This study analyzes research articles worldwide on nanostructured materials used to efficiently deal with the removal of VOCs from air. VOCs affect both indoors and outdoors and bring significant negative effects on health and the environment. This, therefore, requires innovative ways of removing VOCs. We also mentioned the most promising VOC removal methods such as adsorption, photocatalysis, and catalytic oxidation which are quite effective. This study uses scientific analysis of data gathered from Scopus for the years spanning from 2015 to 2025(till date) found 294 documents. Keywords associated with VOCs and nanostructured materials were used to search the literature and then all the data was carefully checked and screened. Examining trends, co-authorships, partnerships in keywords and major themes were achieved by using VOS viewer and Cite Space. It is found that most work has centered on metal oxide and carbon-based nanomaterials, due in large part to China, the United States and India. They demonstrate how specialists and countries collaborate to inspire innovation. Journal sources reveal leaders in the field. Future studies will focus on reliability, safety and production of nanomaterials. These insights show the potential of nanomaterial-based approaches, which offer prospects for reducing industrial emissions and indoor air cleaning to enhance sustainability and well-being. This research gives an in-depth look at areas where new research is required and provides useful guidance for scientists, officials and companies interested in improving nanomaterial-assisted ways to remove VOCs and promote better air quality.
