7958 745 Pt/WO2.72 TEM The height and width of the as-formed WO2.72 nanoplates were 10–25 nm and 20–50 nm, respectively. The Pt nanoparticle surfaces were predominantly spherical, with average sizes of 10–15 nm. The high-resolution TEM (HRTEM) image in Fig. 1c revealed distinct lattice fringes of 0.317 nm, 0.378 nm, and 0.294 nm, corresponding to the (010), (004), and (402) lattice planes of WO2.72 nanoplates, respectively. Distinct lattice fringes of 0.226 nm and 0.196 nm corresponded to the (111) and (200) lattice planes of Pt nanoparticles, respectively.
