In this study, particles of titanium dioxide (TiO₂) were modified with particles of zinc oxide (ZnO) using a pulsed plasma chemical method, with ZnO initially being obtained by an electrospark method. The particle size of the synthesized TiO₂ powder modified with ZnO nanoparticles ranged from 30 to 100 nm. The morphology of the nanoparticles was found to be diverse, mainly represented by spheres, ovals, and parallelograms. The phase composition was a mixture of crystalline phases characteristic of TiO₂ (rutile and anatase) and ZnO, with the predominant phase being anatase. The presence of Zn–O–Ti bond is typical for all samples of TiO₂ powder modified with ZnO nanoparticles prepared using a pulsed plasma chemical synthesis, which indicates the formation of a solid solution. The optical and photocatalytic properties of the modified nanoparticles were also studied, as well as the band gap was determined. For some samples, a narrowing of the band gap was recorded. The samples showed high photocatalytic activity in the decomposition of methylene blue under the influence of ultraviolet and visible light in the wavelength range of 400–630 nm. Methylene blue degradation efficiency was 66% in visible light spectrum.

在这项研究中，使用脉冲等离子体化学方法用氧化锌 (ZnO)粒子对二氧化钛 (TiO ₂ ) 粒子进行改性，其中 ZnO 最初是通过电火花法获得的。用ZnO纳米颗粒改性的合成TiO ₂粉末的粒径范围为30至100 nm。发现纳米颗粒的形态多种多样，主要以球形、椭圆形和平行四边形为代表。相组成是 TiO ₂（金红石和锐钛矿）和 ZnO的结晶相特征的混合物，主要相是锐钛矿。Zn-O-Ti 键的存在是所有 TiO ₂样品的典型特征用脉冲等离子体化学合成制备的 ZnO 纳米颗粒改性的粉末，这表明形成了固溶体。还研究了改性纳米粒子的光学和光催化性能，并确定了带隙。对于一些样品，记录到带隙变窄。在波长范围为 400-630 nm 的紫外线和可见光的影响下，样品对亚甲蓝的分解表现出很高的光催化活性。在可见光光谱中，亚甲蓝降解效率为 66%。
