Abstract
- In this paper, the properties and evolution during the calcination process of hydrolysis by−products from the reaction between Al−based composites and water for hydrogen generation were systematically investigated. The results showed that the main phases of by−products included AlOOH and InSn4. The amorphous product possessed a large Brunauer−Emmett−Teller (BET) surface area with 276.77 m2/g and high porosity properties with 0.37 cm3/g. The phase transformation of by−products from AlOOH to γ−Al2O3, δ−Al2O3, and α−Al2O3 occurred during the calcination process. It appears that the by−products can be used as raw materials for the preparation of Al2O3 with different crystal structures. Discussion on the properties and evolution of hydrolysis by−products are beneficial to product reuse and recovery. In this way, the cost reduction of hydrogen production via Al−water reaction can be realized, promoting the sustainable development of hydrogen production from Al−water reaction.
