“…Several transition metal chalcogenide are decorated by noble metals (Au, Ag, Pd, Pt) owing to their high activity and non-structural damage to the original species [9]. Within the category of noble metals, silver stands out as the most costeffective and highly conductive metal.…”

Cost-effective methods were employed in this study to synthesize core-shell nanoparticles of silver/Cr2O3 (SM) embedded with ultrathin MoS2 layers (SM1) to increase the properties and biocompatibility of the nanomaterials. For structural and morphological investigation, powder XRD, TEM, SEM, EDAX and XPS were used. Magnetic behaviour of SM and SM1 nanoparticles investigated by VSM was shown to be ferromagnetic, and when MoS2 nanosheets were injected, their magnetism decreased. The zeta potential of SM1 was also analyzed. This nanomaterial was synthesized to test the biocompatibility effectiveness of anticancer and antibacterial compounds. In MCF-7 adenocarcinoma (breast cancer) and HepG-2 hepatocellular carcinoma (liver cancer) cell lines, SM1 was investigated for antiproliferation effectiveness. The MCF-7 and HepG-2 cell lines both showed strong cytotoxic potential. Antimicrobial activity was observed against Staphylococcus aureus and Escherichia coli. This study provides strong evidence to support the development of cytotoxicity and antimicrobial properties for significant biomedical compatibility by demonstrating a key to understanding the Ag/Cr2O3 nanoparticle embedded in 2D MoS2 nanosheets on forming a unique interaction as well as the strategy for achieving in vitro efficiency.

Layered transition metal dichalcogenide (TMD) nanomaterials are promising alternatives to platinum (Pt) for the hydrogen evolution reaction (HER). However, the family of layered TMDs is mainly limited to Group IV–VII transition metals, while the synthesis of layered TMDs based on metals from other groups still remains a challenge. Herein, we demonstrate by atomic‐resolution transmission electron microscopy that hexagonal RuSe2 (h‐RuSe2) nanosheets with a mixture of 2H and 1T phases can be obtained by a facile bottom‐up colloidal synthetic approach. The obtained h‐RuSe2, which can be transformed into the thermodynamically favorable phase of cubic RuSe2 (c‐RuSe2) only after annealing at 600 °C, exhibits Pt‐like HER performance, with a fivefold turnover frequency enhancement compared to the c‐RuSe2 in alkaline media. Experimental results and density functional theory (DFT) calculations reveal that the enhanced adsorption free energies of H2O (ΔGnormalH2normalO* ), optimized adsorption free energies of H (ΔGH*), and increased conductivity of h‐RuSe2 contribute to its superior HER activity.

Experimental results and density functional theory (DFT) calculations reveal that the enhanced adsorption free energies of H 2 O (DG H 2 O *), optimized adsorption free energies of H (DG H*), and increased conductivity of h-RuSe 2 contribute to its superior HER activity.
