Ti-O-O coordination bond caused visible light photocatalytic property of layered titanium oxide

The layered titanium oxide is a useful and unique precursor for the facile and rapid preparation of the peroxide layered titanium oxide H(1.07)Ti(1.73)O(4)·nH(2)O (HTO) crystal with enhanced visible light photoactivity. The H(2)O(2) molecules as peroxide chemicals rapidly enter into the interlayers...

description The layered titanium oxide is a useful and unique precursor for the facile and rapid preparation of the peroxide layered titanium oxide H(1.07)Ti(1.73)O(4)·nH(2)O (HTO) crystal with enhanced visible light photoactivity. The H(2)O(2) molecules as peroxide chemicals rapidly enter into the interlayers of HTO crystal, and coordinate with Ti within TiO(6) octahedron to form a mass of Ti-O-O coordination bond in the interlayers. The introduction of these Ti-O-O coordination bonds result in lowering the band gap of HTO, and promoting the separation efficiency of the photo induced electron–hole pairs. Meanwhile, the photocatalytic investigation indicates that such peroxide HTO crystal has the enhanced photocatalytic performance for RhB degradation and water splitting to generate oxygen under visible light irradiating.
