Polyoxometalates have emerged as promising bactericidal agents. In the current study, the bactericidal activity of polyoxometalate K[PMoO] against () O157:H7 and its possible underlying mechanisms were explored. The obtained results demonstrated that K[PMoO] could effectively kill O157:H7 at millimolar levels. Moreover, K[PMoO] treatment also induced significant increases in recA protein expression and further triggered characteristic apoptosis-like bacterial death events such as DNA fragmentation and phosphatidylserine exposure. In conclusion, polyoxometalate K[PMoO] possesses a desirable antibacterial activity, and induction of bacterial apoptosis-like death might be involved in its underlying bactericidal mechanisms.

Photochromic films have attracted increasing attention for their potential in information storage and photoswitchable devices. Developing novel photochromic materials is still a highly challenging topic. In this work, we successfully obtained an unprecedented mixed-heteroatom-templated Er-incorporated polyoxometalate [HN(CH)]NaKH{Er(HO)WO[SeTeWO][B-α-TeWO]}·117HO () by concurrently introducing the [TeO] and [SeO] heteroanion templates into the Er/WO system.

Polyoxometalates (POMs) have good potential for applications in different fields, including conducting materials, optics, and electrocatalysis. Of particular significance is the synthesis and development of addendum POMs. Molybdenum-oxo clusters, which are renowned for their diverse structures and electronic properties, were utilized to facilitate the synthesis of innovative materials.

The spin coherence phenomena of a system consisting of a mononuclear 3d transition metal = 1/2 centre embedded in a polyoxometalate with low nuclear-spin abundance, [(-CH)N]H[SiWOCuZn], have been revealed for the first time. Variable-temperature Hahn-echo experiments using the pulsed electron spin resonance technique showed that its coherence lifetime remains at the submicrosecond level even above 100 K.

Reducing toxic metal concentrations to extremely low levels has long posed a challenge. Polyoxometalate supported ionic liquids (POM-SILs) offer significant potential for advanced water remediation, but their application is limited by complex preparation, toxic solvents, and poor stability due to leaching, compromising sustainability. We introduced a sustainable approach for selectively removing Pb(II) in complex electroplating wastewater using charged POM-SILs composite, synthesized by directly grafting lacunary Keggin ions ([α-SiWO], SiW) onto charged ammoniated polystyrene via a straightforward, solvent-free process.
