Abstract
Multifunctional photocatalytic and thermochromic composites consisting of fluorine-doped vanadium dioxide (F–VO2) and niobium-doped TiO2 (NTO) were prepared by a simple physical mixing. The composites exhibited a higher thermochromic activity and nitrogen oxide (NOx) decomposition activity than that of pristine VO2/NTO. Both VO2 and NTO materials were synthesized using an environmentally friendly soft chemical solvothermal/hydrothermal process, which produced NTO nanoparticles with a controllable morphology and particle size by changing the ratio of ethanol and acetic acid solvent. F–VO2/NTO showed a better multifunctionality of thermochromic and photocatalytic activities than those of VO2/NTO samples. The coexistence coating films showed a better effect on thermochromic and deNOx (NOx reduction) activity than those of double-sided films for F–VO2/NTO samples. The best thermochromic and photocatalytic activities obtained from sample F–VO2/NTO 60 showed the ΔT1500 nm [difference of transmittance (ΔT) at the wavelength of 1500 nm under 25 °C and 95 °C] of up to 29.5% and deNOx activity of up to 40% at λ > 290 nm under mercury lamp irradiation. The use of F–VO2/NTO coexistence coating films showed the appropriateness for multifunctional materials.
