Dft-based approach
Webgested: linear-scaling approaches [6{32], relying on the sparsity of the density matrix [33], DFT-based tight-binding (DFTB) methods [34{36] which reduce the nu-merical scaling using model Hamiltonians. Moreover, signi cant e orts have gone towards developing orbital-free DFT [36, 37] approaches using density-dependent kinetic energy functionals.

WebIt was clearly that the degradation process of MB was switchable when the attacked ROS were different. Based on the DFT analysis (S and N were the highest reactive sites under ROS attack), and the GC–MS results, the possible degradation pathway of MB with only light irration or under light/Fenton reaction were depicted in Fig. S11 and Fig. S12.
