Synthesis and characterization of Metal-organic Frameworks for oxygen and reactive gas-adsorption

 

 

Level of work

Master or Diploma in Chemistry, Chemical Engineering, Materials Science or similar

Motivation

Metal-organic frameworks (MOFs) have attracted the attention of the scientific community in the last fifteen years, giving rise to an extraordinary amount of work in terms of fundamental research. These microporous materials, due to their exceptional properties (surface area, pore volume, tunability) have indeed potential application in a wide variety of technological fields, ranging from gas storage and separation to catalysis, luminescence, drug delivery, sensing, etc. Regarding the storage of gases in porous materials, different industrial sectors, related to energy, environmental technology and health care, are seeking for new technological solutions able to ensure a safe storage of considerable amount of gases into units with reduced volumes. Oxygen storage is of technical interest for the development of breathing assistance devices as well as for the aerospace industries. Materials able to adsorb reactive gases are applied in the textile industry for the development of protecting clothes.

Project description

In the proposed project continuous flow processes will be deliberately developed and employed to achieve a high-precision and high performance synthesis of new or re-designed MOFs at relevant scale. Two main application scenarios of strong industrial relevance will be particularly considered in the project – namely oxygen storage and H2S and NH3 selective adsorption – being in continuation and accordance with previous and ongoing research activities at Fraunhofer ICT. In the first phase of the project the materials will be synthesised and fully characterized through surface analyses, x-ray diffraction, thermogravimetric analysis and FT-IR. Subsequently these materials will be tested and evaluated in terms of gas storage and adsorption capacity up to 100 bar.

Tasks

  • Development of synthetic protocols for the preparation of MOFs
  • Characterization of the synthesized materials
  • Gas adsorption capacity measurements
  • Processing of the data:
    • Parameter analysis of the MOF performance activities

Requirements

  • Study of chemistry, chemical engineering or materials science
  • Practical synthetic laboratory experience would be beneficial
  • Good language skills in German or English
  • High level of motivation
  • Ability to work independently

Begin

By agreement
