Abstract
Simulirano je elektrokemijsko ponašanje kobalta u 1 M otopini NaOH u području razvijanja vodika. Simulacija struja - potencijal odgovora provedena je korištenjem računalnog programa SigmaPlot. Za vrijednosti nagiba katodnog Tafelovog pravca od -115 mV dec -1 i gustoće struje izmjene od 5,6 × 10 -6 A cm -2 modeliran je odziv kobalta pri linearnoj polarizacije te prikazan u obliku odgovarajućih grafova. Simulacija impedancijskog odziva kobalta u istom elektrolitu provedena je korištenjem računalnog programa ZView. Elektrokemijski impedancijski spektri modelirani su primjenom jednostavnog Randlesovog električnog ekvivalentnog kruga i prikazani u Nyquistovom i Bodeovom prikazu. Iz rezultata elektrokemijske impedancijske spektroskopije određeni su hrapavost elektrode, gustoća struje izmjene i nagib katodnog Tafelovog pravca.
Abstract (english)
Simulation of the electrocatalytic activity of cobalt for hydrogen evolution reaction was performed in 1 M NaOH solution. The simulation of current – potential correlation was performed using the SigmaPlot program. For Tafel slope of -115 mV dec -1 and exchange current density of 5.6×10 -6 A cm -2 , a linear polarization response for cobalt was modelled. Simulation of cobalt impedance spectra in 1 M NaOH solution was also performed, using the ZView program. Electrochemical impedance spectra were modelled using Randles simple electrical equivalent circuit and presented in form of Nyquist and Bode plot. From these experimental data, electrode surface roughness, exchange current density and Tafel slope were derived.
