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

世界面临能源短缺的危机。由于化石燃料的枯竭及其燃烧造成的环境问题，人们迫切需要寻找清洁、廉价且可持续的新能源。氢作为潜在的下一代燃料受到了极大的关注，氢是地球上最丰富的元素之一。然而，氢以水（即海洋）形式与氧结合，或与化石燃料和无数碳氢化合物中的碳和其他元素结合而大量存在。目前，世界上现有的氢气供应大部分来自化石燃料，成本高昂，并且并不能消除导致全球气候变化的温室气体以及大量其他相关污染物的排放。因此，可持续制氢且不会产生环境问题的新技术
