General Research Interests
  •  Membrane Separation Processes, Chemical Sensors
    • Specific Research Projects
  • Among challenges before utilizing membranes in harsh environments (e.g., high temperature, and steam presence)  are the choice of membrane materials and finding new ways to enhance their performance. We have shown that Silicon Carbide (SiC)  is a promising candidate for application in such conditions. The next step of our research is to enhance the performance of these membranes at the level to make them appropriate for applying in membrane reactors. Due to the fact that SiC membranes are highly permselective to hydrogen, ultimately they can be used for conducting  reactions such as water gas shift (WGS) or steam methane reforming (SMR) which are the main routes to produce hydrogen. This way hydrogen can be produced at lower costs and in less energy intensive processes.
