Abstract:: 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
