The quantitative analysis clearly shows an increasing trend of H 2 uptake with higher surface area, which is linear for calcined samples (red symbols); for milled samples, the materials subjected to mild energy milling or short time display a similar behavior as their fresh counterpart, while a substantial increase in H 2 consumption is observed on the samples milled at high energy for 8h (HE-8h).
