abstract = "This work highlights a simple and efficient approach for the development of
PtZn catalyst materials with tunable content of Zn. Nanoparticles of PtZn
deposited on high surface area carbon Vulcan XC-72R material were
synthesized by microwave-assisted polyol method, giving control over the size
and dispersion of nanoparticles. Cyclic voltammetry and electrooxidation of
adsorbed CO were used to investigate the electrochemical behavior of
synthesized catalysts: PtZn/C (90:10); PtZn/C (85:15) and PtZn/C (75:25). It
was found that PtZn/C catalysts have high electrocatalytic performance in
methanol oxidation reactions. In comparison to the corresponding catalyst with
the different Zn loading, it was concluded that PtZn (90:10)/C catalyst had
better activity compared to PtZn/C (85:15) and PtZn/C (75:25) catalysts. The
observed high catalytic activity in the methanol oxidation reaction of
synthesized catalysts can be ascribed to the very efficient microwave synthesis
and well-balanced content of Zn as alloying metal., Ovaj rad predstavlja jednostavan i efikasan pristup za razvoj PtZn katalizatora sa različitim sadržajem Zn. Nanočestice PtZn istaložene na ugljeničnom materijalu Vulcan XC-72R velike površine, sintetisane su poliol metodom pomoću mikrotalasne pećnice, dajući kontrolu nad veličinom i disperzijom nanočestica. Za ispitivanje elektrohemijskog ponašanja sintetisanih katalizatora PtZn/C (90:10); PtZn/C (85:15) i PtZn/C (75:25) korišćeni su ciklična voltametrija i elektrooksidacija adsorbovanog CO. Utvrđeno je da PtZn/C katalizatori imaju visoke elektrokatalitičke performanse u reakcijama oksidacije metanola. Poređenjem katalizatora sa različitim sadržajem Zn, zaključeno je da PtZn/C (90:10) katalizator ima bolju aktivnost u odnosu na PtZn (85:15) i PtZn (75:25) katalizatore. Uočena visoka katalitička aktivnost sintetisanih katalizatora u reakciji oksidacije metanola može se pripisati veoma efikasnoj mikrotalasnoj sintezi i dobro izbalansiranom dodavanju Zn kao legirajućeg metala sa različitim sadržajem u PtZn/C katalizatorima.",
