Purpose: This study aimed to construct a knowledge map and analyze publications in the field of nanomaterials using data from the Web of Science (WoS) database.
Method: This applied research employed a scientometric approach. Data was extracted from WoS using the advanced search function with the keyword "nanomaterials," yielding 4,637 records. After cleaning and standardizing the data, it was input into scientometric software and generated the desired maps. Bibliometrix in R was used for visualization.
Findings: The findings indicated that a total of 4,637 information records in the subject area were indexed in this database. China ranks first with 3,459 information records, followed by India and the United States in second and third place with 1,370 and 884 information records, respectively. Iran ranks fourth with 589 information records. More than 95 percent of scientific publications are in English, with Chinese ranking second, accounting for 166 records. Islamic Azad University in Iran holds the top position with 105 records. The most frequently occurring keyword is with a frequency
of 847. Among the keywords in the indexed scientific records, the keywords nanoparticles and nanomaterials have the highest co-occurrence with 14 repetitions. The indexed scientific records were categorized into five clusters: nanomaterials, carbon nanotubes, mechanical properties, photocatalysis, and carbon nanomaterials, with the carbon nanomaterials cluster having reached maturity. The clusters of photocatalyst and mechanical properties are developed yet distinct. Carbon nanotubes belong to the peripheral cluster segment, which is either emerging or declining, while the nanomaterials cluster is situated in the central segment, albeit underdeveloped. Therefore, this field of technology, despite its history of over 30 years, still has significant room for improvement.
