Diosa Ingeniería Sol gel synthesis Photocatalytic TiO2 nanoparticles Structural and optical properties TiO2 nanoparticles were synthesized using a facile, reproducible, and scalable sol-gel method and their structural and optical properties was studied. XRD ad FTIR was used to identify the phase, crystallite size, and functional groups present in the nanoparticles. The prepared samples crystallize in the anatase structure with a highly crystalline order. TEM/EDX shows that the nanoparticles are pure, spherical, and with an average particle size of 15 ( 2 nm. The optical band gap energy is around 3.69 ± 0.10 eV and exhibits blueshift with respect to the bulk anatase. PL emission is attributed to oxygen vacancies (Vo). All samples were photoactive for MO degradation after 240 min of being irradiated with visible light. 2021 otro 0123-3033 https://www.redalyc.org/articulo.oa?id=291368646014 https://www.redalyc.org/journal/2913/291368646014/ https://www.redalyc.org/journal/2913/291368646014/html/ https://www.redalyc.org/journal/2913/291368646014/291368646014.epub https://www.redalyc.org/journal/2913/291368646014/movil 10.25100/iyc.v23i2.10965 en http://www.redalyc.org/revista.oa?id=2913 Ingeniería y Competitividad application/pdf Universidad del Valle Ingeniería y Competitividad (Colombia) Num.2 Vol.23 |
