In recent years, the piezophotocatalytic mechanism had been intensively recognized as a potential and promising route to sewage treatment. Here we report the piezoelectric effect improved heterogeneous photocatalysis of g-C₃N₄/Ag/ZnO (g-CN/A/Z) tricomponent in rhodomine B (RhB) degradation. Initially, the nanomaterials were characterized for their physico-chemical and optoelectronic properties using analytical techniques such as x-ray diffraction (XRD), scanning & transmission electron microscopes (SEM & TEM), UV–vis spectrophotometer and photoluminescence spectroscopy (PL). In addition, the photoelectrochemical activity of determining the photocurrent density and electrochemical impendence response were also been conducted. The catalytic properties of the tricomponent, g-CN/A/Z was studied with the degradation of RhB with visible photons irradiation and ultrasonication. In piezophotocatalysis, degradation up to 89% of RhB was achieved with 1.26 folds synergetic effect on par to the photocatalysis and piezocatalysis.

近年来，压电光催化机理被广泛认为是一种潜在的、有前景的污水处理途径。在这里，我们报告了 gC ₃ N ₄的压电效应改进的多相光催化/Ag/ZnO (g-CN/A/Z) 三组分降解罗多明 B (RhB)。最初，使用分析技术如 X 射线衍射 (XRD)、扫描和透射电子显微镜 (SEM & TEM)、紫外-可见分光光度计和光致发光光谱 (PL) 对纳米材料的物理化学和光电特性进行了表征。此外，还进行了测定光电流密度和电化学阻抗响应的光电化学活性。研究了三组分 g-CN/A/Z 的催化性能，通过可见光子照射和超声处理降解 RhB。在压电光催化中，RhB 的降解率高达 89%，与光催化和压电催化相比，协同效应提高了 1.26 倍。
