The world faces the crisis of energy shortage. Due to the depletion of fossil fuels and resultant environmental problems from their combustion, there is a high demand of searching for new energy sources that are clean, inexpensive and sustainable. Significant attention has been paid to hydrogen as potentially a next generation of fuels, which is one of the most abundant elements in the earth. However, hydrogen is present in very large amount in combination with oxygen in the form of water (i.e. the ocean) or in combination with carbon and other elements in fossil fuels and innumerable hydrocarbon compounds. At present, most of the world's current supply of hydrogen gas is derived from fossil fuels, which is costly and does not eliminate the emission of Green House Gases that results in the global climate change as well as a large mount of other related pollutants. Therefore, novel technologies for sustainable hydrogen production without generating environmental problems
