摘要
氢能是全球公认的清洁能源,被认为是化石能源的理想替代品,具有广泛的市场前景。铝价格低廉、密度较低且能量密度高,铝水解产氢是一种有效提供氢能的方法。简述了铝水反应的原理,介绍了目前国内外主流的3种铝基材料水解制氢技术(纯铝与酸碱溶液反应、机械球磨法制备铝基复合材料、熔铸法制备铝基低熔点合金)的研究进展,并探讨了不同技术的反应原理、不同添加物的作用机理,对比了各种技术的特点,提出熔铸法制备低熔点合金将成为日后研究的重点,最后对未来熔铸法制备铝基低熔点合金的前景进行了展望。
Hydrogen energy is a globally recognized clean energy source and is considered to be an ideal alternative to fossil energy sources with a wide range of market prospects.Aluminum is inexpensive,less dense and has a high energy density.Hydrolysis of aluminum to produce hydrogen is an effective way to provide hydrogen energy.This article briefly describes the principle of aluminum-water reaction,and introduces the research progress of three mainstream aluminum-based materials at home and abroad(reaction of pure aluminum with acid-based solution,preparation of aluminum-based composites by mechanical ball milling method,preparation of aluminum-based low melting point alloys by melt casting method),the reaction principles of different techniques and the mechanism of action of different additives are also discussed,the characteristics of various techniques are compared,the idea of preparing low melting point alloys by melt casting as a focus of future research is put forward,and finally the prospect of preparing aluminium-based low melting point alloys by melt casting in the future is given.
