Abstract
In this investigation, a spin-coated titanium oxide (TiOx, 60 nm thick with a porous morphology and mostly in anatase structure) modified platinum (Pt) catalyst was fabricated atop of a silicon (Si) substrate before annealing for the use as an efficient anodic catalyst for the methanol electro-oxidation (MO). The temperature of annealing was optimized; seeking the highest catalytic activity and stability toward the MO. The PtTi-700 catalyst (that was annealed at 700 °C) showed the highest activity (with ca. 11-fold increase in the oxidation current density) and stability (ca. 19-fold increase after 50 cycles of potential scanning between −0.6 and 0.4 V vs. Ag/AgCl) if compared to the bare (unmodified) Pt electrode. The enhancement in the charge transfer kinetics and significant reduction of the catalyst’s poisoning could elaborate the origin of catalysis.
