Abstract
- In this work, ZnFe2O4 nanoparticles were synthesized by hydrothermal method while the hummer method was used to synthesize GO nanosheet. GO/ZnFe2O4 nanocomposites (GO/ZFO) were prepared by mixing of GO with ZnFe2O4 in mass ratio of 1:99, respectively. The structure, morphology, and physical – chemical characteristics were determined by Raman spectroscopy, Transform Electron Microscopy (TEM), and Fourier Transform Infrared Spectroscopy (FT-IR). The CO gas adsorption properties of GO/ZFO were investigated in the range of 25 – 200 ppm at room temperature using quartz crystal microbalance (QCM). GO/ZFO nanocomposites show great adsorption – desorption capacity, high repeatability, and the largest adsorption performance of 1.21‰ (0.098 µg.cm-2 at 200 ppm). The results show that this new approach is promising of spinel structure materials for CO adsorption at room temperature.
