By mechanical milling under hydrogen atmosphere, nanostructured B 4C can be achieved, in which hydrogen can be absorbed simultaneously. The IR measurements provided clear evidence of hydrogen trapping by boron. At elevated temperatures, molecular hydrogen and CH4 were detected in the desorption process. With increasing milling time, the desorption behavior of molecular hydrogen and CH4 changed substantially, which was suggested to be related to the structural change of BC4 during the milling process.
