Pt and Pt x Sn y catalysts with different atomic ratios (90:10, 80:20, 70:30, 60:40 and 50:50) supported on carbon support (Vulcan XC-72) were prepared using the modified polyol method. The composition, particle size and structure of these catalysts were characterized by energy dispersive x-ray spectroscopy (EDX) and x-ray diffraction (XRD). XRD data revealed that the estimated particle sizes of all synthesized catalysts were approximately 2.0-3.0 nm. Cyclic voltammetric data showed that Pt 80 Sn 20 exhibited the highest catalytic activity toward ethanol oxidation compared to other ratios in terms of area-normalized current densities. Chronoamperometry (CA) data confirmed that Pt 70 Sn 30 was the most stable among the prepared catalysts with long-term poisoning rate of 4.25 × 10 -3 (% s −1 ), which was four times lower than Pt (1.70 × 10 −2 ). The catalyst with the optimum performance was used as the ink pigment of the inkjet ink formulations.

“…Likewise, the rate of poisoning of the tin-containing catalysts was much lower by one magnitude as compared to the Pt catalysts. This can be explained that in the Sn enriched catalysts, the tin oxides can supply oxygenated species to oxidize the CO adsorbates [28][29][30].…”
