Gadolinium-Assisted Synthesis of Pt/C Electrocatalysts: WAXTS-DSE Insights into Active Area and ORR Activity

Key Points

• The aim is to explore how different gadolinium precursors affect the synthesis and performance of Pt-based electrocatalysts.
• Template-assisted synthesis used to create Pt-based catalysts with a porous structure.
• Systematic investigation of various gadolinium precursors on catalyst performance.
• Characterization of electrocatalysts using WAXTS-DSE techniques to assess active area.
• Gadolinium precursors significantly influence the structural properties of Pt/Gd catalysts.
• Enhanced ORR (oxygen reduction reaction) activity observed in catalysts with optimized porous structures.
• Identification of the active area correlates with improved electrochemical performance.
