MnO2 and CuBi2O4 hybrid microstructures for efficient nonenzymatic hydroxylamine detection
In this report, CuBi2O4 and CuBi2O4/MnO2 are synthesized using coprecipitation and hydrothermal methods, respectively. CuBi2O4/MnO2 has been extensively used for the electrochemical detection of hydroxylamine. CuBi2O4 and CuBi2O4/MnO2 are well characterized by XRD, XPS, and FESEM to reveal the structural and morphological features of the material. Electrochemical measurements like CV, chronoamperometry, and impedance are studied to reveal the electrochemical behavior of CuBi2O4/MnO2 towards hydroxylamine. Stability, reproducibility, and interference studies are performed to reveal the suitability of CuBi2O4/MnO2 as an electrode material for the electrochemical detection of hydroxylamine.
Graphical abstract
CuBi2O4 and CuBi2O4/MnO2 are synthesized using coprecipitation and hydrothermal methods, respectively, and tested for the electrochemical detection of hydroxylamine. CuBi2O4/MnO2 exhibited a high sensitivity of 488 μA mM−1 cm−2 with a limit of detection 0.86 μM, revealing its ability to display good electrochemical activity towards hydroxylamine.
期刊介绍：
Journal of Chemical Sciences is a monthly journal published by the Indian Academy of Sciences. It formed part of the original Proceedings of the Indian Academy of Sciences – Part A, started by the Nobel Laureate Prof C V Raman in 1934, that was split in 1978 into three separate journals. It was renamed as Journal of Chemical Sciences in 2004. The journal publishes original research articles and rapid communications, covering all areas of chemical sciences. A significant feature of the journal is its special issues, brought out from time to time, devoted to conference symposia/proceedings in frontier areas of the subject, held not only in India but also in other countries.
