| Description | Journal: Materials Research Express Magnetite $(Fe_{3}O_{4}$) and hematite $(α-Fe_{2}O_{3}$) iron oxide nanoparticles were synthesized using the co-precipitation method via subsequent heat treatment using ferrous chloride $(FeCl_{2}.4H_{2}$O) as a source of iron. The synthesized powder was annealed at high temperature in an air atmosphere to promote the formation of the hematite $(α-Fe_{2}O_{3}$) phase. Both oxide phases of iron oxide were characterized using x-ray diffraction, thermogravimetric, and differential scanning calorimetric analysis, and Raman spectroscopy. The phases of as-synthesized nanoparticles were confirmed by XRD and Raman studies. The thermal behavior and weight loss of the initial powdered $Fe_{3}O_{4}$ to $α-Fe_{2}O_{3}$ was studied using TG-DSC analysis. In the present case, the $Fe_{3}O_{4}$ and $α-Fe_{2}O_{3}$ nanoparticles were used for the electrochemical sensing of acetaminophen $(C_{6}H_{9}NO_{2}$). The sensing of acetaminophen was performed by $Fe_{3}O_{4}$ and $α-Fe_{2}O_{3}$ modified glassy carbon electrode, using a potential controlled cyclic voltammetric technique. The $Fe_{3}O_{4}$ and $α-Fe_{2}O_{3}$ nanoparticles exhibited electrocatalytic ability for sensing acetaminophen. Detailed results are included. |
