A new lab study shows that platinum single atoms on crumpled Mo2TiC2Tx MXene achieve overpotentials as low as 24.9 mV at 10 mA cm−2 and a mass activity of 11 859 mA mgPt−1 for alkaline hydrogen evolution, according to PubMed.
A new experimental study demonstrates that a strain-engineered platinum single-atom catalyst supported on crumpled Mo2TiC2Tx MXene nanosheets delivers remarkably low overpotentials in alkaline hydrogen evolution, according to the indexed abstract on PubMed. The work pairs atom-level platinum dispersion with deliberate mechanical deformation of the support. The result: unusually low overpotentials and high mass activity under laboratory testing conditions.
- Overpotential of 24.9 mV at 10 mA cm−2 and 75.5 mV at 50 mA cm−2, the indexed abstract reports.
- Pt mass activity of 11 859 mA mgPt−1, approximately 178-fold higher than commercial Pt/C, according to PubMed.
- Tafel slope of 31.61 mV…
