Abstract
En 中文
Atmospheric pollution has been increasing because of the rapid expansion of industrial and related activities. This growing pollution significantly affects human health and contaminates consumable resources. In particular, aerosol particulate matter plays a critical role in deteriorating air quality and poses serious health risks. Efforts to use these waste materials as a sustainable approach to reducing environmental pollution have recently gained attention. Atmospheric dust particles can serve as a valuable source of carbon-based materials through simple and efficient conversion methods. These dust particles, which often carry various metal ions, can yield functional carbon materials suitable for diverse applications. Similarly, waste spider web fibers commonly found in households contain adsorbed inorganic nanoparticles and represent another potential source of carbon. These micro-sized particles can be transformed from hazardous pollutants into useful materials if properly processed. This study reports a facile method for converting waste aerosol dust particles and spider web fibers collected from residential areas into functional carbon products. The morphological, structural, chemical, and optical properties of the resulting fibrous carbon were characterized using SEM, XRD, UV-vis, Raman, PL, and BET techniques. The results demonstrated that carbon materials derived from dust and spider webs exhibit reasonably good properties, highlighting their potential for CO2 sensing and electrochemical energy storage applications. This waste-derived carbon fiber can be processed further to improve its quality comparable to those of commercial carbon fibers.
