Regardless of whether our HEB exhibits a HSPE or HAT mechanism, the crystallinity and crystal structure is crucial to the hydrogenation reaction. Hydrogen needs to have sufficient space and access to bond to platinum, if the crystal facets well defined hydrogen will not be activated and contribute to the catalysis. In this work, we investigate the difference in the synthesis methods of the HEB, comparing the molten aluminum flux growth method with highly defined facets to the arc melt synthesis, which produces undefined crystal facets. Here, we show that clear facets along the crystal edge are capable of being catalytically active.
