The electrocatalytic oxidation of small organic molecules, such as methanol,
ethanol and formic acid has been extensively studied due to their properties that make
them suitable for use in fuel cells. Particularly, the electrochemical oxidation of
formic acid has been comprehensively examined as the anodic reaction in direct
formic acid fuel cell. The main goal in the development of the catalysts for formic
acid oxidation (FAO) is to find the optimal balance between catalytic performance
(activity/stability) and the catalyst cost, i.e. quantity of the noble metal used.
In the work presented herein, we explored the synergistic effects of the
supporting material and annealing temperature on the performance of Pt thin film
catalysts for FAO in acidic media. Our results show that compared to the as-prepared
Pt films, the annealed (500 oC) films show exceptional activity for FAO reaction on
both Pt/Ni and Pt/Cr catalysts, with 5-fold and 15-fold improvement, respectively.
The 50...0 oC annealed Pt/Cr catalyst was found to be the most active, the most
selective and the most stable catalyst in our study. A catalyst with the best marks for
all three characteristics is a very rare find in electrocatalysis in general.
