Nanoscale anatase TiO2 with dominant {111} facets shows high photocatalytic activity

One-step synthesis of rutile nano-TiO2 with exposed {1 1 1} facets for high photocatalytic activity

“…6B and relative apparent first order rate constants k are listed in Fig. 6C and Table 1 [28]. The apparent first order rate constants k are in the order of RT3 < 6RT3 < 9RT5 < 9RT4 < 9RT3.…”

“…Crystal facets controlling of anatase TiO 2 has attracted a high attention [19,20]. Since anatase TiO 2 with exposed {0 0 1} facets was successfully prepared with the adding of HF [21][22][23], other crystal facets such as {1 0 0} [24][25][26], {111} [27,28] exposed anatase TiO 2 were reported subsequently. As the most stable phase of TiO 2 , rutile has well performance in photocatalytic degradation and water photo-splitting [29][30][31].…”

In-situ synthesis of plasmonic Ag/Ag3PO4 tetrahedron with exposed {111} facets for high visible-light photocatalytic activity and stability

“…Recent studies have demonstrated that photocatalytic properties of photocatalysts can be further enhanced by exposed active facets [22][23][24]. It has been reported that TiO 2 with exposed {111} facets exhibit a higher photocatalytic activity in H 2 evolution than {001}, {100} and {101} planes [25][26][27][28][29]. Recently, efforts have been paid to the exploration of Ag 3 PO 4 with different active facets, such as concave trisoctahedron [30], cube [31], rhombic dodecahedron [32], tetrahedron [33], dendrite [34], tetrapod [35], etc.…”

Atomic layer deposition of TiO2-nanomembrane-based photocatalysts with enhanced performance

“…[1][2][3][4][5][6] Especially, oxides semiconductor such as titanium dioxide (TiO 2 ), zinc oxide (ZnO) and related structures have attracted attention for applications in photocatalysis, gas sensing, and photovoltaic cells. [7][8][9][10][11][12] The enhancement of photocatalytic properties of the TiO 2 -ZnO composite structure, in comparison with TiO 2 oxide has been reported. 8,9,13 It is believed that the coupling of anatase and rutile TiO 2 with ZnO can achieve a more efficient electronhole pair separation under illumination and, consequently, a higher reaction rate.…”
