  • Highlights: ► Novel synthesis of C-N co-doped TiO{sub 2}. ► Self-assembly of C-N co-doped TiO{sub 2} nanorods by nanoparticles. ► Excellent photocatalytic efficiency. -- Abstract: The C-N co-doped TiO{sub 2} nanorods were synthesized by the vapor transport method of water molecules, and urea was used as the carbon and nitrogen source. The samples were characterized by X-ray diffraction and photoelectron spectroscopy analysis. The scanning electron microscope images showed that as-prepared TiO{sub 2} powders were nanorods, which were formed by the stacking of nanoparticles with a uniform size around 40 nm. The degradation of methylene blue with the prepared nanorods demonstratedmore » the photocatalytic activities of TiO{sub 2} under visible light are improved by doping with C and N elements. The main reasons were discussed: doping with C and N elements could enhance the corresponding visible-light absorption of TiO{sub 2}. On the other hand, doping C and N could create more oxygen vacancies in the TiO{sub 2} crystals, which could capture the photogenerated electrons more effectively. Thus, more photogenerated holes could be left to improve the photocatalytic activity of TiO{sub 2}.« less
  • Ti{sup 3+} self-doped yolk–shell structure titanium oxide nanoparticle aggregates are fabricated through an environmental template-free route and the reduction reaction at low temperature subsequently. After the Ti{sup 3+} doping, the reduced TiO{sub 2} sample exhibits a wide visible-light absorption ranged from 400 nm to 800 nm. The intrinsic hollow core–shell microstructure can make multiple reflections of light within the chamber, and thus results in more efficient use of the light source compared with solid structure. Besides, the large surface area can render the sample with a high activity. Therefore, Ti{sup 3+} self-doped yolk–shell structure titanium oxide exhibits a superior photocatalyticmore » activity under visible light. This strategy is simple, cheap and mass-productive, which may shed light on a new avenue for large scale production of self-doped yolk–shell structural nano functional materials for catalyst, sensors, energy storage and other new applications. - Graphical abstract: A facile generic strategy is employed to prepare Ti{sup 3+} self-doped yolk–shell structure titanium oxide nanoparticle aggregates with the superior photocatalytic activity under visible light. - Highlights: • Yolk–shell TiO{sub 2} mesospheres are synthesized by solvothermal alcoholysis. • Ti{sup 3+} self-doped yolk–shell structure titanium oxide is obtained at low temperature. • It exhibits a remarkable photocatalytic activity.« less
  • The layered compound of lead bismuth oxybromide PbBiO{sub 2}Br, prepared by conventional solid-state reaction method, has an optical band gap of 2.3 eV, and possesses a good visible-light-response ability. The references, PbBi{sub 2}Nb{sub 2}O{sub 9}, TiO{sub 2-x}N{sub x}, BiOBr and BiOI{sub 0.8}Cl{sub 0.2}, which are excellent visible-light-response photocatalysts, were applied to comparatively understand the activity of PbBiO{sub 2}Br. Degradation of methyl orange and methylene blue was used to evaluate photocatalytic activity. The results show that PbBiO{sub 2}Br is more photocatalytically active than PbBi{sub 2}Nb{sub 2}O{sub 9}, TiO{sub 2-x}N{sub x} and BiOBr under visible light. - Graphical abstract: The as-prepared layeredmore » PbBiO{sub 2}Br with an optical band gap of 2.3 eV possesses a fair visible-light-response ability.

  • Visible-light-responsive composite photocatalysts SnS{sub 2}/TiO{sub 2} and SnS/TiO{sub 2} with different mass ratios were prepared by in-situ synthesis technology in solution with commercial TiO{sub 2}. The junction-based materials SnS{sub x} (x=1, 2)/TiO{sub 2} were found to have high visible-light photocatalytic performance and possess much better activity than the single-phase SnS{sub x} or TiO{sub 2}. The greatly enhanced photocatalytic activity of the SnS{sub x}/TiO{sub 2} composites was mainly attributed to the matching band potentials and efficient charge transfer and separation at the tight-bonding interface between SnS{sub x} and TiO{sub 2}. The fact was confirmed by the comparison of photocatalytic activities ofmore » the SnS{sub 2}/TiO{sub 2} samples prepared by physical mixing method and in-situ synthesis technique. - Graphical Abstract: Visible-light-responsive composite photocatalysts SnS{sub 2}/TiO{sub 2} and SnS/TiO{sub 2} with different mass ratios were prepared by in-situ synthesis technology in solution with commercial TiO{sub 2}.
