| 研究実績の概要 |
Currently, iron oxalate dihydrate (abbreviated as FOD-ore) was synthesized from iron ore using a process involving oxalic acid for iron extraction, followed by photo-reduction. Various analytical techniques were employed to characterize the physicochemical properties of the FOD-ore sample. The FOD-ore was tested for its ability to catalyze the degradation of rhodamine B (RhB), a representative organic pollutant found in wastewater. The results revealed that the FOD-ore could degrade over 85% of RhB faster than that achieved with FOD alone. Additionally, the remaining calcium oxalate was used as a calcium source to produce Fe-doped hydroxyapatite as a photocatalyst. The obtained Fe-doped hydroxyapatite was characterized by several methods and will be used for photocatalytic H2 evolution.

理由
This research project is advancing according to our strategy, which involves extracting calcium oxalate from slag and utilizing it as a calcium source to fabricate photocatalysts. Furthermore, we have employed these newly obtained photocatalysts to initiate the degradation of organic pollutants, marking the initial phase of assessing their photocatalytic effectiveness.

| 今後の研究の推進方策 |
Our next step involves creating a composite material by combining Fe-doped hydroxyapatite derived from slag with C3N4, which will then be utilized for testing its photocatalytic efficiency in hydrogen (H2) evolution. This experimentation aims to assess the performance of the synthesized samples in catalyzing the generation of hydrogen through photocatalysis. Additionally, we will explore various conditions and parameters during the composite fabrication process and H2 evolution testing to identify optimal conditions for maximizing the performance of the resulting sample.
