Resumen

This study presents a bibliometric review of scientific progress concerning the synergy between microbial fuel cells (MFCs) and textile dye remediation. Drawing from the Scopus database, the analysis spans the years 2005–2025 and applies systematic filters to derive a final corpus of 239 articles compatible with Bibliometrix software (4.2.1). Quantitative and structural analyses were conducted using RStudio with the Bibliometrix package, thematic network visualizations via VOSviewer (1.6.19), and frequency matrices, citation rates, and international collaboration indicators organized in Excel. Results reveal exponential growth in scholarly output, particularly within Environmental Sciences, Chemical Engineering, and Microbiology. China and India lead in publication volume, while countries such as the United Kingdom, United States, and Australia show high impact and international collaboration. Co-authorship networks reflect consolidated clusters, though connectivity gaps remain among emerging authors. Bioresource Technology is identified as a central journal, with terms like “wastewater treatment” and “microbial fuel cell” indicating thematic consolidation. Opportunities still exist in areas such as explainable artificial intelligence, integration with microalgae, and heavy metal remediation. Highly cited articles contribute key technical insights, highlighting hybrid configurations and advancements in electrode materials. Strategic mapping suggests that MFCs have evolved from experimental concepts to viable alternatives in industrial sustainability, though scalability, operational costs, and geographic representation remain significant challenges. This bibliometric review not only maps accumulated knowledge but also serves as a strategic compass for guiding future research toward integrated, accessible, and replicable bioelectrochemical technologies for textile dye treatment.
