Abstract

The investigation of photocatalysts used in degrading organic pollutant is highly valuable for ameliorating the environmental pollution. Herein, the g-C3N4/La2Ti2O7 heterojunction was successfully fabricated by an impregnation route. The as-obtained composite g-C3N4/La2Ti2O7 presents photocatalytic properties for degradation of the model organic pollutant rhodamine B (RhB) under visible light irradiation. A sequence of characterizations confirmed that the g-C3N4/La2Ti2O7 has an enhanced capability of light absorption than pristine g-C3N4 and La2Ti2O7. In the photocatalytic experiment, the degradation rate of RhB by 10% g-C3N4/La2Ti2O7 (g-C3N4 accounts for 10% in the total mass) composite is about 90%, which is 5 times pure La2Ti2O7 and 3 times pure g-C3N4. This impressive improvement could be ascribed to the formation of a heterostructure between La2Ti2O7 and g-C3N4, and improved migration efficiency of photogenerated electrons and holes.
