Abstract

A cerium compound with asymmetric amidinate ligands [Ce(ⁱPrNC(Me)N^tBu)₃] has been reported and characterized in this paper. The compound showed good volatility and thermal stability, which were evaluated by TGA (thermogravimetric analysis). Corresponding results indicated the great potential of this compound for the chemical vapor deposition (CVD) process. Therefore, CeO_x film and particle (loaded on TiO₂) deposition were conducted by CVD using Ce(ⁱPrNC(Me)N^tBu)₃ and O₂ as precursors. Meanwhile, the photocatalytic activity of the CVD CeO_x–TiO₂ composite was evaluated by degrading methylene blue solution under the irradiation of ultraviolet light (365 nm).

酰胺基铈化合物及其作为CeO x基材料的CVD前体的应用

摘要

本文报道了具有不对称^a酰胺配体[Ce（ⁱ PrNC（Me）N ^t Bu）₃ ]的铈化合物。该化合物显示出良好的挥发性和热稳定性，通过TGA（热重分析）对其进行了评估。相应的结果表明该化合物在化学气相沉积（CVD）工艺中具有巨大潜力。因此，的CeO _X膜和颗粒（加载在TiO ₂）沉积通过CVD使用铈进行（^我PRNC（ME）N^吨丁基）₃和O ₂作为前体。同时，CVD CeO _x –TiO ₂的光催化活性 通过在紫外线（365 nm）照射下降解亚甲基蓝溶液来评估复合材料。
