Abstract:
This research focuses on the effect of temperature for Pt/C electrocatalyst preparation on hydrogen evolution reaction (HER). Pt/C electrocatalyst is synthesized using a polyol method in ethylene glycol with 1 M ascorbic acid as a mild reducing agent. The investigated parameter is temperature (which will vary from room temperature to 100 Celsius degrees). From the cyclic voltammetry (CV), the results showed that Pt/C catalyst synthesized by polyol method at room temperature and 60 Celsius degrees cannot promote hydrogen desorption peak when compared to other catalysts. The Pt/C catalyst synthesized at 100 Celsius degrees gave the highest electrochemical surface area (ESA) at around 43.45 m2/gPt. From the linear sweep voltammetry (LSV), the activities of the electrocatalyst were tested in an acid solution. The Pt/C synthesized at 100 Celsius degrees had highest activities for HER. The exchange current density, Tafel slope and overpotential at 10 mA/cm2 were around 5.208 mA/cm2, -59.3 mV/dec and -0.277 VSCE, respectively. From the value of Tafel slope: -59.3 mV/dec, it could be indicated that mechanism of 20 percent Pt/C synthesized at 100 Celsius degrees catalyst occurs through Heyrovsky mechanism
