Nanostructured Fe2O3@TiO2 pigments with improved NIR reflectance and photocatalytic ability

Nanostructured Fe2O3/TiO2 composite particles with enhanced NIR reflectance for application to LiDAR detectable cool pigments

“… 16 Fe 2 O 3 pigments show differences in optical properties according to the particle size and shape, 17 and are used in a variety of applications including photocatalysts, ceramics, cosmetics, and industrial paints by improving chromaticity and NIR reflectance. 18–20 Referring to recent literature, 20,21 when SiO 2 or TiO 2 is coated on the surface of Fe 2 O 3 , NIR reflectance can be improved. On the contrary, there is a report that the NIR reflectance of the red pigment is improved by coating Fe 2 O 3 on the surface of the plate-shaped mica particles having excellent NIR reflecting properties, i.e.…”

Hematite Particle Size Effect on Combustion Performance of Fire Extinguishing Composites

“…All that attracted wide investigations for their use in in the field of catalysis, magnetism, electrochemistry, ceramics, pigments, etc. [8][9][10][11][12] Metal oxides have also been extensively used as burn rate catalyst in delay composites, solid rocket propellent composites, plastic bonded explosives, etc. [13][14] Burn rate is a vital factor, which greatly influence the properties (thermal, ballistic, combustion, decomposition) of composites.…”

Effect of calcination temperature and Ti substitution on optical properties of (Fe,Cr)2O3 cool black pigment prepared by spray pyrolysis

“…TiO 2 , ZnO, Fe 2 O 3 and Cr 2 O 3 are representative NIR-reective inorganic pigments. [4][5][6] TiO 2 is white and has excellent reectivity for both visible and NIR light. However, when only TiO 2 pigment is used, it is too bright and has strong glare, which is unpleasant to human eyes.…”

“…Until now, (Fe,Cr) 2 O 3 has been synthesized by a conventional solid-state reaction or a liquid-phase precipitation. 4,10 Spray pyrolysis, one of the gas phase synthesis techniques, has been used to make a variety of functional materials. [11][12][13][14][15][16] In spray pyrolysis, one particle is produced from one droplet containing all precursors.…”
