| Abstract Scope |
In this work, carbon modified TiO2 nanobelts (TiO2-C) were shown as an effective support for loaded palladium (Pd) nanoparticles (Pd/TiO2-C) in terms of improving the electrocatalytic capabilities and stability for methanol (MeOH) electrooxidation. It was discovered through cyclic voltammetry that the electrocatalytic performance of Pd/TiO2-C is 1.2 times that of Pd/AC and 3.5 times that of Pd/TiO2 in 1.0 M KOH + 1.0 M MeOH. These ratios correspond to the available electroactive surface area (EASA) of Pd. In addition, chronoamperometry revealed that the TiO2-C support is stable over 30 min at a potential of -0.3 V vs. SCE (saturated calomel electrode). Overall, this study shows the potential of conductive modification of TiO2 nanobelts for fuel cell and battery applications. |
