Solid surfaces are well known to mediate the dissociation of molecules via electronic interactions (heterogeneous catalysis). In particular, H2 dissociation on metal surfaces has been widely studied for several decades because it is an important step in hydrogenation reactions. The efficiency of the process depends on both the electronic properties of the metal surface and the surface microstructures. Enhanced efficiency and reduced cost are usually achieved by using nanoparticles, which have increased the surface-to-volume ratio and low-coordination atoms. Another approach is to optimize the local electronic states of the metal surface by doping, alloying with other elements, or by taking advantage of strong interactions between metal nanoparticles and the supporting substrate. Often these methods work together to tailor the adsorption properties on surfaces and show major efficiency enhancement.
