| Abstract |
The natural photosynthetic process has fascinated chemists for long due to its high specificity in solar energy conversion to sugar. In recent years, these efforts have intensified due to increasing emphasis on the development of carbon-free or carbon-neutral systems/technologies for production of solar fuel/chemicals. Utilizing the natural photosynthesis as blueprint, a number of covalent, and non-covalent donor-acceptor conjugate dyes have been studied as systems for CO2fixation. Although capable of efficient photoinduced intra- and intermolecular electron transfer (ET), they suffer from poor conversion efficiency and lack photostability. For enhanced efficiency and photostability, a variety of photocatalytic materials, such as inorganic frameworks and metal complexes have been developed and evaluated. However, their direct utilization remains limited due to one or more reasons, which include, low efficiency, poor selectivity, limited photostability and inability to work in visible light. This has led to emergence of the coupling of a suitable visible light active photocatalyst to an enzyme as an exciting avenue of research in this area. In this regard, we developed the photocatalyst/enzyme integrated solar chemical factory platform system that exemplified solar energy in synthesis of solar fuel & solar chemicals. The present work demonstrates successfully a new and potentially promising solar chemical factory platform system for the ultimate goal of utilization of solar energy in fuel & fine chemical synthesis. |
