Abstract

In recent years, renewable energy resources and global environmental problems have become an increasingly vital and burning subject both in political and scientific sectors. Fossil fuels are the principle source of energy for transportation. On the other hand, chief source of CO2 emission is the burning of fossil fuels. Fuel cell powered electricity and transportation will most probably be the future to solve addressed problems but there is a big difficulty to generate cheap and pure clean fuels like hydrogen for such systems. Best possibility is to utilize solar energy for the production of hydrogen from water. At present, there is no efficient system available that makes use of solar energy effectively to produce hydrogen from water.  Photosynthesis is an excellent model for an artificial solar energy conversion system to clean fuel and oxygen evolving complex (OEC). Getting inspiration from nature, there is a continuous effort to design an artificial photosynthetic system based upon harnessing the solar energy and capable of utilizing it efficiently for water splitting to generate oxygen and hydrogen. Efficient catalytic water splitting using solar energy is a challenging research topic. Upheaval task is to establish an efficient and stable oxygen-evolving catalyst. There are many water splitting systems based on noble metal complexes and metal oxide catalysts but none of these systems have proven effective overall efficiency for water splitting. Present report describes a system based on oxo-bridged ruthenium catalyst for water splitting. Future perspective of this work is to design a model system of an active multielectron transfer site based on new robust catalytic materials for water splitting in artificial PS-II to generate clean fuel.
