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.
