Hydrogen-Induced Reconstruction of Molybdenum Dioxide on Carbon Supports Triggers Strong Metal-Support Interactions to Enhance Pt Catalyst Stability and Activity

Key Points

• The aim is to investigate how hydrogen-induced reconstruction of molybdenum dioxide can improve platinum catalyst stability and activity.
• Molybdenum dioxide was reconstructed under reducing conditions on carbon supports.
• Amorphous molybdenum oxide clusters decorated the carbon surface aiding in catalysis.
• Stability and activity assessments of the platinum catalyst were performed post-reconstruction.
• Enhanced stability of the platinum catalyst was observed, with increased performance under specified conditions.
• Metal-support interactions were significantly strengthened as a result of the reconstruction process.
• Activation energy for catalysis was reduced, indicating improved efficiency.
