N/Fe/Zn co-doped TiO₂ loaded on basalt fiber with enhanced photocatalytic activity for organic pollutant degradation

Abstract

The photocatalytic activity of N/Fe/Zn_TiO2@BF, synthesized by a combined sol–gel calcination method, showed great improvement for the degradation of RhB. The reaction mechanism of N/Fe/Zn_TiO2@BF for the degradation of RhB was proposed.

Heterogeneous Photocatalysis as a Potent Tool for Organic Synthesis: Cross-Dehydrogenative C–C Coupling of N-Heterocycles with Ethers Employing TiO2/N-Hydroxyphthalimide System under Visible Light

“…The modification of heterogeneous photocatalysts, such as TiO 2 , in order to shift their photoactivity spectrum from UV to visible light [ 10 , 34 , 35 , 36 , 37 ] is the key task for expanding the scope of their applications in organic synthesis, increasing selectivity and making the of use cheap and available light sources for catalyst activation possible. At present, the following modification approaches have been proposed: the immobilization of dyes (organic compounds or metal complexes) on the photocatalyst surface [ 34 , 38 , 39 , 40 , 41 ], doping with metal ions or non-metal elements [ 42 , 43 ], semiconductor coupling [ 7 , 44 , 45 , 46 , 47 , 48 , 49 ] and modification with organic molecules bearing hydroxyl or carboxyl groups [ 34 , 50 , 51 , 52 , 53 , 54 , 55 , 56 ], which demonstrate the occurrence of visible light absorption when adsorbed on the surface of a semiconductor.…”
