“…Through irradiating LED on the biochar@ZnO-Ce nanocatalysts, photons with an energy similar to or more than the band gap are absorbed, and it induces the stimulation of electrons from the valence band to the conduction band. Hence, by drawing (𝛼ℎ𝑣) 2 versus ℎ𝑣 and with the assistance of linear extrapolation, band gap quantities are attained. It can be observed in Figure 8 (b) that with the incorporation of ZnO-Ce nanoparticles into biochar, the band gap of the composite has dwindled from 3.31 to 2.96 eV.…”

In this work, the photocatalytic removal of reactive blue 19 (RB19) dye was investigated by employing ZnO-Ce nanoparticles decorated with biochar under LED irradiation. Synthesis of ZnO-Ce nanoparticles decorated with biochar was performed utilizing the co-precipitation procedure, and the texture and morphologyof the fabricated nanocomposite were analyzed using EDX, FESEM, XRD, TEM, BET, and FTIR techniques. Moreover, FESEM images demonstrated that ZnO-Ce nanoparticles were successfully decoratedon the surface of biochar. The specific surface areas of biochar and biochar@ZnO-Ce were 34.518 and 636.52 m2/g, respectively. To achieve the maximum yield in the removal of RB19 dye, the influence of operating variables including dye concentration, LED lamp power, biochar@ZnO-Ce catalyst dose, pH, and H2O2dose were explored. Besides, the maximum percentage of RB19 dye removal was 96.47% under optimal conditions, i.e. catalyst dosage of 100 mg, H2O2 dosage of 1 mL, pH of 9, initial dye concentration of 5 ppm, LED power of 50 W, and reaction time of 140 min. Also, the kinetic information revealed that the removal of RB19 dye was in accordance with the pseudo-first order kinetic model, and the reaction rate constant and correlation coefficient were determined to be 0.045 min− 1 and R2 = 0.990, respectively. Also, the recyclability of biochar@ZnO-Ce nanocatalysts was promising over five runs, and only 6.08% of RB19 dye removal efficiency decreased. Therefore, it can be concluded that the biochar@ZnO-Ce photocatalyst can be promisingly applied for the removal of azo dyes in the aqueous solutions.

“…These substances can affect the light activity of aquatic plants by reducing light penetration, causing eutrophication, increasing suspended solids, and increasing turbidity in water bodies [2,3]. Some dyes also degrade in wastewater under anaerobic conditions to form aromatic amines, which can be hazardous to human and animal health.…”

Currently, the primary focus for scientific authorities and regulatory departments revolves around water pollution. In this regard, photocatalysis has emerged as a highly effective, affordable, and goal‐oriented approach. Thus, recognizing the urgency of this issue, we focused our efforts towards developing a novel ternary photocatalytic structure based on mesoporous SrSnO3, combined with polypyrrole‐doped carbon black (PPC) and platinum nanoparticles (Pt NPs). Pt NPs, PPC and SrSnO3‐based nanocomposite photocatalyst was developed through a very simple chemical method followed by ultrasonication and photoreduction techniques. XRD analysis confirmed orthorhombic phase of SrSnO3, while the formation of the ternary nanocomposite among Pt NPs, PPC and SrSnO3 has been confirmed by X‐ray photoelectron spectroscopy (XPS) and Fourier Transform Infrared (FTIR) spectroscopy. Transmission electron microscopy (TEM) revealed the presence of Pt NPs (5–15 nm), beads/dense cocoon like structures of PPC along with rod, spherical and needle shape nanostructures of SrSnO3 in newly created ternary photocatalyst. Diffuse reflectance spectroscopy (DRS) showed lowering of band gap energy in case of Pt@PPC/SrSnO3. Newly developed Pt@PPC/SrSnO3 nanocomposite worked efficiently when employed on colorless insecticide imidacloprid (IMD) and on colored methylene blue (MB) dye under UV‐light. Pt@PPC/SrSnO3 photocatalyst exhibited excellent performance with 96.03 % removal of pollutant IMD in only 20 min, almost 296 % more efficient than bare SrSnO3. Furthermore, the Pt@PPC/SrSnO3 ternary photocatalyst showed rapid removal of MB with almost total elimination of dye molecule in just 16 min.

Cationic dyes present in industrial effluents significantly reduce the effectiveness of remediation operations. Considering the terrible impact of these pollutants on environment and biodiversity, investigating strategies to remove potentially harmful compounds from water is becoming an increasingly intriguing issue. In this work, we employed a simple hydrothermal technique to synthesize Fe-doped CdO (2, 4, and 6 wt %) nanostructures and assessed their efficacy in degrading methylene blue (MB) dye and inhibiting the growth of Staphylococcus aureus and Escherichia coli, respectively. Structural, morphological, and optical characterization of produced nanomaterials was also performed using X-ray diffraction, TEM, and UV absorption spectra. The photocatalytic decomposition of MB was significantly enhanced (58.8%) by using Fe (6 wt %)-doped CdO catalysts for 80 min under irradiation. In addition, 2.05−5.05 mm inhibitory zones were seen against Gram-positive bacteria (S. aureus), whereas the range for Gram-negative bacteria (E. coli) was 1.65−2.75 mm. These nanostructures were shown to be very effective inhibitors of beta-lactamase, D-alanine-D-alanine ligase B, and fatty acid synthase inhibitor by in silico molecular docking investigations.
