Hydride (H–) species on oxides have been extensively studied over the past few decades because of their critical role in various catalytic processes. Their syntheses require high temperatures and presence hydrogen, which involves complex equipment, energy costs, strict safety protocols. tend to decompose atmospheric oxygen water, reduces activities. These challenges highlight need for further research improve stability efficiency processes develop safer cost-effective synthesis methods. This paper introduces an ultrasonic fabrication method gallium hydride liquid metal (LM) nanoparticles (Ga–H@LM NPs) water describes evaluation properties. The Ga–H@LM NPs were synthesized by dispersing metals eutectic gallium–indium using a two-step ultrasonication process ice bath. Ga–H was confirmed Fourier-transform infrared spectroscopy. demonstrated rapid hydrogenation 4-nitrophenol reductive degradation azo dyes within minutes without external reducing agents like NaBH4. proposed mechanism high-energy cavitation at interface between LM promotes formation H2 from its activation form particles surface during ultrasonication. study has significant implications advancing field catalysis it provides novel efficient stable oxides.

Liquid gallium exhibits a unique, geometrically structured surface that directly influences the diffusion and coalescence of metal solutes at its surface. The complex interplay between different chemical species gallium's unusual interfacial properties remains poorly understood, yet it plays crucial role in controlling dopant dynamics, with applications spanning catalysis, nanoscale fabrication, flexible electronics, liquid batteries. Herein, large‐scale simulations ab initio ‐trained machine learning force fields reveal strikingly interactions Ag, Au, Bi, Li, Pt, Sn interfaces, including both liquid‐vacuum liquid‐gallium oxide boundaries. For example, Bi dopants migrate strongly toward vacuum interfaces but are repelled by interface, while Au is interfaces. results have direct implications for involving doped systems, optimizing patterning plasmonic catalytic or use Li More broadly, these findings underscore critical modulating offering new pathways tuning functionalities technologies.
