“…Keeping this in mind, we gathered in Table 1 benchmark values reported for H 2 O 2 PEC sensors based on several semiconductor photoelectrodes. It shows that our LOD is lower than the ones obtained on BiVO 4 , [34,35] Si, [36] CuO [38] and CdS [39] -based photoelectrodes. In addition, our linear range, which spans 2 orders of magnitudes in concentration, is large and greater than the ones reported for TiO 2 , [28] WO 3 , [31] ZnO [32,33] and Cu 2 O [37] -based photoelectrodes.…”

“…[18,19] So far, PEC sensing has been mainly employed for the detection of biological macromolecules, [20] in immuno- [21] or apta- [22] assays and has also been explored for the detection of small organic molecules such as antioxidants [23] or glucose. [24,25] While H 2 O 2 is a widely-employed hole scavenger in the field of energy-related photoelectrochemical research (typically used to probe the upper performance of watersplitting photoanodes), [26,27] the PEC sensing of H 2 O 2 has been only reported on TiO 2 , [28][29][30] WO 3 , [31] ZnO, [32,33] BiVO 4 , [34,35] and Si [36] -based photoanodes and on Cu 2 O, [37] CuO, [38] CdS, [39] and CuInS 2 [40] -based photocathodes. Hematite (α-Fe 2 O 3 ) is a promising photoanode material due to its great abundance, low-cost, chemical stability and its high theoretical photoconversion efficiency.…”

Photoelectrochemical Sensing of Hydrogen Peroxide on Hematite

Due to its abundance and chemical stability, hematite (α‐Fe2O3) is a promising n‐type semiconductor photoelectrode. This is particularly true in the frame of the rapidly developing area of photoelectrochemical (PEC) sensing, where the short excited‐state lifetime and the small carrier diffusion length of hematite can be beneficially employed. On the other hand, H2O2 is an essential molecule for biological, environmental and industrial applications. In this article, we report a simple method to prepare photoelectroactive hematite layers on fluorine‐doped SnO2 (FTO) and we use these surfaces for H2O2 PEC sensing. The so‐created sensors allow to reliably detect H2O2 down to a sub‐μM concentration with a large linear range and a good reusability.

Electrochemical detection of hydrogen peroxide has achieved rapid development, due to the wide presence in industrial production, everyday life, bioprocess and green energy chemistry, etc. Many three‐dimensional structures have emerged as state‐of‐the‐art electrocatalysts due to their fascinating structures and electrochemical properties. This review summarizes free‐standing three‐dimensional electrocatalysts based on metal, metal oxide, carbon & silicon, and unconventional materials for detection of hydrogen peroxide with low limit of detection, wide range and fast response. The work also highlights their applications in near neutral conditions, especially their ability for single cell detection and mapping in biological environment. Further exploration into these materials together with devices design will facilitate the development of next‐generation detection technologies toward in situ and real‐time detection and contribute to wearable/portable smart detection electronics.

“…PEC sensing is an approach that relies on photo-illumination to transfer electrons between an analyte, a semiconductor, and an electrode [ 5 , 6 ] A PEC sensor harnesses light to stimulate the photoactive species on the electrode, and utilizes a photocurrent as a means to quantify the changes. Furthermore, it has numerous inherent benefits such as a simple electronic circuit and easy fabrication, and it can use a low-power light source, which results in a very low instrumentation cost [ 7 ] In order to further enhance the performance of PEC sensors, triethanolamine, ascorbic acid, and sodium sulphide are often added to the PEC detection cell as electron donors [ 8 ] Semiconductors such as TiO 2 [ 9 ] ZnO [ 10 ] and CdS [ 11 ] can be used as the photoactive materials in the PEC sensor.…”

Cadmium Sulphide-Reduced Graphene Oxide-Modified Photoelectrode-Based Photoelectrochemical Sensing Platform for Copper(II) Ions

A photoelectrochemical (PEC) sensor with excellent sensitivity and detection toward copper (II) ions (Cu2+) was developed using a cadmium sulphide-reduced graphene oxide (CdS-rGO) nanocomposite on an indium tin oxide (ITO) surface, with triethanolamine (TEA) used as the sacrificial electron donor. The CdS nanoparticles were initially synthesized via the aerosol-assisted chemical vapor deposition (AACVD) method using cadmium acetate and thiourea as the precursors to Cd2+ and S2-, respectively. Graphene oxide (GO) was then dip-coated onto the CdS electrode and sintered under an argon gas flow (50 mL/min) for the reduction process. The nanostructured CdS was adhered securely to the ITO by a continuous network of rGO that also acted as an avenue to intensify the transfer of electrons from the conduction band of CdS. The photoelectrochemical results indicated that the ITO/CdS-rGO photoelectrode could facilitate broad UV-visible light absorption, which would lead to a higher and steady-state photocurrent response in the presence of TEA in 0.1 M KCl. The photocurrent decreased with an increase in the concentration of Cu2+ ions. The photoelectrode response for Cu2+ ion detection had a linear range of 0.5–120 μM, with a limit of detection (LoD) of 16 nM. The proposed PEC sensor displayed ultra-sensitivity and good selectivity toward Cu2+ ion detection.
