Here we demonstrate the catalytic transparency of h-BN to Pt metal substrate for hydrogenation. We analysed extent of h-BN hydrogenation on various Pt single-oriented crystals via hydrogen plasma treatment; the rate of hydrogenation follows the order Pt (110) ＜ Pt (111) ＜ Pt (100). It revealed that the catalytic activity of Pt inducing the h-BN hydrogenation is related to the difference of adsorption energy of hydrogen on Pt surface orientation. The h-BN thickness-dependent experimental results have demonstrated that the monolayer h-BN has catalytic transparency to Pt surface for the hydrogenation. Moreover, we suggested that the h-BN nanomesh, formed by arrangement of h-BN on the metal surface, can be one of factor to explain different progress of h-BN hydrogenation on each Pt crystals. This tendency was also observed in conversion reaction of h-BN, since it is a phenomenon based on the hydrogenation of specific materials. |
