Open Ni site coupled with SO42- functionality to prompt the radical interconversion of OH ↔ SO4− exploited to decompose refractory pollutants
TL;DR: In this paper, a density functional theory (DFT) analysis was performed on SO42−-modified NiO (NiO (S)) to verify the benefits of surface Niδ+ (δ−≤ ǫ 2), SO42 −, or SO4 − NiO(S) was verified to contain abundant surface-labile O, facilitate electron transfer, and thus could increase H2O2 productivity.
