Figure 3: The PEC water splitting method and the nanoparticle structure of the mesocrystal-based photoanodes The above diagram shows oxygen vacancies (Vo), and the movement of electrons (e-) and holes (h+). Using TEM (Transmission Electron Microscopy), it is possible to see the arrangement of nanoparticles inside the mesocrystals. SAED (Selected Area Electron Diffraction) was also carried out in order to examine the structure of the mesocrystals in more detail- indicating that the nanocrystals inside are highly ordered and aligned. The SEM image of the mesocrystal layer shows the disc-shaped mesocrystals and the network of pores and particles that aid light absorption and charge mobility, respectively.
