2022年9月15日 · Low K content in TiO 2 boosted its photocatalytic activity for acetaldehyde oxidation. During NO oxidation NO 3– selectivity was significantly increased as a function of K content. Role of K content was different in different photocatalytic reactions and …

2012年9月1日 · We provide a brief introduction to the current situation in TiO 2 photocatalysis, and describe structurally controlled TiO 2 photocatalysts which can be classified into zero-, one-, two-, and three-dimensional structures. Furthermore, novel applications of TiO 2 surfaces for the fabrication of wettability patterns and for printing are discussed.

2024年9月15日 · Among the catalysts, 0.374% K-TiO 2 annealed at 375 °C exhibited the highest NO removal efficiency. This superior performance can be ascribed to the reduced band gap and increased separation efficiency (or lifetimes) of electron-hole pairs by K. Conversely, its activity towards acetaldehyde oxidation was lower than that of bare TiO 2.

Titanium dioxide (TiO 2) is a naturally occurring oxide of titanium. It possesses a high refractive index, making it an important material in optical coatings and components, especially as a white pigment in paints, cosmetics, and sunscreens due to its UV absorbing properties.

2024年9月11日 · The present work is to investigate K doped TiO 2 nanoparticles successfully synthesised from Solanum torvum leaf extract. The synthesised K/TiO 2 nanoparticles were characterized by Powder X-ray Diffraction, UV–Visible Spectroscopy, Fourier Transform Infrared Spectroscopy, Scanning Electron Microscopy and Energy-dispersive X-ray spectroscopy.

Flower-like rutile TiO2 mesocrystals were fabricated by a K2TiO (C2O4)2-mediated Ti–H2O2 interaction at 80 °C and under atmospheric pressure. Both thin films precipitated on the metallic Ti substrates and powders collected from the solutions were subjected to detailed characterizations of the nanostructures and phot
