Abstract [en]

The recent development of technology has enabled us explore new depths and gain much understanding of the world around us and have helped us understand concepts which once just seemed like science fiction. Study of modern materials after they are synthesized is a branch of science called characterization of materials or material science. Various characterization techniques have been developed over the years. We can perform bulk analysis as well as study morphological characteristics at micrometer to nanometer scale features using high-end electron microscopes such as Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM), Atomic Force Microscope (AFM) etc.

In this Master thesis study we focus on 3D characterization and morphological analysis of catalyst systems using MicroCT and SEM with focus on Lindlar catalysts which were showing variations in performance. New methods of sample preparation were developed during this phase which helped in studying the same samples in MicroCT and SEM. Factors which affect performance of Lindlar catalyst was also found to be consistent with previous knowledge of catalysts. Morphology of Lindlar catalyst was studied successfully. However, further studies of Lindlar catalysts are suggested using TEM as a continuum of this project.
