MoSe2 WSe2 alloys showed improved catalytic activity toward hydrogen evolution in acid and base

What is it about?

In this paper we demonstrated a colloidal synthesis for producing Mo1-xWxSe2 alloys with nanoflower morphology, thus exhibiting control over both morphology and composition simultaneously. The alloys showed higher catalytic activity in both acid and base with lower overpotentials and improved charge transfer kinetics. In addition, we tested the influence of the synthetic process on the catalytic activity of nanoflowers of MoSe2 and found that the specifics of the synthetic procedure affect the catalytic activity. We concluded that the atomic fine structure and stoichiometry of the products play a crucial role in the catalytic activity.
