In this paper, the properties and evolution during the calcination process of hydrolysis by−products from Al‐water reaction for hydrogen generation were systematically investigated. The phase composition of by−products included AlOOH, InSn4, and trace phases. AlOOH constructed with flower‐like shape with micro/nano petals was obtained from the hydrolysis reaction. The phase transformation from AlOOH to γ−Al2O3, γ− Al2O3, and α−Al2O3 occurs during the calcination process. Discussion on the properties and evolution of hydrolysis by−pro...
