Porous materials have the potential to be used as exceptional carbon capture materials, as well as for trapping and releasing other useful gases, such as those used in medical applications. They work, because they contain small holes where these gases can be trapped. Unfortunately, finding gas inside these holes experimentally is incredibly difficult, making it challenging to make better porous materials. In this project, I will use extreme pressures to saturate these holes with gas molecules, allowing us to ‘see’ them. Not only will this mean that better porous materials can be designed and made, but will provide a unique approach to storing and trapping gases to be used in a variety of applications, from the energy to medical sectors.
