Supported fluorine-doped alpha-Fe2O3 nanomaterials were synthesized by Plasma Enhanced-Chemical Vapor Deposition (PE-CVD) at temperatures between 300 and 500 degrees C, using a fluorinated iron(II) diketonate-diamine compound as a single-source precursor for both Fe and F. The system structure, morphology and composition were thoroughly investigated by various characterization techniques, highlighting the possibility of controlling the fluorine doping level by varying the sole growth temperature. Photocatalytic H2 production from water/ethanol solutions under simulated solar irradiation evidenced promising gas evolution rates, candidating the present PE-CVD approach as a valuable strategy to fabricate highly active supported materials.
通过等离子体增强化学气相沉积（PE-CVD）在300至500摄氏度之间合成了负载型氟掺杂α-Fe2O3纳米材料，使用二酮铁（II）-二胺氟化物化合物作为铁和氟的单源前驱体。通过各种表征技术对体系结构、形态和组成进行了深入研究，突出了通过改变唯一的生长温度来控制氟掺杂水平的可能性。在模拟太阳辐射下，水/乙醇溶液的光催化产氢显示出有前景的气体析出速率，表明当前的PE-CVD方法是制备高活性负载材料的一种有价值的策略。
