This study shows a simplistic, efficient procedure to synthesize TiO-MoO-BMIMBr nanocomposites. Powder X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray spectroscopy, and X-ray photoelectron spectroscopy have all been used to completely analyse the materials. The detection of acetaminophen (AC) has been examined at a modified glassy carbon electrode with TiO-MoO-BMIMBr nanocomposites. Moreover, the electrochemical behavior of the nanocomposite modified electrode has been studied by cyclic voltammetry (CV), differential pulse voltammetry (DPV), chronoamperometry and electrochemical impedance spectroscopy (EIS). The linear response of AC was observed in the range 8.26-124.03 nM. The sensitivity and detection limits (S/N = 3) were found to be 1.16 μA L mol cm and 11.54 nM by CV and 24 μA L mol cm and 8.16 nM by DPV respectively.
本研究展示了一种简单、高效的合成TiO-MoO-BMIMBr纳米复合材料的方法。粉末X射线衍射、扫描电子显微镜、能量色散X射线光谱和X射线光电子能谱均已用于对材料进行全面分析。已在修饰有TiO-MoO-BMIMBr纳米复合材料的玻碳电极上研究了对乙酰氨基酚（AC）的检测。此外，通过循环伏安法（CV）、差分脉冲伏安法（DPV）、计时电流法和电化学阻抗谱（EIS）研究了纳米复合材料修饰电极的电化学行为。在8.26 - 124.03 nM范围内观察到AC的线性响应。通过CV法测得的灵敏度和检测限（S/N = 3）分别为1.16 μA L mol cm和11.54 nM，通过DPV法测得的分别为24 μA L mol cm和8.16 nM。
