FIELD: chemistry.
SUBSTANCE: method of producing hydrogen-saturated metal nanoparticles includes laser ablation of a solid metal target placed in a proton-conducting liquid. During ablation, negative bias is applied on the target relative to the anode immersed in the working liquid. The apparatus for producing said nanoparticles includes an ablation chamber with a plug and an input optical window for laser radiation, a solid metal target placed in a liquid which fills the ablation chamber. Outside the ablation chamber there is a laser with an optical system which focuses laser radiation through an optical window on the target. Outside the ablation chamber, the apparatus is provided with a direct current source and an anode immersed in the working liquid, the anode being made of chemically neutral conducting material, and a cathode made of high-electroconductivity material. The cathode is electrically connected to the target.
EFFECT: invention enables to obtain hydrogen-saturated nanoparticles of aluminium, titanium, palladium, gold and iron, increases the rate of producing said nanoparticles, reduces power consumption and simplifies the process and the equipment.
