摘要
The paper presents the experimental study's results on indirect sonication's effect on plasma formation and energy parameters in the cathodic regime of plasma-driven solution electrolysis (PDSE). In the study, two types of experiments were carried out. The first was to observe the effect of the indirect sonication on the transformation of the DC electrolysis of 10 wt% Na2CO3 aqueous solution from its Faradaic regime to the cathodic regime of PDSE with increasing the applied DC voltage. Sonication was found to decrease the average power needed to attain the plasma formation at the discharge electrode by ca. 10% compared to PDSE without sonication. The second experiment concerned the statistical determination of the energy parameters (current density and power consumption) in the cathodic regime of PDSE with varying the applied DC voltage. It was revealed that sonication reduces the applied DC voltage by 14 V to achieve the minimum current density at which sonication exhibits a synergetic effect on PDSE, reducing the power consumption by 21.5% compared to PDSE without sonication.
