Abstract

This outline of the thesis elucidates the features organizing structural information by discussion of tuning colloidal & molecular structures to facilitate coupled and decoupled CO₂ reduction. After that I will define the problems that were encountered to complete this thesis work and thereafter I will discuss organizing structural information in chapters 3 & 4. We will discuss crystallization and gelation in the context of colloids and study how factors like pH, volume fraction, charge and time plays an important role facilitating this critical phenomena. We have also developed a phenomenological model which is reminiscent of Yang’s lattice gas model giving us an edge in understanding this gelation phenomenon. Thereafter in chapters 5 & 6 we will address how supramolecular interactions and heterogeneity when chopped down to simple molecular species like corrole interacting with transition metals like Co & Mn can lead to CO₂RR cascaded with C-C coupling and then I will conclude. The advantages that the metallocorroles possess give us an edge over tailoring CO₂ reduced to multi-electron reduced products with selectivity for C2 products like alcohols and acids as well as study the underlying mechanistic insight with spectroscopy and theoretical tools.
