Heteroatom-doped porous carbon nanospheres for selective oxidation of alcohols

The oxidation of alcohols to carbonyl compounds is a fundamentally important organic transformation, and thus, extensive effort has been devoted to verifying the catalytic activity and, in particular, to achieving a selectivity of heterogeneous catalysts in the oxidation of alcohols [1, 2]. Recently, Au, Pd, Mn2O3, Fe3O4, TiO2- based hybrid nanoparticles were found to Show high efficiency as a catalyst for the oxidation of alcohols. Herein, we report the synthesis of Pd@P-doped Carbon spheres and their high catalytic activity resulting from entirely exposed Pd particles and highly porous Carbon support. This hybrid Pd@P-doped Carbon spheres efficiently catalyze the oxidation of benzyl alcohol as well as that of various substituted benzyl alcohols. Combined high catalytic activity and thermal stability were achieved with a well-structured nanoparticles which were synthesized by a hydrothermal method for carbonization of glucose in presence of phosphine as phosphor precursor. Pd nanoparticles were then produced on phosphorous doped porous carbon spheres
