Surface-anchored N-based functional groups driven photoactivity of SrTiO₃.

ABSTRACT: Surface modification, including the anchoring of functional groups is a popular method to increase the photocatalytic activity of semiconductor photocatalysts. These species can trap excited electrons, thus prolonging the life of the charge carriers. N-containing functional groups are suitable for this purpose due to their high electron density. Here, we report a facile synthesis method for preparing interfacial N-based functional groups-modified and nitrogen-doped SrTiO₃ photocatalysts. Among the modified samples (with 0.42-11.14 at.% nominal nitrogen content), the one with 7.71 at.% nitrogen showed 6.4 times higher photooxidation efficiency for phenol and 2.2 times better photoreduction efficiency for CO₂ conversion than the unmodified SrTiO₃ reference.
