Progress, Challenge, and Perspective of Bimetallic TiO2-Based Photocatalysts
Figure 7
The effect of calcination temperature on the structure of Au/Pd bimetallic nanoparticles. (a) High resolution HAADF images with z-contrast for Au/Pd nanoparticles calcined at 350°C, 400°C, and 700°C. (b) The yellow circles show gold-rich areas (palladium gives a light contrast than gold as a lighter element) [33].
