Electrocatalytic activity. a Linear sweep voltammograms comparing the activity of m-WS2–Au stock and purified samples to a m-WS2 reference dispersion not reacted with AuCl3 towards the HER. The inset presents the linear region of the data used to determine the Tafel slope and exchange current density. b Thickness normalized exchange current density of these electrode materials plotted as a function of the mean nanosheet length making up the network electrode. This plot enables comparison to other TMD-based nanomaterial networks catalysts presented in the literature
