synthesis and electrochemical study of ptir nanomaterials
abstract
nanomaterials have a number of unique chemical and physical properties and have
attracted tremendous attention due to their potential for applications in a variety of areas
including fuel cell and biosensor development. the focus of this work was the design of novel
platinum iridium electrocatalysts with high electrocatalytic activity towards the key
electrochemical processes in direct methanol fuel cells (dmfc) and glucose sensors.
n anoporous ptlr electrodes with different ratios of pt to ir were prepared on ti and
carbon nanotube (cnt) substrates using a one-step facile hydrothermal method. the
nanostructure and morphology of the fabricated electrocatalysts were characterized using
scanning electron microscopy (sem), energy dispersive x-ray spectrometry (eds), x-ray
diffraction (xrd) and x-ray photoelectron spectroscopy (xps). electrochemical analyses were
performed using cyclic voltammetry (cv), chronoamperometry (ca), linear voltammetry (lv)
and electrochemical impedance spectroscopy (eis).
