Catalytic and Co-Catalytic Activity of Different Shapes and Sizes of Platinum Nanostructures

Abstract

Pt nanostructures of different shapes (PtNS, PtNP-1, PtNP-2) have been synthesized. During characterization, it is observed that PtNP-2-TiO2 addition exhibits the highest photo activity as compared to lowest photo activity by other shapes of Pt nanostructures. The same amount of PtNPs addition in Pt-TiO2 composite always enhanced the degradation rate of reacting substrates. The nanoparticle’s surface morphology and surrounding adsorbed contaminants have vital role for exhibiting optimum activity for a catalysis reaction.
