The adhesion of as‐formed gas bubbles on the electrode surface 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.
