Caption

(a) SEM image of MoTe2 nanoflakes. (b) (Lower panel) Polarization curves of MoTe2 nanoflakes, bulk MoTe2 powders and graphene nanosheets alone and (upper panel) corresponding ring currents (dash line) and H2O2 percentage (solid line). (c) Derived mass activity of MoTe2 nanoflakes in comparison with those of Pt/Pd-Hg alloys and Au-based catalysts estimated from literature. (d) Polarization curves, ring currents and H2O2 percentage of MoTe2 nanoflakes at the initial state and after certain numbers of cycles during the accelerated durability test.
