文摘
Hybrid Pt鈥揅o:ZnO nanostructure photocatalysts were prepared via a facile two-step synthetic strategy. SPS and TPV investigations demonstrate the existence of the synergetic effect between Pt and Co dopants. Such synergetic effect could make use of visible photons as well as facilitates the separation of photogenerated charges to prevent recombination, effectively prolongating the charges lifetime to participate photocatalytic reaction. The synergetic effect exist in Pt鈥揅o:ZnO inducing as high as 7.7-fold in photovoltaic response and 10-fold in the photo鈥揳ctivity for hybrids compared to Co:ZnO.
