“…The Ag–Cu BNPs were fabricated using the chemical reduction method in which silver and copper solutions were added one by one to reaction mixture containing SDS colloidal particles that had sulfate ions. The stabilization of both the nanoparticles (Ag–Cu BNPs and SDS NPs) were interlinked with each other by the embedding of Ag–Cu BNPs on SDS-NPs due to the interaction between Ag–Cu + with negative charged sulfate ions and reduced using NaBH 4 to fine bimetallic nanoparticles within same unit studies are similar to Aazam and his co-workers …”

Remediation of industrial water pollution is a trending subject to date for the researchers around the globe, due to its detrimental effects on human life as well as aquatic life. Azo dyes are the largest industrial water polluters in respect of volume while anthraquinone the second largest. Therefore, humongous considerations are being enumerated for the removal and decolorization of azo (AZ) dyestuff; however, for anthraquinone (AQ) dyes, these efforts are considerably minimal; although the later one poses a greater threat to environmental contamination, because of their reinforced structure. The current study is an effort toward this foremost issue. Chemical reduction synthesis of silver−copper (Ag−Cu) bimetallic nanoparticles (BNPs) was achieved using NaBH 4 as a reducing agent and sodium dodecyl sulfate (SDS) as a stabilizer. Characterization and morphological evaluation indicates two distinctive UV/vis absorption peaks for Ag and Cu. XRD studies for nanocomposite showed crystallite size of 8.96014 nm having an FCC structure. SEM with EDX confirmed the particle sizes of BNPs and SDS to be 17.14 and 114.56 nm, respectively. Potential catalytic activity and kinetic parameters of Ag−Cu BNPs@SDS were monitored against Methylene Blue (MB), Methyl Orange (MO), and eosin-y (EY). The percentage degradation recorded for the nanocatalyst against MO, MB, and EY was 95.21%, 98.57%, and 96.65%, respectively. This method can be adopted for the removal of multiple dyes from industrial effluent on a larger scale.

This study is very promising for providing a renewable enrgy (H2 gas fuel) under the elctrochemical splitting of the wastwater (sewage water). This study has double benefits: hydrogen generation and contaminations removel. This study is carried out on sewage water, third stage treated, from Beni-Suef city, Egypt. Antimony tin oxide (ATO)/polyaniline (PANI)/PbI2 photoelectrode is prepared through the in situ oxidative polymerization of PANI on ATO, then PANI is used as an assistant for PbI2 deposition using the ionic adsorption deposition method. The chemical structural, morphological, electrical, and optical properties of the composite are confirmed using different analytical tools such as X-ray diffreaction (XRD), scanning electron microscope (SEM), transmision electron microscope (TEM), Fourier-transform infrared spectroscopy (FTIR), and UV-Vis spectroscopy. The prepared PbI2 inside the composite has a crystal size of 33 nm (according to the peak at 12.8°) through the XRD analyses device. SEM and TEM confirm the hexagonal PbI2 sheets embedded on the PANI nanopores surface. Moreover, the bandgap values are enhanced very much after the composite formation, in which the bandgap values for PANI and PANI/PbI2 are 3 and 2.51 eV, respectively. The application of ATO/PANI/PbI2 nanocomposite electrode for sewage splitting and H2 generation is carried out through a three-electrode cell. The measurements carreid out using the electrocehical worksattion under th Xenon lamp (100 mW.cm−2). The produced current density (Jph) is 0.095 mA.cm−2 at 100 mW.cm−2 light illumination. The photoelectrode has high reproducibility and stability, in which and the number of H2 moles is 6 µmole.h−1.cm−1. The photoelectrode response to different monochromatic light, in which the produced Jph decreases from 0.077 to 0.072 mA.cm−2 with decreasing of the wavelengths from 390 to 636 nm, respectively. These values confirms the high response of the ATO/PANI/PbI2 nanocomposite electrode for the light illuminaton and hydrogen genration under broad light region. The thermodynamic parameters: activation energy (Ea), enthalpy (ΔH*), and entropy (ΔS*) values are 7.33 kJ/mol, −4.7 kJ/mol, and 203.3 J/mol.K, respectively. The small values of ΔS* relted to the high sesnivity of the prepared elctrode for the water splitting and then the hydrogen gneration. Finally, a theoretical study was mentioned for calculation geometry, electrochemical, and thermochemistry properties of the polyaniline/PbI2 nanocomposite as compared with that for the polyaniline.

Bimetallic nanoparticles with synergistic effects revealed much higher catalytic activity than respective monometallic materials. This review describes bimetallic nanoparticles, especially silver nanoparticles, combined with the other transition elements, such as Ag−Fe, Ag−Co, Ag−Ni, and Ag−Cu, as an enhanced catalytically active material. The coverage is given to the various methods of preparation, in which factors responsible for different structures of bimetallic nanoparticles are thoroughly discussed. Lastly, we explore the use of bimetallic nanoparticles as a catalyst for the degradation of numerous organic pollutants that contribute to water pollution.
