Electron tomography (ET) is a powerful imaging technique used to obtain three-dimensional (3D) reconstructions of nano-sized objects. By acquiring a series of two-dimensional (2D) images at different tilt angles, ET allows for detailed visualization of the internal structure of materials at the nanometer scale. This is particularly useful in the field of catalysis, where understanding the morphology, composition, and distribution of catalytic materials is critical for the design of more efficient catalysts.
