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.

Eutectic gallium-indium (EGaIn), a room-temperature liquid metal, has garnered significant attention for its applications in soft electronics, multifunctional materials, energy engineering and drug delivery. A key factor influencing these diverse is the spontaneous formation of native passivating oxide shell that not only encapsulates metal but also alters properties from bulk counterpart. Using environmental scanning transmission electron microscopy, we report
