Abstract

The petroleum industry is a global necessity; however, it is responsible for ocean spills which devastates the wildlife and ecology. Throughout the years there has been a decrease in ocean spills, however, they have not been totally eliminated. Current oil spill cleaning methods are not sufficient; for example, dispersants are toxic towards wildlife. Metal graphite sponges can be used to clean oil spills due to their oleophilic highly porous sponge matrix, without using surfactants that persist in the environment long after the spill has dispersed. The process of making graphite sponge is easily scalable and template-free: mix the solution, expand in a vacuum oven, and anneal in a tube-furnace. Previously this lab made a graphite sponge that is oleophilic and hydrophobic. This ultra-thin graphite sponge was made to be versatile by using abundant natural resources to make a material that functions even when pulverized. By adding iron and cobalt metals to the sponge, the sponge will become magnetic, which would help in retrieving the sponge from the ocean. In order to characterize the sponge, we will use SEM to see the porous network, XRD to verify composition, contact angle measurements to verify hydrophobicity and oleophilicity, and FTIR to investigate chemical bonds.
