  "abstract": "MXenes, 2D transition metal carbides, provide unique properties for a large range of applications including electrocatalysis and energy storage. Specifically, Ti 3 C 2 T x , has shown activity for the hydrogen evolution reaction (HER). MXenes are conductive, present a rich surface chemistry and do not contain rare and expensive elements. They are promising for next generation catalyst materials. Here, we study the HER activity of individual single-layer and multilayer Ti 3 C 2 T x flakes, using SECCM and ex situ AFM. Our results show that multilayer flakes have a much larger overpotential, revealing that the reaction proceeds more slowly in the interlayer volume compared to the open basal plane of a single layer. This opens avenues of optimization for MXene catalyst layer formulation that have not been considered before.",
