Growth of hierarchical TiO2 nanostructures on anatase nanofibers and their application in photocatalytic activity

In Situ Fabrication of Hierarchically Branched TiO2 Nanostructures: Enhanced Performance in Photocatalytic H2 Evolution and Li–Ion Batteries

“…Furthermore, the BJH analysis (Figure b) correspondingly demonstrates that the HBTF was endowed with larger pore volume (1.89 cm 3 g −1 ) compared with OTF (0.144 cm 3 g −1 ), apart from confirming the mesoporous nature of the as‐fabricated samples. The specific surface area of sample HBTF is also much larger than that of the similar TiO 2 branched architecture ( S BET = 20.41 m 2 g −1 ) obtained via epitaxy growth also employed the TiO 2 electrospun nanofibers ( S BET = 19.79 m 2 g −1 ) as substrates . Actually, the surface area of the sample HBTF is also larger than those of a majority of the reported TiO 2 nanostructures with different morphologies (Table S1, Supporting Information).…”

“…[8b,c] (iii) As the secondary structures merely grew on the surface site rather than root into the main body, they might be exfoliated easily from the primary substrates, especially under the ambit conditions, such as vigorous stir and intensive ultrasound. (iv) During the growth processes of epitaxy, the tiny holes on the surface of the trunks were inclined to serve as growth sites to accommodate the crystal seeds, thereby causing porous structure of the trunks being blocked, which might decrease the active sites and counteract the advantages introduced by the secondary structures …”

Is nano ZrO2 a better photocatalyst than nano TiO2 for degradation of plastics?

“…The band gap energy was calculated as 3.0 eV. 34 It is reported in the literature that the anatase phase has a band gap of 3.2 eV. 7,35 The UV visible spectrum of ZrO 2 nanoparticles in Fig.…”

Hydrothermally Synthesized TiO2Nanoparticles as a Cathode Catalyst Material in Lithium-Oxygen Batteries

“…since they can give large surface-to-volume ratio, may shortens Li ion and O 2 gas diffusion length, and easily ensure e -contact point between catalysts and discharge product to facilitate the electrochemical reaction of electrode [17][18][19][20]. However, using a TiO 2 nanoparticles for the catalyst of lithium-oxygen batteries has been rarely reported in the literature even though it has promising attributes and have been widely investigated for the catalysts of various devices owing to its low cost, non-toxicity, eco-friendliness, and natural abundance [21][22][23][24][25].…”
