Revealing the platinum single-atom anchoring mechanism through sequential surface engineering in Mo 2 TiC 2 T x MXene

Key Points

• This research aims to identify the anchoring mechanism of platinum single atoms on Mo2TiC2Tx MXene through surface engineering techniques.
• Utilized a tunable electroreduction strategy for surface engineering of Mo2TiC2Tx MXene.
• Identified Mo atomic vacancies as anchoring sites for platinum single atoms.
• Confirmed that Mo atomic vacancies serve as primary sites for the effective anchoring of platinum single atoms.
• Established that vacancy-directed MXene functionalization enhances single-atom catalysis.
