Summary Polyoxometalates could be viewed as the molecular counterpart of the metal oxides, which are essential ingredients for various energy conversion and storage applications. In this manuscript, we review the progress of engineering functional polyoxometalates toward energy applications, focusing on, but not limited to, polyoxotitanate, polyoxotungstate, and polyoxomolybdate. These polyoxometalates are considered to be promising candidates for dye‐sensitized solar cell, perovskite solar cell, lithium‐ion battery, lithium‐sulfur battery, supercapacitor, and water‐splitting system. We believe advanced energy devices with better performance could be derived from further engineering the polyoxometalates owing to their molecular design flexibility.

Laburpena: Polioxometalatoak (POMak) kimika ez-organikoaren munduan ezagunak diren metalez eta oxigenoz osatutako kluster anionikoak dira. Azaldu ohi duten forma, konposizio eta propietate aniztasunaren ondorioz, POMek aplikazio ugari dituzte teknologiari, ekonomiari edo ingurugiroari lotutako arlo ezberdinetan. Nahiz eta aspaldidanik aplikazio katalitikoetan erabili, gaur egun etorkizunerako garrantzitsuak izango diren esparru oso ezberdinetarako ikertzen ari dira, besteak beste, hondakin-uren tratamenduan, medikuntzan, konputazio kuantikoan, energia-iturri berriztagarrietan edota sentsore kimiko lumineszenteetan. Horrengatik guztiagatik, polioxometalatoen kimika, etorkizun handiko kimika ezorganikoaren alorreko esparru dinamikoenetariko bat dela baiezta genezake.Hitz gakoak: polioxometalatoak, materialen zientzia, katalisia, nanozientzia, sentsore lumineszenteak, medikuntza.Abstract: Polyoxometalates (POMs) are a well known class of anionic metal-oxygen clusters within the area of inorganic chemistry, with a large variety of shapes, compositions and structures. These features make POMs unique compounds with a wide range of applications in current fields of interest related to technology, economy and environment. In spite of their traditional use as catalysts, they are nowadays being explored for very different issues such as wastewater treatment, medicine, quantum computing, renewable energies or luminescent sensors. Therefore, POM chemistry can be considered as one of the most dynamic fields of the inorganic chemistry, as well as one of the fields with the greatest future.

“…Compared to these “traditional” stimuli, the CO 2 stimulation can overcome the disadvantages, and its stimulation strength can easily be tuned through a continuous gas flow . A number of CO 2 ‐switchable surfactants, CO 2 ‐tunable vesicles, CO 2 wormlike micelles, CO 2 ‐responsive microgels, gas sensor, and CO 2 ‐responsive membranes have been reported . Moreover, the CO 2 gas can also be used as a trigger to induce the gelation .…”

Gelation of Triblock Copolymers in Aqueous Solution through CO₂ -Triggered Electrostatic Interaction

Polymer systems displaying CO2‐triggered rheology alteration are widely investigated in recent years, which can change from nonviscous liquid to high‐viscosity solution or even gel by passing CO2 through. Among those polymer systems, a previous study of the group shows that a rationally designed ABA‐type triblock copolymer with a hydrophilic middle block and two CO2‐responsive end blocks can undergo either gel–sol or sol–gel transition triggered by CO2 as a result of increase or decrease in lower critical solution temperature of A blocks, respectively. This paper describes a new and more flexible approach to achieving CO2‐induced gelation of polymer aqueous solution at much lower polymer concentrations. It consists in mixing two water‐soluble ABA triblock copolymers that have the same B block but different A blocks: for one polymer, the A blocks are a negatively charged polyelectrolyte, and for the other polymer, the A blocks can be turned positively charged under CO2 stimulation. In this way, CO2 bubbling through an aqueous solution of the two constituent triblock copolymers can induce complexation of the oppositely charged A blocks and, as a result, gelation of the solution of mixed triblock copolymers.
