It is found that the surface oxide is only a minor factor to affect the activation, while the magnitude of internal energy change in the alloy before and after hydrogenation is the controlling factor. The increases in the internal energy of the alloy, caused by oxide and the H-atoms entering tetrahedral or octahedral sites during hydrogenation, make the activation difficult.
