Thesis Abstract

Abstract
The demand for efficient gas separation technologies has been on the rise due to increasing industrial applications and environmental concerns. Metal-organic frameworks (MOFs) have emerged as promising materials for gas separation due to their tunable porosity and high surface area. This thesis focuses on the synthesis and characterization of novel MOFs for gas separation applications. The study begins with a comprehensive introduction to the importance of gas separation technologies in various industries and the potential of MOFs in this field. The background of the study provides an overview of existing research on MOFs for gas separation and highlights the gaps in current knowledge. The problem statement identifies the need for new MOFs with improved gas separation properties to address specific industrial challenges. The objectives of the study include the synthesis of novel MOFs using different metal ions and organic linkers, as well as the systematic characterization of their structural and gas separation properties. The limitations of the study are acknowledged, particularly in terms of the scalability and industrial applicability of the synthesized MOFs. The scope of the study outlines the specific gases targeted for separation and the experimental techniques to be employed. The significance of the study lies in the potential impact of developing new MOFs with enhanced gas separation capabilities, which could lead to more energy-efficient processes and reduced environmental impact. The structure of the thesis is presented, detailing the organization of chapters and sections for a coherent presentation of research findings. A thorough literature review is conducted in Chapter Two, exploring the latest advancements in MOF synthesis methods, gas adsorption mechanisms, and gas separation performance of existing MOFs. The review highlights key factors influencing gas selectivity and permeability in MOFs, providing a foundation for the experimental work in this study. Chapter Three outlines the research methodology, including the synthesis procedures for different MOFs, characterization techniques such as X-ray diffraction and gas adsorption analysis, and the evaluation of gas separation performance using permeation tests. The chapter also discusses the optimization of synthesis parameters and the validation of experimental results. Chapter Four presents a detailed discussion of the findings obtained from the synthesis and characterization of novel MOFs. The structural properties, porosity characteristics, and gas separation performance of each MOF are analyzed and compared. Factors influencing gas selectivity and permeability are identified, and potential strategies for improving separation efficiency are discussed. In the concluding Chapter Five, the key findings of the study are summarized, emphasizing the significance of the synthesized MOFs for gas separation applications. The implications of the research results for industrial gas separation processes are discussed, along with recommendations for future research directions. Overall, this thesis contributes to the advancement of MOF-based gas separation technologies and provides valuable insights for researchers and practitioners in the field.
