“…For example, Wang's group reported a series of POM-based composite catalysts with nitrogen-deficient g-C 3 N x support for the degradation of ciprofloxacin (Figure 10). [125] These catalysts all exhibited high photocatalytic degradation efficiencies and very fast reaction rates. Especially, the g-C 3 N x /PTA-30 catalyst can remove 97.3% of ciprofloxacin in 5 minutes under visible light irradiation.…”

“…In a search on the Web of Science, about 850 articles about POM and degradation can be found, 650 for dyes, 202 for POM and pollutants, 135 for waste, 75 for industrial chemicals, and 70 for wastewater. A lower number of papers were found for POM and pesticides and antibiotics [28][29][30][31][32][33][34][35][36]. Herein, we describe examples of recent studies about POMs' ability for the degradation of mainly antibiotics, pesticides, and plastics.…”

“…POMs were described as a good choice for antibiotic degradation, thus reducing the pharmaceutical environmental impact. In fact, C 3 N 4 nanosheet composites loaded with POMs efficiently remove ciprofloxacin, tetracycline, as well as others pollutants, such as bisphenol A [28,29]. Polyoxotungstates (decatungstate, W 10 ) also showed the ability to decompose antibiotics, such as sulfasalazine (SSZ) and one of its human metabolites, sulfapyridine (SPD), with different specificities and rates [30].…”

Polyoxometalates (POMs) are clusters of units of oxoanions of transition metals, such as Mo, W, V and Nb, that can be formed upon acidification of neutral solutions. Once formed, some POMs have shown to persist in solution, even in the neutral and basic pH range. These inorganic clusters, amenable of a variety of structures, have been studied in environmental, chemical, and industrial fields, having applications in catalysis and macromolecular crystallography, as well as applications in biomedicine, such as cancer, bacterial and viral infections, among others. Herein, we connect recent POMs environmental applications in the decomposition of emergent pollutants with POMs’ biomedical activities and effects against cancer, bacteria, and viruses. With recent insights in POMs being pure, organic/inorganic hybrid materials, POM-based ionic liquid crystals and POM-ILs, and their applications in emergent pollutants degradation, including microplastics, are referred. It is perceived that the majority of the POMs studies against cancer, bacteria, and viruses were performed in the last ten years. POMs’ biological effects include apoptosis, cell cycle arrest, interference with the ions transport system, inhibition of mRNA synthesis, cell morphology changes, formation of reaction oxygen species, inhibition of virus binding to the host cell, and interaction with virus protein cages, among others. We additionally refer to POMs’ interactions with various proteins, including P-type ATPases, aquoporins, cinases, phosphatases, among others. Finally, POMs’ stability and speciation at physiological conditions are addressed.

“…However, HPA has certain solubility defects, a small surface area, and a low utilization rate for its active center. In general, insoluble polyoxometalates (POMs) are deposited with cations with a large radius, including K þ , Cs þ , and NH 4 þ ; similarly, HPAs are immobilized on appropriate carriers (Shi et al 2006;He et al 2020). Among the various POMs, HPAs with an appropriate Cs content have wide mesoporous surface areas because of the accumulation of primary particles.…”

The Cs3PW12O40/Ag3PO4 (CsPW/Ag3PO4) heterojunction photocatalyst in this study was prepared using a simple chemical precipitation method. Spherical CsPW particles were successfully deposited on Ag3PO4 nanocrystals, all the as-prepared samples are characterized by X-ray diffraction pattern (XRD), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR), UV visible spectroscopy (UV-Vis), and X-ray photoelectron spectroscopy (XPS). The catalyst activity in relation to rhodamine B (RhB) degradation was evaluated under visible light (λ > 420 nm). The CsPW/Ag3PO4 heterojunction photocatalyst can effectively degrade RhB. The Z-scheme 3% CsPW/Ag3PO4 heterojunction photocatalyst has a higher photocatalytic ability compared with the single-component photocatalyst CsPW or Ag3PO4. The comparatively high photocatalytic performance can be attributed to the high matching of the energy band position and close interface contact, suggesting an enhanced separation efficiency of the photoinduced carriers of the CsPW/Ag3PO4 heterojunction photocatalyst. The reactive species trapping experiments demonstrated photogenerated holes (h+) and superoxide radicals to be the main active components of photocatalytic degradation. A possible photocatalytic mechanism is subsequently proposed.
