Electronic behavior of calcined material obtained from 2,2-diphenylphosphino-1,1-binaphthyldichloro palladium

The calcinations of 2,2-diphenylphosphino-1,1-binaphthyldichloro palladium under an argon atmosphere gave nano-sized Pd5P2/carbon cluster composite material. The ESR spectral examination of the material, and the reaction of either methylene blue or 2,3,5-trimethylhydroquinone in the presence of the material revealed that the calcined material has a visible light-responsive oxidation–reduction function through an electron transfer from the carbon clusters to the Pd5P2 particles.
