Abstract

Abstract: A novel material Bi1-x Gdx -BTC was obtained in situ via the solvothermal method. The effects of Gd 3+ substitution on the Bi-BTC structure and photocatalytic properties of Bi1-x Gdx -BTC were investigated. A standard Bi-BTC structure was observed in the X-ray diffraction spectra of the Bi1-x Gdx -BTC( x ≤ 0.07). However, some diffraction peaks were changed when the x is more than 0.07 due to the different ion radius. The developed Bi1-x Gdx -BTC samples exhibited higher photocatalytic activity than the pure Bi-BTC material. In RhB degradation experiments, the Bi1-x Gdx -BTC( x = 0.03 and x = 0.05) materials show degradation efficiency conversion of 71% within 60 min under visible light. The high photodegradation efficiency of Bi1-x Gdx -BTC could be ascribed to efficient charge transfer between Bi(III) ions and Gd(III) ions. Moreover, an active species trapping experiment confirmed that photo-generated ·O 2- and ·OH is the major species involved in RhB degradation.
