【Abstract】 It is difficult to activate TiFe alloy for hydrogen sorption.In this report amicro-electric-arc oxidation treatment was developed and it was found that TiFe alloycould be activated at the room temperature by such a surface oxidation treatment.It is be-lieved that the surface oxidation treatment broke the inert oxide film on the original surfaceand produced a series of new oxides with different compositions,structures and chemicalstates,which provide new catalytic centers for dissociatve hydrogen chemisorption.更多还原
