Facile one-pot hydrothermal method to prepare Sn(Ⅱ) and N co-doped TiO2 photocatalyst for water splitting under visible light irradiation
文献摘要：
In this paper,a visible light-responsive Sn2+and N co-doped TiO2 photocatalyst was prepared by facile one-pot hydrothermal method.All as-prepared samples were characterized in detail by a series of characterization approaches.The results showed that the Sn2+ and N ele-ments were co-doped into TiO2,while the catalyst still maintains anatase crystal structure and gets irregular little nanocluster in diameter of 9-10 nm with higher specific surface area.The absorption edge of Sn2+ and N co-doped TiO2 extends to the visible light region.Compared with Sn2+-doped TiO2 and N-TiO2,the absorption edges have obvious red-shift of about 50 and 70 nm,respectively.The synergistic effect of O 2p-N 2p and O 2p-Sn 5s hybridization to form impurity levels is the main reason for the red-shift.The hydrogen production performance of the Sn2+ and N co-doping TiO2 (n(N)/n(Ti)=1) catalyst reached the maximum value of 0.37 mmol·h-1·g-1 under visible light,which is higher than that of N-doped TiO2 and Sn2+-doped TiO2 singly.This result is due to the wider visible light region-responsive ability of Sn2+ and N co-doped into TiO2.Furthermore,mild hydrothermal methods will not make the Sn2+ oxidized to Sn4+,which make the catalysts still maintain high photocatalytic performance.This work provides a simple and mild method for the preparation of dual-element co-doped TiO2 with high crystallinity,excellent performance and broad application prospects.
