The α-Fe₂O₃/TiO₂ nanostructure material, synthesized on FTO (fluorine-doped tin oxide) substrate using the hydrothermal method at 180 °C for 5 h, exhibits an enhanced performance in the photocatalytic degradation of an organic dye. The optical band gap was found to decrease compared to the TiO₂ one. The photocatalytic performances of the as-prepared heterojunction were evaluated with the degradation of methylene blue (MB) in an aqueous medium. The results revealed that the photocatalytic activity of the Fe₂O₃/TiO₂/FTO was much higher than that of the pure TiO₂. In addition, the photocurrent of the Fe₂O₃/TiO₂/FTO heterojunction was remarkably higher than that of the bare TiO₂ electrode. The obtained results indicate that the heterojunction formed between Fe₂O₃ and TiO₂significantly improved the separation efficiency of the photo-generated electron–hole pairs. The electrochemical properties of the as-synthesized nanocomposite materials (α-Fe₂O₃/TiO₂) were also evaluated with cyclic voltammetry for 1000 cycles. This nanocomposite exhibited an enhanced specific discharge capacity compared to the Fe₂O₃ nanomaterial. The as-produced material proved to have an impressive performance as a high-capacity anode for Na⁺-ion batteries.

所述的α-Fe ₂ ö ₃ /二氧化钛₂纳米结构材料，采用水热法，在180上FTO（氟掺杂的氧化锡）衬底合成℃下保持5小时，表现出的有机染料的光催化降解的增强的性能。发现与TiO ₂相比，光学带隙减小。制备的异质结的光催化性能通过在水介质中降解亚甲基蓝（MB）进行评估。结果表明，Fe ₂ O ₃ / TiO ₂ / FTO的光催化活性远高于纯TiO ₂。另外，Fe ₂ O的光电流₃ / TiO ₂ / FTO异质结明显高于裸露的TiO ₂电极。所得结果表明，Fe ₂ O ₃和TiO ₂之间形成的异质结显着提高了光生电子-空穴对的分离效率。所合成的纳米复合物材料的电化学性能（的α-Fe ₂ ö ₃ /二氧化钛₂）也与循环伏安法评价1000个循环。与Fe ₂ O ₃相比，该纳米复合材料表现出增强的比放电容量纳米材料。事实证明，这种制成的材料作为Na ⁺离子电池的高容量阳极具有令人印象深刻的性能。
