Resum:
The development of efficient molecular photocatalytic systems for water reduction and production of high-value organic molecules is needed for more efficient synthetic methods and sustainable processes in renewable energy production. The photoreduction of organic molecules performed under mild conditions is limited and mostly catalyzed by noble metals. Therefore, synergistic merging of a photocatalyst and well-defined coordination metal complex enable the efficient photocatalytic synthesis of fuels together with their storage and reduction of organic molecules. In this regard, rational design of water-soluble catalyst based on earth-abundant elements is important to control these transformations. Chemical hydrogen storage are technologies to store and release hydrogen from the storage material through a chemical reaction. Various types of hydrogen storages have been developed, however they demand high temperature and energy. Moreover, the dehydrogenation process in many cases release environmentally unfavorable products. Consequently, new robust catalysts able to store hydrogen in chemical compounds are required as well as effective processes to implement the compounds successfully as practical hydrogen storage materials. Chapters 1 and 2 were dedicated to the motivations and methods
