Sunlight-driven photocatalytic and anticancer properties of biogenic synthesized gold nanoparticles (AuNPs) employing Polygala elongata

Journal of King Saud University - Science, Год журнала: 2024, Номер 36(5), С. 103158 - 103158

Опубликована: Март 7, 2024

The current study uses an economical and ecologically friendly method to produce gold (Au) nanoparticles (NPs) using Polygala elongata leaf (PEL) extract as a reducing stabilizing agent. synthesized materials were characterized range of methods, including BET analysis, TEM-SAED, FT-IR, UV–Vis, XRD. Biogenic AuNPs' spherical form was shown by SEM TEM investigations, which also showed that the particles' size 10–20 nm, their distribution homogeneous, there observed minimal aggregation. production biogenic AuNPs confirmed observation surface plasmon resonance peak in absorption spectra, detected at 540 nm. Additionally, studies conducted on catalytic, cytotoxic, antioxidant, anticancer characteristics AuNPs. exhibited adaptable applications heterogeneous catalyst, achieving percentage degradations 73 % 88 under UV light irradiation, particularly catalyzing reduction Methylene Blue (MeB). Furthermore, antioxidant properties evaluated DPPH free radical scavenging assay regarding rutin, widely used antioxidant. With cytotoxicity value 500 µg/ml, produced had strong dose-dependent inhibitory effect development lung cancer cell line (A549). Therefore, hold potential across various research domains, spanning biological industrial sectors, well removal harmful contaminants water purification.

Photocatalytic N2 conversion to NH3 is a green, sustainable pathway with renewable energy sources and carbon neutrality. In this research, ternary TiO2 QDs/TiO2 OVs/Cu5FeS4 nanocomposites were prepared by an easy affordable procedure utilized produce clean ammonia without sacrificial agent. The amount of produced green the optimum nanocomposite achieved was 17,274 μmol L–1 g–1, which approximately 20.9, 6.48, 4.45, 2.26, 1.45 times higher than those commercial TiO2, QDs, OVs, Cu5FeS4, OVs photocatalysts, respectively. Lattice compatibility through developed homojunction within integration Cu5FeS4 nanoparticles led establishment double S-scheme homo/heterojunction system, improved photocatalytic activity maintaining electrons holes high oxidation reduction power greatly reduced recombination charges, acceleration charge transfer migration. Besides, promoted surface area compared pure components, introducing oxygen vacancies, reducing particle size boosted NH3. results research are basis for rational design homojunction/heterojunction visible-light-responsive systems nitrogen fixation reactions.

Recent Advances in Vanadate-Based Materials for Photocatalytic Hydrogen Production

Molecules, Год журнала: 2025, Номер 30(4), С. 789 - 789

Опубликована: Фев. 8, 2025

Metal vanadates are a developing group of semiconducting metal oxide materials that gaining increasing attention due to their great redox potential, effective separation photogenerated electron–hole pairs, and tunability structural physicochemical properties. Their rational design as photocatalysts can find use in various applications, including energy conversion/storage environmental remediation. In particular, one the viable ways address energy-related issues be through sustainable production hydrogen (H2), clean fuel produced by photocatalysis using vanadates. However, rapid recombination pairs limits practical photocatalysts, thus, many efforts have been devoted optimizing enhance efficiency. Herein, we provide comprehensive review deals with recent development strategies (Ni, Fe, Zn, Ag, In, Bi, rare earth, etc.) working mechanisms. synthesis, doping, cocatalyst loading, heterojunction creation, carbon loading also reviewed for photocatalytic H2 production. The challenges vanadate-based facing discussed along significant potential environmentally friendly
