Nanoparticulate Ru on morphology-manipulated and Ti3+ defect-riched TiO2 nanosheets for benzene semi-hydrogenation

Efficient hydrodeoxygenation of guaiacol to phenol over Ru/Ti–SiO2 catalysts: the significance of defect-rich TiOx species

“…Ru/TiO 2 and Ru/SiO 2 showed a marginal EPR signal; in contrast, two Ti-modified catalysts (Ru/36.2Ti-SiO 2 and Ru/42.0Ti-SiO 2 ) showed a signal of Ti 3+ at a g value of 1.99. 37,[41][42][43] It is known that the defects such as oxygen vacancies and coordinately unsaturated metal cations are critical for C-O bond hydrogenolysis. 44,45 Hence, the TiO x species was expected to promote the deoxygenation reaction.…”

Photodegradation of 2,4-D (dichlorophenoxyacetic acid) with Rh/TiO2; comparative study with other noble metals (Ru, Pt, and Au)

“… 58 Therefore, a reduction of the surface is essential to ensure good photoactivity in the degradation of pollutants. In this sense, it has been reported the importance of interaction that takes place between the metal Rh, 48 Ru, 74 Pt (ref. 75 ) and Au (ref.…”

BiOCl-Fe2O3@TiO2 Mesoporous Composite for Photoelectrochemical Synthesis of Ammonia

“…此外, 将 TiO 2 与其他层 状结构接触, 也能改善材料的可见光吸收能力. 在众多 层状材料中, 二维 BiOX (X＝Cl、Br、I, 带隙 2.8～3.3 eV)是近年来研究较热的光催化材料, 像 BiOCl [26] 、 BiOCl/Bi 12 O 17 Cl 2 [27] 、BiOBr [28] 都具有良好的光催化活性, [29] . 图 2C 中 Fe 的价态较为复杂, 其卫星峰 在 718.8 eV [30] , FT 在 Fe 2p 轨道中的特征峰的位置分别 为 710.8 和 725.1 eV.…”
