Abstract

The low natural abundance and high material cost of Pt restrict the practical implementation of electrochemical hydrogen production. Enormous efforts have recently been dedicated to fabricate various nanostructured dichalcogenides to exposure more edge sites for amplifying HER catalysis. On the other hand, this often results in the less stability and the inefficient electrical conductivity of the dispersed nanostructured 2D catalysts. As an alternative approach, lattice strains have been suggested to be an effective way to enhance the catalytic activity of 2H sulfide compounds, although the underlying mechanisms have not been fully understood. Since annular bright-field (ABF) STEM is capable of imaging both the heavy element of molybdenum and the light element of sulfur, it was employed to image the distribution of Mo and S atoms in the monolayer crystal.
