Research Summary:

PhD Thesis: Nanosized zeolite synthesis and investigation of the synthesis mechanism:  The research concentrated on synthesis the nanosized zeolite which is different in size, showing the mechanism of the growth of the crystals. Other aim is finding the conditions to produce the 100 % crystalline silicalite-1 as small as possible.

M.S. Thesis: MTBE synthesis on H-Beta zeolite: Finding a catalyst and defining suitable reaction conditions to increase the catalytic conversion of the MTBE was the aim of the project. MTBE is the most preferred octane enhancer which is used for gasoline. The project also included the calculations for determining a general reaction rate expression (Funded by ITU Science and Technology Institute, Supervisor: Prof. Dr. Ayse Erdem-Senatalar, 2000).

 

Projects:

Development of mixed-matrix membranes for O2/N2 and CO2/CH4 separations: Preparation and characterization of zeolite filled polymeric gas separation membranes was the aim of the project. Membrane films were prepared by casting-evaporation technique and characterized by various methods including single gas permeability measurements (funded by ITU Research Fund, Supervisors: Prof. Dr. Ayse Erdem-Senatalar and Prof. Birgul Tantekin-Ersolmaz, 2001).

Development of nanosized antibacterial zeolites: Synthesis of nanosized zeolite A and imposing antibacterial properties to it by ion exchange are the main objectives of the project. This new material will be embedded to a polymeric matrix to cover the outer surface of the clothes (funded by the State and Planning Organization of Turkey, Supervisor: Prof. Dr. Ayse Erdem-Senatalar, 2005).
