The present work aims to study the photocatalytic and the anticorrosion properties of CeO₂-nanotubes (CeNTs) and CeNTs decorated by plasmonic nanoparticles (Au, Ag and Pt). CeNTs were obtained by a hydrothermal method, while the deposition precipitation using the urea method was chosen for the CeNTs metallization. The materials characteristics were performed using UV–Visible in Reflection Diffuse spectroscopy (RD/UV–Vis), Fourier transform infraRed spectroscopy, N₂ adsorption–desorption using BET method, X-ray diffraction and thermo-gravimetric (TG–DTA) analysis. The nanotubes anticorrosion properties on mild steel corrosion in 1 N HCl were estimated by means of the gravimetric method. The nanomaterials photocatalytic performance was evaluated in the methyl orange photodecomposition. The anticorrosion and the photodegradation efficiencies exceeded 98%.

目前的工作旨在研究CeO _2-纳米管（CeNTs）和由等离激元纳米粒子（Au，Ag和Pt）装饰的CeNTs的光催化和抗腐蚀性能。CeNTs是通过水热法获得的，而使用尿素法进行的沉积沉淀则选择用于CeNTs的金属化。使用紫外可见反射散射光谱（RD / UV-Vis），傅里叶变换红外光谱，N ₂进行材料特性分析使用BET方法进行吸附-解吸，X射线衍射和热重（TG-DTA）分析。通过重量法估算了纳米碳管在1 N HCl中对低碳钢腐蚀的防腐性能。在甲基橙光分解中评价了纳米材料的光催化性能。防腐和光降解效率超过98％。
