Advanced electrocatalytic oxidation technology generally uses plate electrodes, because the hindered mass transfer has disadvantages of incomplete degradation, which limits the application of electrocatalytic degradation of pollutants. As a new type of electrode, porous carbon nanomembranes can effectively improve the mass transfer efficiency, thereby overcoming the shortcomings of traditional technology, it have been widely used in recent years. In this paper, the methods for preparing carbon films are reviewed, including electrospinning technology (EST), chemical vapor deposition (CVD) and template method, the principles and operating methods of the different techniques are introduced separately, and examples of the practical application of each method are given. Among them, electrospinning technology has the advantages of facilitating the modification of carbon films and the preparation of oriented carbon membranes. Secondly, the research on the electrocatalytic degradation of wastewater containing antibiotics, dye molecules and other organic compounds by carbon membrane is summarized, the universality of electrocatalysis is illustrated from the effective degradation results of carbon membranes for different organic compounds, the high efficiency, cleanliness and reproducibility of carbon membranes as electrodes for electrocatalytic degradation of wastewater are further demonstrated by different studies. These studies have further improved the performance of carbon membrane as electrodes by adding metals, metal oxides and metal-organic frameworks to the carbon membranes. Finally, the mechanism of electrochemical advanced oxidation, effect of electrode and main detection methods of free radicals are described, the mechanism of electrochemical advanced oxidation is introduced in terms of direct and indirect oxidation, and specific demonstration is made through equations, the possible electrode effects and their influence on electrocatalytic degradation of wastewater are cited as example. The methods of detecting free radicals are mainly introduced as quenching method and probe method, the principles and controversies are explained, and the development of carbon film electrocatalytic degradation of wastewater is prospected.
