Recent advances in polyoxometalate-based materials and their derivatives for electrocatalysis and energy storage

Abstract

This review highlights the significant roles of POMs in electrocatalysis and energy storage, and summarizes the recent advances of POM-based materials and their derivatives in water-splitting, the CO2RR, the NRR, SCs, and rechargeable batteries.

Bioinspired polyoxometalates as light-driven water oxidation catalysts

“…Materials derived from Keggin and Wells-Dawson-type POMs have been used as multifunctional catalytic systems due to their high Brønsted acidity (Li et al, 2007;García-López et al, 2019;Mürtz et al, 2024). In general, polyoxometalate-based materials, and especially those incorporating redox-active transition metal ions, possess an enormous potential as water oxidation catalysts due to the following features (Bonchio et al, 2006;Proust et al, 2012;Zhang et al, 2024): (i) high stability toward oxidative degradation without altering their parent structure, (ii) remarkable redox properties, (iii) behavior as robust molecular ligands, (iv) abundant nature of their components, (v) structural availability to bind water molecules, and (vi) photocatalytic activity.…”

A Co and Fe bimetallic MOF with enhanced electrocatalytic oxygen evolution performance: exploring the electronic environment modifications upon Fe incorporation

“…However, these non-conventional energy sources have their own limitations due to their geographical confinement and uneven distribution/accessibility all year round. 1,2 Among energy carriers, hydrogen is the most preferred one due to its clean and non-toxic nature, high calorific value, and relatively easy storage. 3 Electro/photocatalytic water splitting produces H 2 in a clean way.…”

Surfactant-assisted morphology modification of nanostructured MnMoO4 for high-performance asymmetric supercapacitors

“…This causes major issues including climate change, environmental pollution and the continuous depletion of fossil fuels. 1,2 Therefore, an emergent environmentally sustainable plan is required to overcome the disputes over conventional energy sources. 3,4 Hence, developing energy from diverse sustainable and renewable energy sources such as solar, wind and geothermal energy and finding an effective approach to store this energy is critical in the current scenario.…”
