Effect of calcined atmosphere on the photocatalytic activity of P-doped TiO2

Improved visible light photocatalytic activity of fluorine and nitrogen co-doped TiO2 with tunable nanoparticle size

“…A series of nonmetal elements including N [5][6][7][8], F [9][10][11], S [12], C [13,14] and P [15,16] have been explored, which show that these nonmetal dopants are able to expand the light absorption edge of TiO 2 to the region of visible light thus to improve the photocatalytic activity of materials. In particular, fluorine and nitrogen doping are intensively used for the modification of TiO 2 materials due to their marked thermal stability and cost-effectiveness [17,10].…”

N-doped TiO2 Synthesised via Microwave Induced Photocatalytic on RR4 dye Removal under LED Light Irradiation

“…However, metal doped can also act as a recombination center of electron and holes thus, reducing the photocatalytic activity (Larumbe et al 2015;Meng et al 2007). Some of the nonmetal doping TiO 2 have been explored such as nitrogen (Hou et al 2014;Ilinoiu et al 2013;Michael et al 2014), carbon (Park et al 2009;Wu et al 2013), sulphur (Liu & Chen 2008;Rengifo-Herrera et al 2009), boron (Ochiai et al 2010) and phosphorus (Xia et al 2014;Zheng et al 2010). These nonmetal elements exhibit red-shifted absorption edges.…”

Synergistic Effects of Phosphorus and Cobalt Binary Doping on Visible Light Activity of TiO2 by Sol-Gel Method and Evaluation of Photocatalytic Efficiency

“…The binding energies of Ti 2p3/2 and Ti 2p1/2 (Fig. 2b) components of PCT1 catalyst are located at 459.653 eV and 465.218 eV [37] which corresponds to Ti 4+ ion in TiO2 lattice. The doublet peak (Fig.…”
