The Use of a Novel Three-Electrode Impulse Underwater Discharge for the Synthesis of W-Mo Mixed Oxide Nanocomposites

The novel three-electrode underwater pulse discharge excited by two independent high-voltage sources was used for the synthesis of W-Mo mixed oxide nanoparticles for the first time. The spectral and optical characteristics of the discharge were studied. It was found that the composition of the formed mixed oxides particles can be controlled by the discharge current between the anodes-general cathode pair. The chemical composition and morphology of obtained particles were studied by using X-ray diffraction spectroscopy and electron microscopy. The dynamic light scattering was used to measure the average particle diameter and zeta-potential. The photocatalytic performance of mixed oxides nanoparticles was estimated through the degradation of Rhodamine B under visible light irradiation conditions. It was found that the composition of the nanoparticles affects the photocatalytic properties.

Automated summary

The study utilized a novel three-electrode underwater pulse discharge to synthesize W-Mo mixed oxide nanoparticles, demonstrating that the composition of the particles can be controlled by adjusting the discharge current. Characterization techniques such as X-ray diffraction spectroscopy and electron microscopy were used to analyze the chemical composition and morphology of the particles, while the photocatalytic performance was evaluated through the degradation of Rhodamine B under visible light irradiation conditions.
