Fig. 5: Theoretical calculations of PMS adsorption and activation on Al-Co TCPP and Ce-Co TCPP.

a Differential charge density for PMS adsorption on Al-Co TCPP (left) and Ce-Co TCPP (right). Yellow and cyan regions indicate electron accumulation and depletion, respectively. b, c Schematic illustration of the reaction pathways for Co(IV) = O generation on Ce-Co TCPP and Al-Co TCPP via PMS activation, respectively. The (*) denotes the adsorption site. d Energy profiles of the reaction pathways. Blue, brown, red, white, gray, light blue, and yellow-green spheres represent Co, C, O, H, N, Al, and Ce atoms.
