Novel heterostructure shows 4 times higher mass activity for hydrogen evolution, indicating superior stability.
We report a novel heterostructure of ultrafine Pt nanocrystals on amorphous MoO3, showing 4 times higher mass activity than commercial Pt/C for hydrogen evolution and superior stability with a negligible decay in overpotential after 10 000 cycles.
