Article Synopsis
- - Surface morphology plays a crucial role in the effectiveness of electrocatalysts, and manipulating atomic-level structures can enhance their performance.
- - The study focused on how heat treatment in a specific reductive atmosphere at 300 °C influences the arrangement of surface atoms in platinum thin-film catalysts, improving their catalytic properties.
- - Results showed that increasing the proportion of (100) planes through thermal annealing can boost catalyst performance for methanol oxidation reactions significantly, highlighting a method for designing better electrocatalysts.
The development of electrocatalytic materials of enhanced activity and efficiency through careful manipulation, at the atomic scale, of the catalyst surface structure has long been a goal of electrochemists. To accomplish this ambitious objective, it would be necessary both to obtain a thorough understanding of the relationship between the atomic-level surface structure and the catalytic properties and to develop techniques to synthesize and stabilize desired active sites. In this contribution, we present a combined experimental and theoretical study in which we demonstrate how this approach can be used to develop novel, platinum-based electrocatalysts for the CO electrooxidation reaction in CO(g)-saturated solution; the catalysts show activities superior to any pure-metal catalysts previously known.
