Fig. 1. Its crystal lattice consisted of one octahedral sheet sandwiched between two opposing tetrahedral sheets with Fe3+ replacing Mg2+ in the octahedral sheet by isomorphic substitution31. These Fe ions were situated within the central layer of VMT and thus were almost impossible to access PMS for activation, which was confirmed by the XANES results that there was a negligible difference between the XANES spectra at the Fe K-edge of the fresh and used Co@VMT MEM (Supplementary Fig. 16b). As such, the Co nanocatalysts were the critical catalytic active sites. Then, SO4
