Abstract
<p><span style="font-size:12pt"><span style="font-family:"Times New Roman",serif"><span style="font-size:10.0pt">Over the past few years, there has been a growing awareness of how industrial wastewater is endangering aquatic life and our access to clean water. As a result, research in the development of new catalysts and technology for treating wastewater has gained much attention. Our group has developed a single-component metal borate photo-Fenton catalyst that exhibited a 5-fold increase in catalytic activity compared to Fe<sub>3</sub>O<sub>4</sub> nanoparticles. In this study, different iron precursors were investigated in the synthesis of C, N-doped FeBO<sub>3</sub> to achieve a higher yield and a higher photo-Fenton activity. The C, N-doped FeBO<sub>3</sub> prepared using 13 wt% of Fe<sub>2</sub>(SO<sub>4</sub>)<sub>3</sub> as precursor yielded 585 mg of product compared to 80 mg, using Fe<sub>3</sub>O<sub>4</sub> nanoparticles as the Fe precursor. Additionally, the as-prepared C, N-doped FeBO<sub>3</sub> using Fe<sub>2</sub>(SO<sub>4</sub>)<sub>3</sub> as precursor showed the highest photo-Fenton degradation efficiency of various organic pollutants compared to other Fe sources.</span></span></span></p>
