The widespread use of bisphenol A (BPA), a plastic additive, is becoming a troubling trend due to its harmful effects on the environment. To date, graphene-based materials (GBMs) have piqued interest among researchers in the detection and remediation of BPA attributed to their salient properties of having large surface area, high conductivity, high functionalities, etc. Recent progress in GBMs has provided researchers with a wide array of synthesis techniques for various applications. Unfortunately, literature pertaining GBMs lagged in providing up-to-date research in BPA detection and remediation. Often, published review articles focused on the wide array of pollutants detection and remediation without a specific focus on a single pollutant. Hence, this review intends to reduce the knowledge gap by focusing on the recent studies pertaining usage of GBMs applications as electrochemical-based sensors and remediators via adsorption and photocatalysis of BPA. In sensing applications, GBMs sensors have evolved to be among the preferred choice for the detection of BPA. Provided that ample comprehensive reviews on the usage of GBMs as adsorbents and photocatalyst for various pollutants have been previously published, we focused our discussion solely on BPA as the model pollutant by providing up-to-date information on their synthesis route and performance ability. Certainly, this review will be useful to new entrants and experienced researchers intending to employ GBMs as the material of interest for the detection and remediation of BPA.
