Innovations in catalytic understanding: A journey through advanced characterization

Abstract

This work provides a comprehensive overview of advanced characterisation techniques to unravel the molecular intricacies of catalytic processes. It begins with an introduction to catalytic processes and emphasises the importance of innovations in characterisation techniques, including SEM, XRD, UV-Vis, FTIR, RAMAN, XPS, NMR, TEM, AFM and the combined application of these techniques for improved catalytic investigation. The review of the development of catalytic processes provides a historical overview of progress and examines paradigm shifts in catalytic mechanisms and catalyst categories. Conventional microscopic and spectroscopic tools are revisited, highlighting the improvements in these techniques that provide insight into catalytic structures through surface analysis. Significant advances, including the application of computational techniques, in the study of catalysts are also discussed, focusing on state-of-the-art techniques that provide unprecedented detail on catalyst properties, mechanisms and processes. Comparative evaluations highlight the advantages and limitations of these techniques. The study concludes by identifying and overcoming challenges, anticipating prospects and emphasising the constant quest for innovation in understanding catalysts. By integrating developments in microscopic and spectroscopic methods, the study provides a comprehensive insight into how these tools improve the precision and depth of catalyst characterisation, driving innovation and future directions in catalysis research.
