Effect of acid catalysts on amorphous graphene oxide aerogel production

Abstract

The acids utilized in the production of graphene oxide aerogel underwent testing, revealing variations from the ones documented in the literature. The powder samples were produced by drying under ambient conditions. They were characterized, and the effect of the graphene oxide aerogels produced using these different acids on sound insulation was investigated. All reaction steps were the same in the study, except that different acids were added in the same molar amounts. Measurements were performed at 200 Hz–6000 Hz frequencies for sound absorption. Samples for sound absorption were prepared in 0.1 mm thickness. According to the results, the aerogel produced with acetic acid provided the best sound insulation at approximately 2000 Hz. We also attempted to explain how these acids affect sound insulation.
