Abstract:
Graphene is a very new material that has been receiving a significant amount of attention for its many desirable qualities, particularly its electrical properties and strong molecular structure. Because graphene is such a new material, many of its properties are currently being investigated and being discovered. One area of research that graphene has recently been used in is nanofiltration, which encompasses materials that uses nanometer sized cylindrical pores that allows others materials to diffuse through it and filter out any unwanted products. A theoretical graphene structure uses hydrogen impurities to create an octagonal opening, which could allow gas particles to pass through. Although this structure has not yet been created, this material could have applications in hydrogen filtration, which is essential in creating hydrogen fuel cells which require high purity hydrogen gas. Using hydrogen as a fuel source would be cleaner than the current energy sources we use today, and graphene nanofiltration could facilitate the widespread use of this fuel source. The greatest limitation that graphene currently has is its capability of being synthesized at an industrial level. Currently, the largest piece of graphene created is 0.5 millimeters in diameter, which is not enough to for any of the current application that graphene is being associated with. One of the most promising and inexpensive synthesizing procedures has been chemical vapor deposition. This procedure involves exposing a carbon saturated transition to hydrocarbon gas at a high temperature, which causes a thin layer of carbon to precipitate. Graphene is a material with the potential to improve many of the technologies we use today, but until it is capable of being made at a high volume, it will only be speculation.
