HAADF has been employed in various catalytic applications:
Nanoparticle Catalysts: HAADF is used to study the size, shape, and distribution of nanoparticles on support materials, which are critical parameters for their catalytic activity. Single-Atom Catalysts: The technique allows for the visualization of isolated metal atoms on supports, aiding in the design of highly efficient single-atom catalysts. Bimetallic Catalysts: HAADF helps in understanding the alloying and phase segregation in bimetallic systems, which can significantly impact catalytic properties. Environmental Catalysis: Researchers use HAADF to investigate catalysts for environmental applications, such as the removal of pollutants and greenhouse gases.
