Abstract

Wastewater pollution is a worldwide concern, and wastewater treatment is gaining growing global attention. Electro-Fenton is a promising method for the treatment of wastewater containing organic pollutants. This work offers an overview and bibliometric analysis of research on electro-Fenton treatment of wastewater. The literatures, consisting of 1898 documents from 2000 to 2021 collected from the Web of Science database, were analyzed using bibliometric tools such as Bibliometrix package, CiteSpace, and VOSviewer. Document types, publication trends, subject categories, journals, institutions, countries, authors, keywords, and highly cited papers were analyzed. Research in this field has undergone three stages with the rapid development in the past 5 years. Environmental Sciences (24.42%) is the leading Web of Science category, and Engineering (48.37%) is the leading research area. China (38.46%) is the most productive country, followed by Spain (8.59%), Iran (8.11%), France (6.27%), and India (5.80%), while University of Barcelona (7.38%) is the most productive institute. Enric Brillas is the leading author and has the most publications (120 papers) and the highest h-index (58). The top five clusters include “landfill leachate”, “heterogeneous electro-Fenton”, “electrochemical oxidation”, “photoelectro-Fenton”, and “photocatalytic degradation”. With the rapidly growing number of electro-Fenton related studies, novel research interests and feasible large-scale applications, various techniques are proposed.
