Abstract
In this research, Orobanche aegyptiaca extract was utilized as an eco-friendly, and cost-effective green route for the construction of bimetallic silver-selenium nanoparticles (Ag-Se NPs). Bimetallic Ag-Se NPs were characterized by XRD, EDX, FTIR, HR-TEM, DLS, SEM/mapping and EDX studies. Antimicrobial, and antibiofilm potentials were tested against some selected pathogenic bacteria and unicellular fungi by ZOI, MIC, effect of UV exposure, and inhibition %. Reaction mechanism was assessed through membrane leakage assay and SEM imaging. HRTEM analysis confirmed the spherical nature and was ranged from 18.1 nm to 72.0 nm, and the avarage particle size is determined to be 30.58 nm. SEM imaging prove that bimetallic Ag-Se NPs presents as a bright particles, and both Ag and Se were distributed equally across O. aegyptiaca extract and Guar gum stabilizers. ZOI results showed that, bimetallic Ag-Se NPs have antimicrobial activity against S. aureus (20.0 nm), E. coli (18.5 nm), P. aeruginosa (12.6 nm), and C. albicans (18.2 nm). In addition, bimetallic Ag-Se NPs were able to inhibit the biofilm formation for S. aureus by 79.48%, for E. coli by 78.79%, for P. aeruginosa by 77.50%, and for C. albicans by 73.73%. Bimetallic Ag-Se NPs are an excellent disinfectant once it had excited by UV light. It was observed that the quantity of cellular protein discharged from S. aureus is directly proportional to the concentration of bimetallic Ag-Se NPs and found to be 244.21 μg/mL after the treatment with 1 mg/mL, which proves the antibacterial characteristics, and explains the creation of holes in the cell membrane of S. aureus producing in the oozing out of the proteins from the S. aureus cytoplasm. Based on the promising properties, they showed superior antimicrobial potential at low concentration (to avoid toxicity) and continued-phase durability, they may use in pharmaceutical and biomedical applications.

Abstract
![]()
This research discusses
the CO2 valorization via hydrogenation
over the non-noble metal clusters of Ni and Cu supported on graphitic
carbon nitride (g-C3N4). The Ni and Cu catalysts
were characterized by conventional techniques including XRD, AFM,
ATR, Raman imaging, and TPR and were tested via the hydrogenation
of CO2 at 1 bar. The transition-metal-based catalyst designed
with atom-economy principles presents stable activity and good conversions
for the studied processes. At 1 bar, the rise in operating temperature
during CO2 hydrogenation increases the CO2 conversion
and the selectivity for CO and decreases the selectivity for methanol
on Cu/CN catalysts. For the Ni/CN catalyst, the selectivity to light
hydrocarbons, such as CH4, also increased with rising temperature.
At 623 K, the conversion attained ca. 20%, with CH4 being
the primary product of the reaction (CH4 yield >80%).
Above
700 K, the Ni/CN activity increases, reaching almost equilibrium values,
although the Ni loading in Ni/CN is lower by more than 90% compared
to the reference NiREF catalyst. The presented data offer a better
understanding of the effect of the transition metals’ small
metal cluster and their coordination and stabilization within g-C3N4, contributing to the rational hybrid catalyst
design with a less-toxic impact on the environment and health. Bare
g-C3N4 is shown as a good support candidate
for atom-economy-designed catalysts for hydrogenation application.
In addition, cytotoxicity to the keratinocyte human HaCaT cell line
revealed that low concentrations of catalysts particles (to 6.25 μg
mL–1) did not cause degenerative changes.

Abstract
This review considers the features of the catalysts with different nanoparticle structures architecture transformation under the various pre-treatment types. Based on the results of the publications analysis, it can be concluded that the chemical or electrochemical activation of bimetallic catalysts has a significant effect on their composition, microstructure, and catalytic activity in the oxygen reduction reaction. The stage of electrochemical activation is recommended for use as a mandatory catalyst pre-treatment to obtain highly active de-alloyed materials. The literature is studied, which covers possible variants of the structural modification under the influence of thermal treatment under different processing conditions. Additionally, based on the literature data analysis, recommendations are given for the thermal treatment of catalysts alloyed with various d-metals.

Abstract
New highly active electrocatalysts were obtained by depositing bimetallic Pt-Cu nanoparticles on the surface of an N-doped carbon support. The structural–morphological characteristics and electrochemical behavior of the catalysts were studied. Using current stress testing protocols, their resistance to degradation was assessed in comparison with that of a commercial Pt/C material. A combined approach to catalyst synthesis that consists in alloying platinum with copper and doping the support makes it possible to obtain catalysts with a uniform distribution of bimetallic nanoparticles on the carbon surface. The obtained catalysts exhibit high activity and durability.
