Function of Lattice Defects toward Photocatalytic Processes: View of Electronic Driven Force
Figure 1
Main steps occurring in the photoelectrochemical mechanism. ((i) Photon absorption and electron-hole pair generation. (ii) Charge separation and migration (a) to surface reaction sites or (b) to recombination sites. (iii) Surface chemical reactions at surface active sites, donor oxidation at valence-band hole, or acceptor reduction at electron center.)
