New insights into the relationship between structure and photocatalytic properties of TiO₂ catalysts

Abstract

Bi-crystalline nanofibres containing 93.2% anatase and 6.8% brookite showed the highest photocatalytic activity among a series of TiO2 photocatalysts because of their ability to generate high photocurrents and to maintain a stable photoresponse.

Improving the stability of titania nanosheets by functionalization with polyelectrolytes

“…Over the past decades, titania has been widely used in various applications, e.g., in electrochemistry, [1][2][3][4][5] (photo)catalysis, [6][7][8][9][10][11][12][13][14] biomedical processes, [15][16][17][18] development of paints 19,20 and water treatment. [21][22][23] Depending on the synthesis conditions, titania and its composites of various shapes and compositions have been obtained.…”

Hydrothermal Synthesis and Photocatalytic Property of β-Ga2O3 Nanorods

“…In the one-dimensional (1D) morphology, the generation of electron charge carriers is higher along the elongated nanostructures and gives rise to fast transport of charge carriers, due to the hampering of recombination of charge carriers. Hence, 1D nanostructures are gaining more importance for their use in different applications as seen by latest reports [ 9 , 10 ]. For example, Liu et al studied the morphology-dependent photocatalytic properties of bare zinc oxide nanocrystals [ 11 ], which indicated that the rod-shaped ZnO nanostructures have higher photocatalytic activity than the multi-layer disks or truncated hexagonal cones.…”

Effect of Ionic Compounds of Different Valences on the Stability of Titanium Oxide Colloids

“…Biocompatibility is a key property in bioapplications, including delivery of bioactive molecules [6,7], tissue engineering [8], development of biosensors [9], biomimetic [10] and antibacterial materials [11]. Since the discovery of the photoelectric effect in titania [12], enormous effort has been made to develop photocatalytic systems composed of titanium oxide nanostructures or their composites [13][14][15][16][17]. It was also discovered that the shape [18] of the titania particles and the ionic environment [19] influences the photocatalytic activity.…”
