Research Progress on Hydrogen Production Technology for Aluminum-Based Materials
Hydrogen energy is a globally recognized clean energy source and is considered to be an ideal alternative to fos-sil energy sources with a wide range of market prospects.Aluminum is inexpensive,less dense and has a high energy densi-ty.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 reac-tion principles of different techniques and the mechanism of action of different additives are also discussed,the characteris-tics of various techniques are compared,the idea of preparing low melting point alloys by melt casting as a focus of future re-search is put forward,and finally the prospect of preparing aluminium-based low melting point alloys by melt casting in the future is given.
