Effects of heat treatment scheme on the photocatalytic activity of TiO2 nanotube powders derived by a facile electrochemical process

Enhanced photocatalytic degradation of methylene blue by ZnO-reduced graphene oxide composite synthesized via microwave-assisted reaction

“…Photocatalytic degradation of organic pollutants for water treatment has attracted wide attention due to its effectiveness, easy operation and ideally producing nontoxic end products [1][2][3][4][5][6]. Photocatalysis is normally based on the light absorption of semiconductor oxide photocatalyst, typically ZnO [6] or TiO 2 [5], to excite the electrons from valence band to conduction band and create electron-hole pairs [7].…”

“…Photocatalysis is normally based on the light absorption of semiconductor oxide photocatalyst, typically ZnO [6] or TiO 2 [5], to excite the electrons from valence band to conduction band and create electron-hole pairs [7]. These electrons and holes can migrate and initiate redox reactions with water and oxygen, and then degrade organic molecules absorbed on the surface of the photocatalyst.…”

Preparation of thermally stable anatase TiO2 photocatalyst from TiOF2 precursor and its photocatalytic activity

“…Among various oxide semiconductor photocatalysts, titania has attracted increasing attention due to its biological and chemical inertness, strong photo oxidization power, cost effectiveness, and long-term stability against photo and chemical corrosion [1,[8][9][10][11][12][13][14]. Now many proposed innovative and commercial applications for photocatalytically active stable titania-coated materials such as bathroom tiles, sanitary wares, and self-cleaning glass for the control of organic contaminants require high processing temperatures and hence high-temperature stability [13,14].…”

Effect of Nd2O3 addition on the surface phase of TiO2 and photocatalytic activity studied by UV Raman spectroscopy

“…Recent studies [11][12][13][14][15] suggest that the photocatalytic and photovoltaic properties of TiO 2 nanoparticles with mixed phases are better than pure anatase TiO 2 . The high photocatalytic activity of the mixed phase TiO 2 such as P-25 (20% rutile, 80% anatase) could be attributed to the synergetic effect of the anatase and rutile particles.…”
