“…Yin et al [ 52 ] used a copper gallate spinel (CuGa 2 O 4 ) modified GCE as a H 2 O 2 sensor and obtained a LOD of 5 µM. Bohlooli et al [ 53 ] developed a manganese oxide (MnOx)/carbon nanowall based non-enzymatic H 2 O 2 sensor whereas Xiao et al [ 54 ] developed a H 2 O 2 sensor and reported on MnO 2 -carbon nanofibers (CNF)/GCE as the H 2 O 2 sensor. In other work, copper bismuth oxide was prepared on a fluorine doped tin oxide (FTO) substrate and used as a H 2 O 2 sensor, which exhibited a LOD of 380 µM [ 55 ].…”

In recent years, the electrochemical sensing approach has attracted electrochemists because of its excellent detection process, simplicity, high sensitivity, cost-effectiveness, and high selectivity. In this study, we prepared nitrogen doped reduced graphene oxide (N-rGO) and characterized it using various advanced techniques such as XRD, SEM, EDX, Raman, and XPS. Furthermore, we modified the active surface of a screen printed carbon electrode (SPCE) via the drop-casting of N-rGO. This modified electrode (N-rGO/SPCE) exhibited an excellent detection limit (LOD) of 0.83 µM with a decent sensitivity of 4.34 µAµM−1cm−2 for the detection of hydrogen peroxide (H2O2). In addition, N-rGO/SPCE also showed excellent selectivity, repeatability, and stability for the sensing of H2O2. Real sample investigations were also carried out that showed decent recovery.

“…The quantitative analysis of HPV-containing environments can be carried out by numerous techniques, such as chromatography, electrochemistry, fluorescence, chemiluminescence, chemosensory, etc. Despite the variety of methods, resistive sensors designed based on chemosensory principles (so-called chemoresistors) are advantageous due to their high sensitivity and stability, low power consumption, and relatively easy fabrication technology [ 1 , 2 , 3 , 4 , 5 ].…”

Room Temperature Detection of Hydrogen Peroxide Vapor by Fe2O3:ZnO Nanograins

In this report, a Fe2O3:ZnO sputtering target and a nanograins-based sensor were developed for the room temperature (RT) detection of hydrogen peroxide vapor (HPV) using the solid-state reaction method and the radio frequency (RF) magnetron sputtering technique, respectively. The characterization of the synthesized sputtering target and the obtained nanostructured film was carried out by scanning electron microscopy (SEM), transmission electron microscopy (TEM), and energy-dispersive X-ray (EDX) analyses. The SEM and TEM images of the film revealed its homogeneous granular structure, with a grain size of 10–30 nm and an interplanar spacing of Fe2O3 and ZnO, respectively. EDX spectroscopy presented the real concentrations of Zn in the target material and in the film (21.2 wt.% and 19.4 wt.%, respectively), with a uniform distribution of O, Al, Zn, and Fe elements in the e-mapped images of the Fe2O3:ZnO film. The gas sensing behavior was investigated in the temperature range of 25–250 °C with regards to the 1.5–56 ppm HPV concentrations, with and without ultraviolet (UV) irradiation. The presence of UV light on the Fe2O3:ZnO surface at RT reduced a low detection limit from 3 ppm to 1.5 ppm, which corresponded to a response value of 12, with the sensor’s response and recovery times of 91 s and 482 s, respectively. The obtained promising results are attributed to the improved characteristics of the Fe2O3:ZnO composite material, which will enable its use in multifunctional sensor systems and medical diagnostic devices.
