英文摘要Identifying the prerequisite of inducing band-like doping levels in wide bandgap metal oxides is a crucial yet open question. Herein, taking boron (B) and nitrogen (N) codoped anatase TiO2 as an example and combining density functional theory calculation with machine learning, it has been revealed that the band-like doping levels mainly originate from a strong p-d coupling between O/N-p pi and Ti-t2g orbitals. Significantly, the existence of strong p-d coupling is an intrinsic characteristic of anatase TiO2 determined entirely by crystal symmetry, which can be used as a universal criterion to predict whether band-like doping levels can be induced in other metal oxides, and the criterion has been fully verified on rutile and brookite TiO2, ScTaO4, WO3, SnO2 and MgTa2O6. Besides, the strong p-d coupling offers a theoretical basis for the long-held empirical understanding that uniform doping is important in achieving stronger visible light absorption for wide bandgap metal oxide photocatalysts. Overall, the uncovered strong p-d coupling provides a simple yet profound guideline for bandgap engineering of metal oxides. The existence of strong p-d coupling between O/N-p pi and metal t2g orbitals is the prerequisite for inducing band-like N doping levels.
