Abstract

Abstract : Comparison of Pd catalyst performance before and after N/O doping. Schematic diagram of anchoring Pd nanoparticles on the surface of N and O doped CNT. Abstract : The direct synthesis of hydrogen peroxide (H2 O2 ) was studied by using a series of catalysts Pd/CNT-X (X = N, O) prepared by ethylene glycol reduction, which allows for better control of Pd nanoparticle size and catalyst hydrophilicity. The doping of both N and O into a carbon carrier could anchor Pd nanoparticles and enhance the hydrophilicity of catalysts, which would lead to significantly enhanced H2 O2 productivity and stability compared to the original catalyst Pd/CNT. Detailed characterization indicated that this improvement was due to selective tuning of the Pd nanoparticle size, Pd 0 /Pd 2+ ratio and catalyst hydrophilicity.
