摘要
金属氧化物两步热化学循环分解水制氢技术集太阳能储备与氢能制备于一体,是当前新能源研究和开发领域的热点之一。本文介绍了该技术制氢原理,综述了其关键材料金属氧化物体系和太阳能反应器的研究进展,分析了制约该技术规模化应用的"瓶颈"因素。最后,对近年出现的基于金属氧化物两步热化学循环分解水制氢的两步法蒸气重整新工艺的原理和金属氧化物材料研究进行了介绍,并对该领域的发展趋势进行了展望。
The process of two-step water-splitting thermochemical cycle based on metal oxide redox system is a solar energy storage and hydrogen production technology, which has become one focus in new energy research and development field. The principle of this hydrogen production technology is introduced, research progress of key materials--metal oxide systems and solar reactor are reviewed, and ＂ bottleneck ＂ on the way to largescale application is analyzed. In the end, two-step steam reforming of methane （two-step SRM） derived from two-step water-splitting thermochemical cycle based on metal oxide redox system in recent years, as well as metal oxide materials involved in this novel technology are discussed. Furthermore, research direction in this field is proposed.
