• Polyoxometalates and their derivatives: structural tuning of versatile electrocatalysts for water splitting (2026) · Energy Materials · doi

  This review systematically summarizes the core significance of state-of-the-art progress in POMs and their derivatives for EWS, with emphasis on their structural modulation strategies and the intrinsic relationship between their architectures and bifunctional electrocatalytic activity for water splitting. We comprehensively discuss the synthetic methods for POM composites with various supporting materials, including carbides, metallic compounds, and MOFs, as well as cutting-edge advances in structural construction and rational design of microscale active sites for POM derivatives. Meanwhile, the catalytic pathways and mechanisms of the HER and OER are also discussed in detail. Nevertheless, despite encouraging progress achieved to date, numerous critical challenges remain to be addressed for POM-based catalytic materials. For instance, pristine POMs inherently suffer from low intrinsic electrical conductivity, facile dissolution and leaching in electrolytes, and insufficient long-term stability under harsh Wang et al.
