Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201304759-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>The adhesion of as‐formed gas bubbles on the electrode surface</bold> usually impedes mass‐transfer kinetics and subsequently decreases electrolysis efficiency. Here it is demonstrated that nanostructured MoS₂ films on conductive substrates show a faster hydrogen evolution reaction (HER), current increase, and a more‐stable working state than their flat counterpart by significantly alleviating the adhesion of as‐formed gas bubbles on the electrode. This study clearly reveals the importance of a nano‐porous structure for HER, which should be general and beneficial for constructing other gas‐evolution electrodes. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg5nnfnd00" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
