Using high-efficient electrocatalysts is crucial for a fossil fuels-free future. Although many strategies have been proposed to boost the electrocatalysts’ performance, but the efficient and cost-effective methods are rare. Recently, hydrogen (H2) and oxygen (O2) production via water electrolysis is gaining growing trend. To efficient gas production using electrochemical water splitting (EWS), there are many resistances in electrolysis systems that must be reduced. One of the major resistances in the system that dramatically reduces the system\\\\\\\\\\\\\\\'s efficiency is the adhesion of evolved gas bubbles to the surface of electrode. Blocked active sites is occurred when bubbles adhere to the surface. As a result, decrease in mass transfer ability can be expected, which can severely damage gas production efficiency. One of the main techniques that able to reduce bubble adhesion is to make electrocatalysts with superaerophobic and/or superhydrophilic surfaces. These surfaces can be created using different morphologies such as nanosheets, nanotubes, nanowires, etc. In this review, in addition to getting acquainted with the mechanism of separation of bubbles from the surface and the application of superaerophobic/superhydrophilic surfaces as efficient electrocatalysts for hydrogen evolution reaction and other electrochemical reactions, the latest research in this field will be reviewed.
