Virtual and Physical Prototyping, Journal Year: 2025, Volume and Issue: 20(1)

Published: Feb. 6, 2025

Extreme low-temperature environments, such as those in aerospace, polar expeditions, and deep-sea exploration, demand efficient energy storage systems. Conventional technologies face major limitations under these conditions, including electrolyte freezing, restricted interfacial reaction kinetics, microstructural instability. In contrast, 3D printing offers transformative solutions with precise control, multifunctional material integration, optimisation, effectively addressing challenges related to compatibility structural complexity. However, the mechanisms for optimising performance remain poorly understood, of processes materials needs further exploration. Moreover, comprehensive integration materials, processes, device designs remains an ongoing challenge. This review systematically summarises key their characteristics storage, exploring potential pathways through which enhances performance. Particular emphasis is placed on its unique applications design, engineering, multi-material coupling. Unlike studies focused single or technologies, this adopts interdisciplinary systematic framework, linking properties optimisation. It provides critical theoretical guidance practical insights advancing scientific understanding engineering extreme technologies.

Electron Shuttling of Iron‐Oxygen‐Cobalt Bridging in Cobalt Assembled Iron Oxyhydroxide Catalyst Boosts the Urea Oxidation Stability and Activity

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: March 21, 2025

Abstract Iron (Fe)‐based materials hold great potential as urea oxidation reaction (UOR) catalysts, however, the deactivation of active Fe‐oxyhydroxide (FeOOH) species induced by its dissolution during catalytic process under high current densities is still significant challenge. Herein, cobalt (Co) assembled FeOOH constructed, and formation Iron‐Oxygen‐Cobalt (Fe‐O‐Co) bridging triggers electron transfer from Co to Fe sites. This shuttling induces low valence state sites in FeOOH. Co‐FeOOH catalyst achieves a density 1000 mA cm −2 at voltage merely 1.59 V, showing substantial improvement compared pure (1.97 V). Meanwhile, urea‐assisted anion exchange membrane electrolyzer, after 24 h continuous operation , fluctuation 12.4%, significantly lower than that (49.9%). The situ experiments theoretical calculations demonstrate Fe‐O‐Co endows suppressive Fe‐segregation, fast charge Fe(Co)OOH phase negative‐shifted d‐band center metal sites, boosting UOR stability activity.
