From: Independent tuning of size and coverage of supported Pt nanoparticles using atomic layer deposition

Precise control of coverage of Pt nanoparticles using ALD. Tuning the particle coverage at a fixed Pt loading by combining 0 (sample A), 20 (sample B), 30 (sample C), and 40 (sample D) O2-based Pt ALD cycles with 60 (sample A), 40 (sample B), 30 (sample C), and 20 (sample D) N2 *-based Pt ALD cycles. a ALD recipe scheme. For clarity, fewer than the real number of ALD cycles are schematically represented. b Experimental 2D GISAXS images. The dashed vertical lines indicate the q y-position of the main scattering lobe. c Schematic representations of the GISAXS results. The Pt loading, mean center-to-center particle distance 〈D〉, average particle width 〈W〉, and average particle height 〈H〉 are indicated. d SEM images with 50 nm scale bars
