“…Several studies in literature have determined the k°or k s values for phenolic pollutants using the Laviron's theory. 63,[74][75][76][77][78] Briefly, using CV the modified electrode is utilized in investigating the effect of the scan rate on the anodic and cathodic peak potential for the phenolic pollutants. For reversible electrode processes, the oxidation peak potential will shift positively and the reduction peak potential will shift negatively with increasing scan rate.…”

Due to the close contingency between human health and their socio-economic well-being with regards to environmental pollution, environmental monitoring of various pollutants is global cause for concern. There is an urgent need for developing a sensing device that is capable for multiplex detections, cost-effective, rapid, sensitive, portable, and selective. With the advancement in the field of nanotechnology, nanocomposites are emerging as model modifier components for fulfilling the aforementioned needs and amplifying the electrochemical detection mechanisms. The interactions between the multiple components in the nanocomposite and their synergistic effects makes it superior and enhances the performance of the electrochemical sensor compared to when a singular nanomaterial component is used in the sensor. This review article apprises recent advances in the novel methodologies for fabrication of nanocomposites for voltammetric detection of water pollutants. The improved performance of the nanocomposite-based electrochemical sensors in detection of organic phenolic pollutants such as dihydroxybenzene isomers (DHB), bisphenol A (BPA) and 4-nitrophenol (4-NP) were highlighted. The future perspectives with challenges and strategic angles of development for the nanocomposite-based electrochemical sensors in environmental monitoring are also discussed.

“…In particular, hollow carbon spheres have received considerable attention because of their novel structure, large specific surface area, good electrical conductivity, adjustable pore size, excellent performance in supercapacitors, 19 electrocatalysis 20 and adsorption. 21 Long et al 22 synthesized hollow carbon spheres using dopamine as a precursor and a hard template method and utilized them for the electrochemical detection of catechol. Under the optimal experimental conditions, the catechol detection range of the hollow carbon spheres was 0.5–300 μmol L −1 .…”

“…One of the surface modification methods is heteroatom doping, which can improve some properties of HCSs, such as increasing catalytic active sites, electrical conductivity, edge plane defect sites, and induction of synergistic impact [51]. Nitrogendoped HCSs (N-HCSs) have shown recently commendable electroanalysis behaviours [52,53].…”

In this work, the glassy carbon electrode (GCE) surface was modified with nitrogen-doped hollow carbon spheres (N-HCSs) to achieve a new electrochemical sulphite sensor (N-HCSs/GCE) in water samples. The N-HCSs were explored for electrocatalytic behavior through voltammetric approaches using a routine three-electrode system. The findings revealed an admirable efficiency for modified electrodes towards sulphite oxidation, highlighting the effectiveness of our as-produced sulphite sensor. The differential pulse voltammetry was utilized under obtained optimal circumstances to study the as-developed sensor, the results of which underlined linear electrochemical current in relation to sulphite concentration, with dynamic range as wide as 1.0-100.0 μM and limit of detection as narrow as 0.35 μM. Moreover, N-HCSs/GCE had commendable practical applicability for sensing sulphite present in real specimens with voltammetric techniques.
