“…processes involving eand h  must compete effectively with the major deactivation processes involving e --h  recombination. In the case of Ag3PO4, it is well known that this catalyst presents a negative surface, which means that it is well suited to attract h  and repel the electrons [60]. In addition, the electrons have lower effective masstherefore, they display a greater mobility with respect to h  [61,62].…”

In this work, for the first time, the instantaneous nucleation and growth processes of Ag nanoparticles on Ag3PO4 mediated by femtosecond laser pulses are reported and analyzed. The investigated samples are pure Ag3PO4 sample, electron‐irradiated Ag3PO4 sample, and laser‐irradiated sample. Complete characterization of the samples is performed using X‐ray diffraction (XRD), Rietveld refinements, field emission scanning electron microscopy, and energy dispersive spectroscopy (EDS). XRD confirms that the irradiated surface layer remains crystalline, and according to EDS analysis, the surface particles are composed primarily of Ag nanoparticles. This method not only offers a one‐step route to synthesize Ag nanoparticles using laser‐assisted irradiation with particle size control, but also reports a complex process involving the formation and subsequent growth of Ag nanoparticles through an unexpected additive‐free in situ fabrication process.

“…These optical transitions can be assigned to the interaction between Zn 4 O‐octahedra and organic linker as ligand . For Ag/Ag 3 PO 4 ‐IRMOF‐1 nanocomposite (Figure b) a wide absorption band from 400 to 500 nm was observed, which was attributed to the localized surface plasmon response (LSPR) of the Ag nanoparticles …”

MOF‐5 that sometimes called IRMOF‐1 has been intensively studied in recent years to develop efficient photocatalyst to degrade refractory organics and inactivate bacteria for wastewater treatment. In the present work, Ag/Ag3PO4 nanoparticles incorporated in IRMOF‐1 was successfully prepared via hydrothermal approach. The antibacterial activity of synthesized materials (IRMOF‐1, Ag/Ag3PO4 nanoparticles and Ag/Ag3PO4‐IRMOF‐1 nanocomposite was compared against two types of bacteria (Escherichia coli (E. coil) as Gram negative and Staphylococcus aureus (S. aureus) as Gram‐positive bacteria). The deactivation of the bacteria by the prepared material was measured in the dark and under visible light irradiation. The antibacterial activity of synthesized samples was investigated by determining the minimal inhibitory concentration (MIC), minimal bactericidal concentration (MBC), growth inhibition assay and inhibition zone. The Ag/Ag3PO4‐IRMOF‐1 nanocomposite exhibited stronger antibacterial activities than the Ag/Ag3PO4 nanoparticles and IRMOF‐1 at all tested bacteria types. Based on inhibition zone, without any light irradiation, Ag/Ag3PO4‐IRMOF‐1 nanocomposite showed activity toward E. coil, but in presence of light nanocomposite depicted activity toward S. aureus. The results demonstrated that antibacterial activity of all synthesized samples in the dark and light against S. aureus bacteria was more than E. coil bacteria. The antibacterial activity mechanism was due to sustained‐release of silver ions in the dark and reactive oxygen species (ROS) under visible light. The bioactivity of IRMOF‐1 was related to the degradation of the its structure and the release of Zn2+ ions into the culture medium that bind to the cell wall and deactivation bacteria.
