Abstract
The present invention describes a process for producing nanostructured material, produced from polymer waste doped with alkaline metals and/or alkaline earth metals, which is capable of capturing and storing CO. The process for obtaining the material uses waste generated by the polymer industry and is therefore environmentally sustainable. The product produced, that is, the nanostructured material, shows high COabsorption capacity, being able to absorb up to 80% by weight in mass in CO. In addition, the product produced shows low density, an important characteristic for application in vehicles. Therefore, the product obtained can be used for capturing and storing COemitted by different emission sources, mainly mobile sources such as vehicles, but can also be used in industries such as the mining industry, oil industry, inter alia, in addition to the automotive industry.
