Abstract
Pd nanoparticles deposited by sol-immobilization on N-doped nanocarbon are studied in the direct synthesis of H2O2 and compared with undoped catalysts or prepared by the same Pd deposition method on active carbon (Vulcan XC-72). The Pd on N-CNT-like gives high productivities to H2O2, comparable to the best literature results. The introducing of nitrogen in the CNT-like material favors not only the dispersion of Pd (with a consequent improvement of the activity), but also the specific turnover. However, the introduction of these N functionalities on the surface has also a negative effect on the rate of H2O2 consecutive conversion to water.Pubblicazioni consigliate
