potential applications in industry and potent toxicity to the environment, sulfides and their detection have attracted the attention of researchers. To date, a large number of controlled‐potential techniques for electrochemical sulfide sensors have been developed, thanks to their simplicity, reasonable limit of detection (LOD), and good selectivity. Different researchers have applied different strategies for developing selective and sensitive sulfide sensors. However, there has been no systematic review on controlled‐potential techniques for sulfide sensing. In light of this absence, the main aim of this review article is to summarize various strategies for detecting sulfide in different media. The efficiencies of the developed sulfide sensors for detecting sulfide in its various forms are determined, and the essential parameters, including sensing strategies, working electrodes, detection media, pH, LOD, sensitivity, and linear detection range, are emphasized in particular. Future research in this area is also recommended. It is expected that this review will act as a basis for further research on the fabrication of sulfide sensors for practical applications.

“…However, the electro-oxidation overpotential of H 2 S on the bare glassy carbon electrode (GCE) is too large. [34][35][36][37][38] Moreover, other electroactive interfering substances are inevitably oxidized at a high potential, which limits the selectivity of the sensor. [33,39,40] Therefore, excessive oxidation overpotential is the crucial limitation of H 2 S electrochemical sensor.…”

A one‐step hydrothermal synthesis method was used to synthesize ferric oxide nanoparticles with unique hollow spindle microstructure, which were mixed with conductive carbon black (CCB) to construct an electrochemical sensor to realize the highly sensitive detection of trace hydrogen sulfide (H2S) in biological samples. Our findings suggested that hollow spindle ferric oxide (Hs‐Fe2O3) held good electrocatalytic activity toward H2S, which mainly depended on the coupling effect of Fe (III)/Fe (II) significantly reduced the overpotential of electro‐oxidation reaction of H2S. Importantly, the unique structure of the hollow spindle provided more catalytic active sites and more efficient mass transfer process, which effectively improved the detection performance. The proposed sensor had good sensing performances, with excellent sensitivity (2.4 times of commercial Fe2O3/CCB), low detection limit (1.86 μM), wide linear range (7.6~152 μM) and favorable selectivity. Furthermore, quantitative detection of H2S was achieved in fetal bovine serum samples, which confirmed that the sensor could become a promising strategy for detecting H2S in the pathological study of related diseases.

“…There have been several reports upon the electroanalytical sensing of sulfide within aqueous media, however many involve multiple arduous and time-consuming fabrication steps and in the majority of these reports, electrocatalysts/mediators are employed for the electrochemical sensing of sulfide; Table 1 provides a thorough overview of literature. For example, recent work has been published utilizing nano-copper screen-printed electrodes (SPEs) for the successful detection of sulfide [14].…”

Abstract:The mediatorless electroanalytical sensing of sulfide is explored at a range of commercially available graphitic based electrodes namely, edge and basal plane pyrolytic graphite (EPPGE and BPPGE, respectively), boron-doped diamond (BDDE), glassy carbon (GCE) and screen-printed electrodes (SPE). The electrochemical performance is evaluated in terms of current density/analytical signal and oxidation potential, where the GCE and SPE are found to possess the optimal electrochemical responses. The electroanalytical performance of the GCE is explored towards the electrochemical sensing of sulfide and it is found that it is hampered by sulfide passivation, thus requiring pretreatment in the form of electrode polishing between each measurement. We demonstrate that SPEs provide a simple analytically comparable alternative, which, due to their scales of economy, create disposable, one-shot sensors that do not require any pretreatment of the electrode surface. To the best of our knowledge, this is the first report using mediatorless SPEs (bare/unmodified) towards the sensing of sulfide. In addition, the electroanalytical efficacy of the SPEs is also explored towards the detection of sulfide within model aqueous solutions and real drinking water samples presenting good apparent recoveries, justifying the plausibility of this graphitic mediatorless screen-printed platform.
