2019年8月5日 · Mesoporous TiO 2 nanotubes (m-TiO 2 -NTs) were successfully synthesized by a morphology-controlled dual-template method. The m-TiO 2 -NTs exhibited superior photocatalytic activity due to the unique multiscale channel structure. The unique tubular structure permits greater mass transfer and entry of light into the tube.

Nanostructured photoanodes were prepared via a novel combination of titanium dioxide (TiO2) nanoparticles and mesoporous carbon (C). Four different photoanodes were synthesized by sol–gel spin...

Light-harvesting of titanium oxide (TiO2) was enhanced by copper (Cu) doping, and its performance was evaluated by gabapentin (GBP) degradation under UVA-LED irradiation. The morphology and...

High-purity anatase TiO 2 nanoparticles were prepared using an improved sol-hydrothermal method. The as-prepared sample was characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), Brunauer-Emmett-Teller …

We proposed a convenient LED reactor that focused light in the range of 350–450 nm, allowing us to effectively use photo-oxidative properties of TiO2–Pt materials in the process of removing...

2017年1月1日 · BET measurement indicated that high surface areas are attainable for core-shell structures addition into TiO2 nanoparticles. TiO2/TiO2@SiO2 core-shell structure has 161.100 m2/g and 0.311 cc/g of surface area and pore volume, respectively. Whereas, TiO2/SiO2@TiO2 core-shell structure has surface area of 140.200 m2/g and pore volume of 0.292 cc/g.

因此，这项工作证明了晶体结构、BET 表面积、表面电荷、zeta 电位 (ζ) 和金属负载量对所制备的钛酸钠纳米管 (TNT) 和二氧化钛纳米棒 (TNR) 的光催化活性的影响。

2021年11月1日 · Comparison of different measurands by using SAXS/BET and SEM analysis for different TiO 2 nanoparticles families to achieve to a dimensional parameter. Highlighting the influence of polydispersity in shape, interactions and impurities, that can affect the results on …

P25纳米二氧化钛（P25 TiO2）为白色粉末状，是采用气相法生产工艺经四氯化钛氢火焰燃烧法制得的混晶型高分散纳米二氧化钛，其锐钛矿与金红石的重量比约为80:20，基本颗粒平均粒径约为21nm，比表面积（BET法）为50±15㎡/g，PH值在4%分散体系中约为3.4-4.5，纳米二氧化钛含量基于灼烧后的物料≥99.5%。 由于两种晶型纳米二氧化钛混杂，增大了纳米二氧化钛晶格内的缺陷密度，使得载流子的浓度增加，电子（e-）和空穴（h+）的数量也随之增加。 因此，P25纳米 …
