In this study, the physical properties of ZnO were facile controlled by the synthesis method with the addition of capping and precipitation agents. As-prepared ZnO samples had different morphologies such as carnation flower-like ZnO (CF-ZnO), rose-flower-like ZnO (RF-ZnO), rod-like ZnO (R-ZnO), and nanoparticle ZnO (N-ZnO) and were characterized by SEM, XRD, N₂ adsorption/desorption isotherms, FT-IR, and DR/UV-vis. All samples had a crystallite structure of hexagonal wurtzite type. The CF-ZnO and RF-ZnO samples had the hierarchical structure like a carnation flower and a beautiful rose, respectively. R-ZnO was composed of many hexagonal rods and few spherical particles, while N-ZnO microstructures were made up of nanoparticles with approximately 20–30 nm, exhibiting the largest surface area, pore volume, and pore width among as-prepared samples, and their crystal size and bandgap energy were 17.8 nm and 3.207 eV, respectively. The catalytic performances of ZnO samples were evaluated by degradation of Tartrazine (TA) and Caffeine (CAF) under low UV irradiation (15 W). N-ZnO showed a high photocatalytic activity compared to other samples. Besides, the reaction kinetics was investigated by the first-order kinetic model, and the catalytic performance of ZnO was evaluated through several organic pollutants.

氧化锌物理性质的简便控制及其在增强光催化中的应用

在这项研究中，可以通过添加封端剂和沉淀剂的合成方法轻松控制ZnO的物理性质。制备的ZnO样品具有不同的形态，例如康乃馨花状ZnO（CF-ZnO），玫瑰花状ZnO（RF-ZnO），棒状ZnO（R-ZnO）和纳米颗粒ZnO（N-ZnO ）并用SEM，XRD，N ₂表征吸附/解吸等温线，FT-IR和DR / UV-vis。所有样品均具有六方纤锌矿型的微晶结构。CF-ZnO和RF-ZnO样品的层次结构分别为康乃馨花和美丽的玫瑰花。R-ZnO由许多六角形棒和少量球形颗粒组成，而N-ZnO的微结构由约20–30 nm的纳米颗粒组成，在制备的样品中具有最大的表面积，孔体积和孔宽度，并且它们的晶体尺寸和带隙能量分别为17.8 nm和3.207 eV。ZnO样品的催化性能通过在低紫外线（15 W）下降解酒石酸（TA）和咖啡因（CAF）进行评估。与其他样品相比，N-ZnO显示出高的光催化活性。除了，
