In order to achieve widespread application of fuel cell technology, the
development of an efficient and economical catalyst is a crucial step. Reducing the
diameter of catalyst particles, producing particles with a specific orientation surface,
and alloying noble metals with less expensive metals are possible approaches to
improve catalyst performance. This study will be focused on novel ways for creating
PtSnZn catalysts that are more effective for the anodic reactions in fuel cell such are
methanol, ethanol and formic acid oxidation reactions. PtZn and PtSnZn
nanoparticles were produced using the microwave assisted polyol method and were
supported on high surface area carbon Vulcan XC-72R material. The electrochemical
behavior of synthesized catalysts was investigated utilizing the cyclic voltammetry,
chronoamperometric technique, and electro-oxidation of adsorbed CO. To determine
the catalyst's physicochemical characteristics, X-ray diffraction (XRD), transmission
electr...on microscopy analysis (TEM), and thermogravimetric analysis (TGA) were
used. High catalytic activity of the PtSnZn/C catalysts was achieved thanks to the
benefits of microwave synthesis and carefully adjusted metal alloying.
