The main issue is how to determine the stability of a sulfided edge in the absence of a well-defined sulfur chemical potential? &#8211; Indeed, in contrast to typical catalytic applications of MoS<sub>2<\/sub>, there is simply no sulfur reservoir under HER and, thus, each S that is released in the form of H<sub>2<\/sub>S is irreversibly lost. Our investigation concludes that the Mo-edge is likely to exchange its surface sulfur by surface OH*. These sites remain active for HER. The S-edge, on the other hand, is expected to be more stable, but once it starts loosing its S atoms, the HER activity will drop, leading to deactivation phenomena.<\/p>\n<a href=\"https:\/\/perso.ens-lyon.fr\/stephan.steinmann\/wp-content\/uploads\/2021\/07\/TOC_ex.pdf\" class=\"pdfemb-viewer\" style=\"\" data-width=\"max\" data-height=\"max\" data-toolbar=\"bottom\" data-toolbar-fixed=\"off\">TOC_ex<\/a>","protected":false},"excerpt":{"rendered":"<p>After some tedious work on a somewhat ill-defined problem, we are happy to announce the publication of our manuscript on the stability of 2H-MoS2 edges during the electrocatalytic hydrogen evolution reaction in acidic media in J.
