Ni–Pd bimetallic catalysts for the direct synthesis of H2O2 – unusual enhancement of Pd activity in the presence of Ni†
Abstract
Direct synthesis of hydrogen peroxide from molecular H2 and O2 is one of the challenging reactions for several decades in terms of catalyst selection, stability and selectivity. Herein, we report a bimetallic NiPd nanocatalyst showing unusually high, three times higher activity compared to Pd nanocatalysts. The catalyst also shows very long life time, 72 h, with high activity under harsh acidic conditions.
