Anatase TiO2 hierarchical microspheres consisting of truncated nanothorns and their structurally enhanced gas sensing performance

Highly crystalline anatase TiO2 nanocuboids as an efficient photocatalyst for hydrogen generation

“…When compared to the other methods, the hydrothermal method not only enables obtaining materials with a large surface area and high crystallinity but also exibly adjust the parameters to control the particle size and morphology of products. 41 So far, numerous morphologies of TiO 2 nanostructures viz., nanowires, 42 nanotubes 43 nanobelts, 44 nanorods, 45,46 nanosheets, 47 nanoowers, 48,49 hierarchical microspheres 50 have been effectively synthesized by hydrothermal technique. Moreover, many researchers have exploited the synthesized TiO 2 nanostructures for the photocatalytic hydrogen generation.…”

Hierarchical Nanostructures of Titanium Dioxide: Synthesis and Applications

“…Mesoporous nanothorn-like structures are produced as a result of this process [59] shown in Figure 10. These structures are employed for gas sensing application of acetone.…”

Significance of the surface and bulk features of hierarchical TiO2 in their photocatalytic properties

“…The development of this type of semiconductor is necessary because its structure, quality, and morphology define the nanomaterials' applicability resulting in higher efficiency of the desired application [3,4]. The morphology control of nanocrystals entered in the focus of semiconductor-research during the last decade, including improvement of the photocatalytic efficiencies or modulating the gas sensing properties by the means of shape-tailoring [5,6].…”

“…Researchers found that TiO 2 anatase structures with exposed (001) facets showed better reactivity than the thermodynamically stable (101) surface [21,22]. Theoretical calculation suggested that the (001) crystal facets showed much better gas adsorption activity compared to (101) facets [5]. Li H. et al [19] reported a solvothermal method to obtain hierarchical flower-like TiO 2 , where the reaction time, applied temperature and the addition of ethanol played a critical role.…”
