Carbon supported platinum catalysts for ethanol electrooxidation were synthesized by modified polyol synthesis method, assisted by microwave or reflux heating. Synthesized catalysts were characterized by XRD, STM and TGA techniques to determine their structural and morphological properties. STM and XRD investigations revealed small particle size (~3nm), while TGA showed Pt loading of 20% in both samples. Electrocatalytic activity of prepared catalysts was examined by potentiodynamic measurements and compared to commercial Pt catalyst (Pt/C-Tanaka). The highest activity for ethanol electrooxidation was observed with Pt catalyst prepared by microwave irradiation. The increase in activity can be assigned to the benefits of microwave assisted synthesis, such as small particle size and homogeneous particle distribution on the support.
Platinski katalizatori na ugljeničnoj podlozi su sintetizovani korišćenjem modifikovanog poliol postupka uz primenu mikrotalasnog ili refluks zagrevanja za reakciju elektrooksidacije etanola. Dobijeni katalizatori su karakterisani strukturno i morfološki korišćenjem XRD, STM i TGA tehnika. STM i XRD ispitivanja su pokazala malu veličinu čestica (~3nm), dok je TGA pokazala da je sadržaj metala u katalizatoru 20%. Elektrokatalitička aktivnost sintetizovanih katalizatora je ispitivana potenciodinamičkim merenjima i upoređena sa komercijalnim platinskim katalizatorom (Pt/C-Tanaka). Najbolju aktivnost za elektrooksidaciju etanola pokazao je platinski katalizator sintetizovan uz korišćenje mikrotalasnog zagrevanja. Veća aktivnost se može pripisati prednostima mikrotalasnog zagrevanja u toku sinteze jer je dobijen katalizator sa malom veličinom i homogenom di stribucijom čestica.
