Argon plasma reduced Pt nanocatalysts supported on carbon nanotube for aqueous phase benzyl alcohol oxidation

- Low temperature plasma reduction effectively enhances Pt dispersion on CNT.
- These Pt nanoparticles on CNT are remarkably active in benzyl alcohol oxidation.
- The catalytic property of Pt remains the same compared to hydrogen reduced Pt.
- The Pt nanoparticles could be the same by two reduction methods.
- Or the passivation of Pt surface occurs when exposing to air.
