“…6. TiO 2 displayed an absorption edge at 393 nm which is in good agreement with the previous reports [54,55]. From the figure, it is evident that the absorption edges were extended to visible light range with the incorporation of KG into TiO 2 matrix.…”

A novel solar light active photocatalyst, TiO 2 /kaolin-graphene carboxyl nanocomposite was synthesized by hydrothermal method for the degradation of cephalosporin antibiotic, cefuroxime sodium. The synthesized photocatalyst was characterized by various analytical and spectroscopic techniques, including Fourier transform infrared spectroscopy (FT-IR), powder X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX) thermogravimetry (TG), UV-Vis diffuse reflectance spectroscopy (DRS) and photoluminescence (PL). The prepared TiO 2 /kaolin-graphene carboxyl nanocomposite exhibited efficient photocatalytic degradation of methylene blue (MB) upon illumination with the solar simulator as compared to unmodified TiO 2 . The incorporation of both kaolin and graphene carboxyl was found to immobilize TiO 2 , enhancing the visible light absorption range of TiO 2 . Scavenger study revealed that hydroxyl radicals act as the main active species in the photocatalytic degradation process. The hydroxyl group present on kaolin surface reacts with photo-generated holes to increase the amount of hydroxyl radical, and further the graphene carboxyl plays a role to impede the recombination of photo-generated electron-hole pairs. Furthermore, the synthesized photocatalyst was found to degrade cefuroxime sodium within 90 min of sunlight illumination, indicating that TiO 2 /kaolin-graphene carboxyl nanocomposites would be very beneficial for pharmaceutical waste management through the advanced oxidation process. Mass spectral analysis was also carried out for elucidating the photocatalytic degradation pathway of cefuroxime sodium.

“…In operations, the redox-active sites shuttle electrons between a solution of the analyte and the substrate electrodes often along with a significant reduction of the activation overpotential. A further advantage of chemically modified electrodes is that they are less prone to surface fouling and oxide formation compared to inert substrate electrodes [31][32][33][34][35][36][37][38][39][40][41][42][43][44][45].…”

In this study, synthesis and electrochemical sensor application of flower-like MoS2 for sunset yellow FCF sensing were evaluated. Linear sweep voltammetry (LSV), chronoamperometry and differential pulse voltammetry (DPV) were used to determine flower-like MoS2 electrochemical sensor performances, which had LOD of 0.04 μM in the linear working range of 0.1–150.0 μM calculated from DPV. The sensor was successfully applied for the determination of sunset yellow FCF in real samples.

“…Electrochemical detection has the advantages of simple operation, low cost, and easy to carry, but the specific recognition of the electrochemical method in detection is poor. The chemical modification of inert substrate electrodes offers significant advantages in the design and development of electrochemical sensors [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. A further advantage of chemically modified electrodes is that they are less prone to surface fouling and oxide formation compared to inert substrate electrodes [27][28][29][30][31][32][33][34][35][36][37][38][39].…”

A novel MnO2 nanorods modified screen-printed electrode was fabricated and used as a voltammetric sensor for Sudan determination. MnO2 nanorods were characterized using Field emission-scanning electron microscopy (FE-SEM). Electrochemical measurements were performed using cyclic voltammetry (CV), linear sweep voltammetry (LSV), differential pulse voltammetry (DPV), and chronoammperometry (CA). The MnO2 nanorods on the electrode surface act as an excellent catalyst for the Sudan oxidation reaction. Our modified electrode presents good electrocatalytic activity toward Sudan, a short response time of <10 s, a low detection limit of around 0.08 µM, and linear detection range from 0.25 to 300.0 µM.
