碩士 / 國立臺北科技大學 / 有機高分子研究所 / 103 / This thesis was mainly focused on the study of cathode and anode catalysts for water electrolysis, and it could be discussed in three sections. The first section focused on the preparation of the cathode catalyst. To overcome utilization and cost issues of platinum, graphene functionalized with Poly(diallyldimethylammonium chloride) (PDDA) was used as highly conductive supports to uniformly disperse platinum nanoparticles. PDDA which offered positive charge to graphene oxide was served as the stabilizer of Pt precursor when it was reduced by NaBH4 or N2H4. The best results were studied by using NaBH4 to reduce graphene oxide and Pt precursor, achieving 8.995 nm of Pt nanoparticles observed from TEM images and the hydrogen producing rate of 8.94 ml/min.
The second section focused on the preparation of the anode catalyst. Nanosized iridium oxide was prepared by hydrolysis method and following subsequent thermal treatment ranging from 200 to 500 °C to study the relationship among crystallinity and particle size and temperature. The best results were studied with IrO2 calcined in air at 500 °C, achieving a mean particle size of 4.7 nm observed from TEM images and the oxygen producing rate of 8.92 ml/min.
Finally, the properties of prepared cathode and anode catalysts were compared with commercial catalysts. Membrane Electrode Assembly (MEA) consisted of Pt/PDDA-graphene reduced by NaBH4 and IrO2 calcined at 500 °C had also been investigated by water electrolysis and decay test.
