海水电解制氢研究进展OA北大核心CSTPCD

With the deep development of clean energy and the innovation of hydrogen production technology by electrolysis,hydrogen production by seawater electrolysis has become one of the re-search hotspots.The ocean,as the most abundant water resources on earth,is an excellent choice to achieve large-scale hydrogen production by electrolytic water from the perspective of electrolytic wa-ter.However,the material composition of seawater is rich,so the existing electrolytic water technol-ogy can not be used in scale to produce hydrogen from seawater.The general progress of hydrogen production by direct electrolysis in seawater was reviewed,and the mechanism of hydrogen evolution and oxygen evolution involved in the reaction of electrolytic seawater was described in detail.Then,the research progress of key catalysts used in seawater electrolysis was summarized and analyzed,and the current challenges and technical progress in this field were summarized and prospected.Di-rect hydrogen production from seawater is still facing great challenges from laboratory to industrial-ization,and its future development still needs to go through a lot of theoretical research and practical tests.
