Bibliometric analysis on conducting polymer sensors for ammonia gas detection using Scopus database

Abstract

Conducting polymers (CPs) based sensing materials have emerged as a prominent option for the sensitive detection of gaseous ammonia (NH₃) due to their costeffectiveness, ease of production, and increased sensing performance. Although more than 1400 articles published in the past decades, no bibliometric analysis which can highlight the publication trend and research clusters within the scope of conducting polymerbased sensors for ammonia detection (CPAD) is available in the literature. The aim of this bibliometric analysis is to document the research trends of CPAD during the last 27 years, since the inception of the first report on conducting polymer as potential NH₃ gas sensor which has been published in 1994. The bibliometric analysis was carried out using VOS viewer and Publish or Perish software to analyze keywords trend, the impact of the scientific community, publishing trends among the authors, institutions, and countries. The review discovered that over 80% of the relevant papers produced after 1994, based on bibliographical examination of 1476 Scopus indexed articles. Citation analysis was used to identify key authors and articles that shaped the evolution of this literature. Overall, this bibliometric approach allows us to analyze the evolution of a CPAD field while also offering insights on the field's growing areas.
