Coupling of Nanocrystalline Anatase TiO(2) to Porous Nanosized LaFeO(3) for Efficient Visible-Light Photocatalytic Degradation of Pollutants
In this work we have successfully fabricated nanocrystalline anatase TiO(2)/perovskite-type porous nanosized LaFeO(3) (T/P-LFO) nanocomposites using a simple wet chemical method. It is clearly demonstrated by means of atmosphere-controlled steady-state surface photovoltage spectroscopy (SPS) respons...

description | In this work we have successfully fabricated nanocrystalline anatase TiO(2)/perovskite-type porous nanosized LaFeO(3) (T/P-LFO) nanocomposites using a simple wet chemical method. It is clearly demonstrated by means of atmosphere-controlled steady-state surface photovoltage spectroscopy (SPS) responses, photoluminescence spectra, and fluorescence spectra related to the formed OH(−) radical amount that the photogenerated charge carriers in the resultant T/P-LFO nanocomposites with a proper mole ratio percentage of TiO(2) display much higher separation in comparison to the P-LFO alone. This is highly responsible for the improved visible-light activities of T/P-LFO nanocomposites for photocatalytic degradation of gas-phase acetaldehyde and liquid-phase phenol. This work will provide a feasible route to synthesize visible-light responsive nano-photocatalysts for efficient solar energy utilization. |
