In this study, Sn-doped Pt/SiO2 catalysts were used for the selective regeneration of NADH. By disturbing the Pt ensemble and altering NAD(+) adsorption, the catalyst achieved a selectivity of 90%.
H-2-Driven NADH regeneration has long suffered from low selectivity when non-enzymatic, particularly heterogeneous catalysts, are used. In addition to the unselective nature of the catalysts, the typically unmeasured NAD(+) conversion has inevitably hindered catalyst development. Here we report Sn-doped Pt/SiO2 catalysts for the selective regeneration of NADH and show that doping Pt/SiO2 with 10 at% Sn can deliver a selectivity of 90% (at full conversion) using H-2. We propose that this is a result of Sn disturbing the Pt ensemble, altering the mode of NAD(+) adsorption and directing the reduction to the 1,4-position of the nicotinamide ring.
