Penumuhan Nanopartikel Logam dengan Metode Kimia Basah untuk Meningkatkan Prestasi Super kapasitor Elektro kimia
Abstract: Metals nanoparticles
(platinum-PtNs and palladium-PdNs) have successfully beengrown on the surface
of carbon electrodes and stainless steel current collectors. Thegrowths of PtNs
and PdNs have been carried out using Wet Chemical Method.Characterizations of
the PTNs and PdNs have been performed by using FESEM(Field Emission Scanning
Electron Microscopy) and XRD (X-Ray Diffraction) formorphological and structural
studies. Meanwhile, in order to test the performance ofsupercapacitor cells,
Impedance Electrochemical Spectroscopy (EIS) has beendone. The experiment
results confirmed that PtNs and PdNs grew uniformly on thesurface of carbon
electrodes and stainless steel. The XRD pattern confirmed that thePtNs grown on
the substrates were represented by two XRD peaks at 2θ = 40.247oand 46.815o
with their crystallographic planes of (111) and (200). Meanwhile, twopeaks at
2θ = 40.225° and 2θ = 46.713° represented PdNs grown on the substrates.EIS
measurements resulted the spesific capacitances of supercapacitor cells of
8.81and 20.2 F/gr for the carbon electrodes with and without PtNs,
respectively. Thegrown of PdNs on the cells resulted in improving of the
spesific capacitances ofsupercapacitor cells from 8.81 F/gr to 10.22 F/gr.
