Development of MOF/Graphene Aerogel Composite for Ammonia Adsorption and Sensing

Metal-organic frameworks (MOFs) are a class of crystalline materials which have properties useful for gas separation, purification, and storage. While these MOFs can be extremely selective with the molecules they adsorb, the desorption processes can be slow and inconvenient. The objective of this project is to create and study a MOF/graphene aerogel composite which is

Development of Electrospun Nanofiber Nanoparticle Composites

The research question being explored in this report is whether or not electrospun nanofiber nanoparticle composites (ENNCs) with high loading capacities can be formulated and thermally annealed to form defect free mixed matrix membranes (MMMs) with applications in chemical separations. The general format of the research consists of formulating and testing out recipes for ENNCs,

Ammonia Detection Sensor through Structurally Flexible Metal-organic Frameworks

The research question for this project is to determine the effectiveness of an ammonia detecting sensor through the usage of metal-organic frameworks. The metal-organic frameworks used in this project change structure when ammonia is adsorbed into the pores of the material. This change in structure causes a shift in electrical resistivity and is the method

Creating a Defect Free Mixed Matrix Membrane using Annealing

The objective of this project is to eliminate the gaps that are formed when nanoparticles bond with polymer membranes in order to improve gas separation with an emphasis on carbon dioxide capture. It has been seen that thermally annealing electospun polymer mats embedded with nanoparticles, with pure polymer film casted membranes, via a temperature cycle

Study of Exfoliation Steps for Copper 2D MOFs

2D MOFs (metal organic frameworks) have shown promise in applications such as separation, catalysis, and medicine due to their tailorable structure and function, a result of high aspect ratios. This study aims to examine the exfoliation procedure of CuBDC MOFs under various tip sonicator conditions. Results have shown that sonication time and power are the

Creating metal organic frameworks with controllable particle size could lead to better greenhouse gas adsorption.
