| 要約: | AC doped Ti02 nanoparticles were synthesis via ultrasonic assisted sol-gel method
which are utilized as supercapacitor materials. The electrochemical properties of
the AC/TiO2 nanoparticles were investigate using Cyclic Voltammetry (CV)
analysis. The crystal structure of the composite has been characterized by X-ray
diffraction analysis (XRD) and Fourier transform infrared spectroscopy (FTIR).
The electrochemical measurements reveal that the specific capacitance of 267.910
and 226.190 Fg-1 have been obtained for 20% Ti02 loading at 50 and 100 mVs-1
respectively with good capacity retention, as it maintained 90% of its original
capacitance after 100th subsequent cycles. The XRD pattern confirmed the purity of
ACrri02 nanoparticles and the crystallite sizes of AC/TiO2 in composites were
smaller than the undoped samples. The FTIR analysis reveal that the presence of
carbonyl group of AC/TiO2 nanoparticles is advantageous to fast faradaic reactions
resulted good capacitance. Therefore, results demonstrated that the AC/TiO2
nanoparticles is a promising electrode material for supercapacitor application. |
