Abstract:
Single‐atom catalysts with ionic Pd active sites supported on nitrogen‐doped carbon nanotubes have been synthesized with a palladium content of 0.2–0.5 wt %. The Pd sites exhibited unexpectedly high stability up to 500 °C in a hydrogen atmosphere which was explained by coordination of the Pd ions by nitrogen‐containing fragments of graphene layers. The active sites showed a high rate of gas‐phase formic acid decomposition yielding hydrogen. An increase in Pd content was accompanied by the formation of metallic nanoparticles with a size of 1.2–1.4 nm and by a decrease in the catalytic activity. The high stability of the single‐atom Pd sites opens possibilities for using such catalysts in high‐temperature reactions.
