- Аннотация: The process was studied of spontaneous gas evolution (cavitation) at the interface with a Pd electrode saturated cathodically with hydrogen in 1 M NaOH and, then, immersed in one of the following liquids: distilled water (aged for more than 20 days after distillation), the same water after purging with argon, ethyl alcohol, ethyl alcohol after purging with argon, 1 M NaOH, and 3 M NaCl, as well as in the following technical fluids: glycerin (99%), glycerin (50% solution in water), ZIPPO gasoline, TC1 kerosene, and PMS-200 silicone oil brand used in diffusion vacuum pumps. Not only was the amount of gas released during cavitation in different liquids measured, but also the amount of remaining hydrogen in Pd. It is established that the intensity of cavitation is different in all cases. In aqueous solutions, alcohols, and silicone oil, intense “cold boiling” is observed, while the amount of hydrogen in Pd does not change. At the same time, cavitation gas is not released in gasoline and kerosene. In this case, the hydrogen content in Pd sharply decreases. It is likely that the process of hydrogenation of gasoline and kerosene proceeds at a higher rate than cavitation.
