- Platinum nanoparticles of diameter ∼2 nm are importantcatalysts in carbon monoxide oxidation to carbondioxide. Platinum crystallizes in a face-centered cubicarrangement with an edge length of 3.924 Å. (a) Estimatehow many platinum atoms would fit into a 2.0-nmsphere; the volume of a sphere is (4/3)π r3. Recall that1 A° = 1 x 10-10 m and 1 nm = 1 x 10-9 m. (b) Estimatehow many platinum atoms are on the surface of a 2.0-nmPt sphere, using the surface area of a sphere (4π r2) andassuming that the “footprint” of one Pt atom can be estimatedfrom its atomic diameter of 2.8 A° . (c) Using yourresults from (a) and (b), calculate the percentage of Pt atomsthat are on the surface of a 2.0-nm nanoparticle. (d)Repeat these calculations for a 5.0-nm platinum nanoparticle.(e) Which size of nanoparticle would you expect tobe more catalytically active and why?Solve the following mathematical operations: 1. a(3y) dy 2.
