	abstract = {To improve the efficiency of TiO\&lt;sub\&gt;2\&lt;/sub\&gt; as a photocatalyst for contaminant degradation, a novel nanocomposite catalyst of (N, Fe) modified TiO\&lt;sub\&gt;2\&lt;/sub\&gt; nanoparticles loaded on bentonite (B-N/Fe-TiO\&lt;sub\&gt;2\&lt;/sub\&gt;) was successfully prepared for the first time by sol-gel method. The synthesized B-N/Fe-TiO\&lt;sub\&gt;2\&lt;/sub\&gt; catalyst composites were characterized by multiple techniques, including scanning electron microscope (SEM), energy dispersive spectrometry (EDS), X-ray diffraction (XRD), Fourier transform infrared spectra (FT-IR), X-ray fluorescence (XRF), nitrogen adsorption/desorption, UV-Vis diffuse reflectance spectra (DRS), and electron paramagnetic resonance (EPR). The results showed that bentonite significantly enhanced the dispersion of TiO\&lt;sub\&gt;2\&lt;/sub\&gt; nanoparticles and increased the specific surface area of the catalysts. Compared with nondoped TiO\&lt;sub\&gt;2\&lt;/sub\&gt;, single element doped TiO\&lt;sub\&gt;2\&lt;/sub\&gt;, or unloaded TiO\&lt;sub\&gt;2\&lt;/sub\&gt; nanoparticles, B-N/Fe-TiO\&lt;sub\&gt;2\&lt;/sub\&gt; had the highest absorption in UV-visible region. The photocatalytic activity of B-N/Fe-TiO\&lt;sub\&gt;2\&lt;/sub\&gt; was also the highest, based on the degradation of methyl blue (MB) at room temperature under UV and visible light irradiation. In particular, the synthesized B-N/Fe-TiO\&lt;sub\&gt;2\&lt;/sub\&gt; showed much greater photocatalytic efficiency than N/Fe-TiO\&lt;sub\&gt;2\&lt;/sub\&gt; under visible light, the newly synthesized B-N/Fe-TiO\&lt;sub\&gt;2\&lt;/sub\&gt; is going to significantly increase the photocatalytic efficiency of the catalyst using sun light.},
