The effect of temperature on the reaction of γ‐Al 2 O 3 ‐modified Al powders with distilled water was investigated. It was found that by increasing the temperature up to 40°C, the hydrogen generation speed can be enhanced one to two orders of magnitude relative to that at room temperature (18°C). X‐ray analyses and transmission electron microscopy observations revealed that the reaction by‐product at 40°C is bayerite (Al(OH) 3 ), which is chemically neutral. The present results imply that slightly increasing the temperature is an effective way to get the target hydrogen generation speed.
