Análise bibliométrica da produção do óxido de grafeno reduzido em aplicações energéticas

Abstract

This work presents a bibliometric analysis of reduced graphene oxide (rGO), using data extracted from the Scopus database and processed through the R programming language with the support of the Bibliometrix and Biblioshiny packages. The study mapped the evolution of scientific production from 2012 to 2025, revealing continuous growth, strong interdisciplinarity, and broad geographical distribution, with notable contributions from India, China, and Korea. Publications are primarily focused on synthesis routes, material characterization, and technological applications, especially in electrochemical devices and perovskite solar cells. Network analyses identified three main thematic clusters: synthesis methodologies, electrochemical performance, and the integration of rGO in photovoltaic systems. The results also highlighted significant gaps, such as variability in synthesis routes, lack of standardization in characterization methods, and limited studies addressing long-term operational stability. The findings indicate that rGO is a promising and versatile material with increasing scientific relevance and strong potential for advanced technological applications; however, its consolidation requires methodological standardization, scalability assessments, and deeper investigations into device-level durability.
