The invention provides surfactant used for regulating the behaviors of gas on an electrode surface, and belongs to the technical field of electrochemical efficiency regulation. One or more surfactants is/are added to regulate the behaviors and the state of the gas on the electrode surface in order to effectively reduce and even eliminate the adhesion of gas on the electrode surface and improve the adhesion behavior of the gas on the electrode surface. The disadvantages of complex preparation process, high price and unsuitableness for large-scale use of methods for regulating the behaviors of the electrode surface through changing the electrode structure and controlling the chemical composition of the electrode surface are overcome, and a new idea is provided for the control of the behaviors of the gas on the electrode surface.
