摘要：
La-modified mesoporous TiO2 were synthesized via a sol-gel route using Pluronic P123 as template. The XRD and TEM results show that La loading favors the formation of anatase with smaller crystal size. The photocatalytic activity of the mesoporous anatase was tested in photocatalytic elimination of VOCs. The photocatalysts exhibited higher activity than that of the commercial photocatalyst (Degussa, P25) under either ultraviolet or visible light irradiation. The superior activity of the mesoporous anatase may be attributed to the synergic effects of the surface area, crystal size and loaded La species.
