Challenge: Amminex Emmisions Technology A/S (AET) has developed an unique concept for the safe storage, transport and delivery of ammonia in high density salts for the reduction of NOx. During start up of a diesel vehicle a fast release of the ammonia for the NOx reduction is limited by high binding energies of the metal halide salts which require high amounts of heat to be supplied and thereby lowers the total efficiencies. Furthermore, not all the ammonia is released from the pressed salt pellets, which decreases the usable storage capacity. Thus, AET is interested in R&D in exploring novel materials and storage concepts for ammonia with rapid and controlled adsorption/desorption kinetics.

Idea/solution: Electrospinning is a very efficient technology for nanofiber formation by electrostatic force. In this project, electrospinning will be used as shaping technique to design a 3-dimensional porous nanofiber composite that has the potential of increasing active surface area, facilitating fast absorption/desorption and improving mass transport.

Your task: You will explore the potential of electrospinning by designing and shaping composite nanofiber structures, consisting of adsorbents (MOF, zeolite) or salts which can be utilized for ammonia storage. The resulting composite nanofibers will be evaluated by several characterization methods, including Scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET) surface area analysis, Thermogravimetric analysis (TGA) and Differential scanning calorimetry (DSC).  In addition, you have the opportunity to work together with Amminex Emissions Technologies (AET), a leading supplier of DeNOx reduction technology to get feedback and test the nanofibers.
