Hydrothermal-Dependent Synthesis of Exfoliated Nickel Cobaltite Layers for Simultaneous Determination of IARC Group 2B, 3B Carcinogens

Abstract

This article describes a more accurate, reliable, and responsive electrochemical sensor for the specific analysis of major isomers of dihydroxybenzene at binary metal oxide, nickel cobaltite (NiCo 2 O 4 ) nanosheets. In this sustainable synthesis, we report the obtention of NiCo 2 O 4 (NCO) sheets prepared through the temperature-controlled hydrothermal route which yields NCO I (stacked sheets), NCO II (multilayered sheets), and NCO III (thin sheets). Then, the structural, morphological, and chemical properties were analyzed via, microscopic, diffractive, spectral studies, while the electrocatalytic activity was examined through voltammetric analysis. The electronic structure gained via hydrothermal treatment and analytical findings reveals the appropriate band position of the produced NCO sheets to be used in electrocatalytical methods. Hence, the designed sensor was evaluated to sense the major isomers of dihydroxybenzene, which pollutes the aquatic ecosystems. Therefore, for results the hydrothermally prepared NCO sheets through the temperature-controlled hydrothermal route were employed to sense the isomers of dihydroxybenzene specifically in real-time.

Novel Photoelectrochemical Biosensing Platform Based on a Double Type II CdLa2S4/SnIn4S8/Sb2S3 Ternary Heterojunction as Photoactive Materials and NiCo2O4 Nanospheres as a Photoquencher for CA19-9 Detection

“…NiCo 2 O 4 is a typical transition metal oxide with a spinel structure, which has the advantages of low cost, good conductivity, high content, and excellent stability . NiCo 2 O 4 has attracted much attention in the field of catalysis on account of its unique, bimetallic element synergistic effect, , controllable morphological properties, tunable band gap, and good electron transfer properties compared to single oxides . According to research reports, NiCo 2 O 4 with superior electrochemical performance has been rarely studied in the field of PEC immunosensor.…”

“…These included NCO I (stacked sheets), NCO II (multilayered sheets), and NCO III (thin sheets), as shown in Figure 7. The hydrothermal treatment led to modifications in the electronic structure of the NCO sheets, and subsequent analytical investigations confirmed the suitable band position of these sheets for utilization in electrocatalytic methods [159] …”
