The RGO-supported HoVO-ZnO nanocomposite was synthesized using the ultra sonication process. X-ray diffraction patterns, Field emission scanning electron microscopy, high resolution transmission electron microscopy, Diffractive Reflectance spectroscopy, and photoluminescence spectroscopy were employed to examine the heterostructured photocatalyst in this research study. The photocatalytic efficiency of the RGO-supported HoVO-ZnO nanoparticles, under UV light irradiation, in the degradation of Rhodamine-B dye was investigated. Undoped ZnO, bare HoVO4, and HoVO -ZnO, degraded at 55.6, 57.5, and 74.33 percent in 45 min, respectively. This new RGO coupled HoVO-ZnO exhibits enhanced photocatalytic efficiency compared to the bare ZnO and HoVO-ZnO nanocomposite.
采用超声法制备了 RGO 支撑的 HoVO-ZnO 纳米复合材料。本研究采用 X 射线衍射图谱、场发射扫描电子显微镜、高分辨率透射电子显微镜、漫反射反射光谱和光致发光光谱对异质结构光催化剂进行了研究。在紫外光照射下，研究了 RGO 负载的 HoVO-ZnO 纳米粒子对罗丹明 B 染料的光催化降解效率。未掺杂 ZnO、纯 HoVO4 和 HoVO-ZnO 在 45 分钟内分别降解了 55.6%、57.5%和 74.33%。与纯 ZnO 和 HoVO-ZnO 纳米复合材料相比，这种新的 RGO 耦合 HoVO-ZnO 表现出更高的光催化效率。
