Research Description

Description of Research
The ability to optimize various physical and chemical properties of materials, and to develop entirely new materials is at the heart of my research interest. The aim is to design, synthesize and characterized multifunctional materials which are materials that can be used for multiple functions (catalysis, conductivity, magnetism, luminescence, etc..) microwave, etc.). The approach used to reach our goal is the molecular building block approach in which specific molecular species are first synthesized then put together in a rational way to give specific structures with specific chemical and physical properties. The materials targeted have potential applications in Hydrogen storage, CO2 sequestration, environmental remediation, and Biodiesel production. Three main projects are currently investigated:

  1. Cluster-based Metal Organic Materials (CMOMs)
  2. Hybrid organic-inorganic phosphates and phosphonates (HOIPs)
  3. Natural products based catalysts for Biodiesel Production (NPCs)
