Polyoxometalate (POM)-based binary and ternary hybrids, including combinations of POMs, semiconductors, nanostructured carbon (carbon nanotubes, graphene, carbon dots, etc.), and metal nanoparticles (MNPs), are key materials in photoelectrocatalysis. POM plays a key role in the construction of nanohybrids and contributes to their photoelectrochemical catalytic properties. These composites combine the properties of two or three functional nanoscale materials, resulting in a wide range of applications, including catalysis, energy conversion and storage, molecular sensors, and electronics. Herein, we summarize the latest progress in POM-based binary nanohybrids (POM/metal, POM/semiconductor, and POM/nanocarbon) and ternary nanohybrids (metal/POM/nanocarbon), particularly in energy materials for photocatalysis, fuel cells, biosensors, and photoelectrochemical devices. Current applications are critically assessed, and promising target systems are discussed.

“…These compounds exhibit an impressive open nanocluster structure, multi‐electron redox properties, and stability in their cluster structure throughout reduction‐oxidation processes. These characteristics make them highly promising for a range of applications in various catalytic reactions [36–37] and electrocatalysis, [38–39] and other electrochemical reactions [40–58] . In 2018, Dong, Cronin, and their co‐workers developed a dual‐function Lewis acid and base catalyst for Li−S batteries in the form of an Ag(I)‐substituted Keggin K 3 [H 3 AgIPW 11 O 39 ] cluster.…”

Lithium‐sulfur (Li−S) batteries emerge as compelling contenders for next‐generation energy‐storage devices, boasting a noteworthy mass‐specific energy of 2600 Wh kg−1. However, the cycle stability and commercialization of Li−S batteries encounter challenges because of polysulfide shuttle and uncontrolled lithium dendrite growth. In this study, we present a polyoxometalates‐based dual‐function [PMo12O40]3− cluster@carbon nanotube modified polypropylene (PP) separator (PMo12@CNT/PP) to regulate polysulfide transformation and safeguard the lithium anode in Li−S batteries. Leveraging its multi‐electron redox properties and stable cluster structure, the PMo12 cluster acts as a polysulfide mediator, effectively capturing and promoting electrochemical polysulfide transformation. The incorporation of CNT fosters consistent Li‐ion nucleation, stabilizes the lithium anode, and impedes dendrite formation throughout cycling. Hence, Li−S cells equipped with the PMo12@CNT/PP separator display higher capacity and better stability (675 mAh g−1 at 3.0 C and 0.02 % capacity decay per cycle over 700 cycles). The pouch cells with a sulfur loading 4.5 mg cm−2 exhibit an initial discharge specific capacity of 925 mAh g−1 at 0.1 C, and remain 849 mAh g−1 after 40 cycles, underscoring the significant potential for practical applications of Li−S batteries.

Photocatalytic water splitting is capable of converting abundant solar energy into environmentally friendly and renewable chemical energy, presenting a promising solution to alleviate the energy crisis and combat environmental pollution. The development of high‐performance photocatalysts is crucial for significantly improving the efficiency of the hydrogen evolution reaction (HER) involved. Polyoxometalate (POM)‐derived materials, known for their tunable compositions, diverse structures, electron storage/release capabilities, as well as quasi‐semiconductor photochemical properties, serve as highly efficient catalysts in sustainable photosynthesis. This comprehensive review navigates the latest advancements in the assembly strategies and HER performance of POM‐based crystalline materials. It also discusses the composite materials formed by infiltrating POM into metal‐organic frameworks (MOF) and examines the roles of transition metal compounds derived from polyoxometalates, such as sulfides and carbides, in photocatalytic HER. Emphasis is placed on the prospects for the future development of POM‐based compounds as photocatalysts, along with several strategies and outlooks that could facilitate their progress. POM‐derived materials are believed to have significant potential to enhance hydrogen production efficiency while maintaining thermal stability in HER processes.
