Alloy catalysts are commonly employed for selective hydrogenation of organic molecules due to their enhanced selectivity than individual components but their structural and electronic effect(s) are not yet clear. By a rapid quenching technique it is found that active and selective catalyst can be produced from Raney Ni50Al50 alloy, which show exceptional high selectivity towards H2O2 via anthraquinone reduction-oxidation processes. We aim to characterise hydrogenic intermediate species in hydrogen atmosphere using INS and DFT (density functional theory) calculations. In particular we want to determine the relative populations of these intermediates in combination with our in house characterisations (ATR-IR, TPD) which will lead us to elucidate the structural and electronic effect(s) on them.
