The result shows that the hydrogen storage properties increase remarkably after pure magnesium ball-milled with 10% TiFe(subscript 1-x)Cr (x=0, 0.3). Moreover, the chromium content also influences the hydrogen storage characteristics. Furthermore, the ball-milled composite of Mg+10%TiFe0.7Cr0.3 has the best hydrogen storage properties with hydrogenation capacity of 7.14% and dehydrogenation capacity of 6.91% at 613 K. In addition, the lower temperature of 493-573 K, the Cr-contained composite exhibits the best dehydrogenating kinetics.

Multiple-paths hydrogen abstraction reactions of fluorine -with CH_3OH have been investigated at the MP2/6-311 ++ g level. The potential energy surfaces for H-abstraction reaction from carbon atom and oxygen atom were given respectively. The results indicate that there is only one minimum energy path for hydrogen abstraction from carbon atom, while multiple paths were found for hydrogen abstraction from oxygen atom. All the stationary structures, frequencies as well as PES sketch of all channels were given, in which the dominant channel is by a five-member ring transition state. The calculated heat of reaction is 170.62 kj/mol for channel 1, 119.41 kJ/ mol for branch channel 6. The results are in good agreement with experimental data.
