铝镓铟锡合金水解产氢速率的调控方法

Control method on hydrogen production rate of aluminum gallium indium tin alloy

针对目前合金元素对铝水解制氢的活化机制尚不明晰,无法用来指导材料的配方设计与性能调控的问题,基于已有的实验经验结论和理论相图,进行了材料样本点的设计、合成、表征及产氢性能测试,并以合金速率峰值作为优化目标,分别探究了合金的物相组成和元素组成对产氢速率的耦合关系。结果显示:合金的元素组成与产氢峰值的耦合关系比物相组成的耦合关系具有更高的可信度,运用此耦合关系可以在一定程度上指导材料的定向设计,为未来此类材料的定向设计合成提供了一种新的思路。

Bulk Al-Ga-In-Sn alloys have the potential to be widely used in special processes such as field,military,and disaster relief due to their high safety,easy storage,and good hydrogen production performance.However,the activation mechanism for such materials is still unclear,and it is impossible to clearly guide the formulation and performance regulation of the materials.Therefore,the design and synthesis of material sample points are carried out in this paper based on the experimental experience conclusions in this field and theoretical phase diagrams,and the hydrolysis and hydrogen production properties of the above materials were characterized in detail.In this work,the peak of the hydrogen production rate of the material is chosen as the optimization target,and the coupling relationship between the phase composition and element composition and the hydrogen production rate of the aluminum gallium indium tin-based hydrolysis hydrogen production material is tried to be explored.Our research results show that the coupling relationship between the elemental composition of the alloy and the peak hydrogen production has higher credibility than the coupling relationship between the phase composition and the peak hydrogen production,and the use of this coupling relationship can guide the directional design of the material.It provides a new idea for the directional design and synthesis of such materials in the future.
