In order to fully understand the progresses and development trends of global soil surface electrochemical research, in this paper, based on web of science core collection database and CiteSpace visual analysis software, soil surface electrochemistry literatures published from 1995 to 2019 were quantitatively analyzed from five aspects:the quantity and time characteristics of the subject, the spatial characteristics of cooperative research, the characteristics of co-occurrence network, the co-citation map and the development characteristics. The results showed that the United States, China and France ranked among the top three in the number of papers published, while the intermediary centrality showed that France, the United States and the United Kingdom were in the top three, and China was in the sixth place with an upward trend. The burst keyword detection based on citations indicated that the "cation exchange", "system" and "complexation" have been the research hotspots in recent ten years. The literature co-citation cluster analysis showed that biochar on soil improvement, the interaction between clay interlayer charge and Rhodamine 6G, surface potential change, colloid adsorption and desorption were the research focuses in the field; the improvement of soil by biochar and the interaction mechanism of charged particles in the double electric layer, and the hydrodynamic characteristics of soil clay mineral surface were the frontier issues in this field.
