Effects of metal nanoparticles deposition on the photocatalytic oxidation of ammonia in TiO2 aqueous suspensions

Photo-Fenton degradation of ammonia via a manganese–iron double-active component catalyst of graphene–manganese ferrite under visible light

“…TiO 2 has been used to break NAH bonds and explore the mechanism of NH 3 decomposition [12,13]. Some researchers have shown that the photocatalytic technique can destroy NAH bonds completely [14][15][16][17][18][19][20]. However, most photocatalysts developed for this purpose are mainly TiO 2 -based, few other photocatalysts have been explored to degrade NH 3 .…”

Surface reconstruction, oxygen vacancy distribution and photocatalytic activity of hydrogenated titanium oxide thin film

“…Since the discovery of its photoactivity by Fujishima and Honda [1], and owing to its exceptional properties, such as low cost, high stability, high chemical inertness, bio-compatibility, and non-toxicity, TiO 2 has been examined widely as an efficient photocatalyst material for purification of water, degradation of dyes and pesticides, etc [2][3][4]. However, the photocatalytic efficiency of TiO 2 is hampered by several obstacles such as wide band gap and easy recombination of photogenerated electron/hole pairs [5][6][7]. Numerous attempts have been made to overcome these problems including doping by metals or nonmetals [8][9][10][11][12], cocatalyst immobilization [13], and controlled faceting [14].…”

Oxidation of ammonia using PtRh/C electrocatalysts: Fuel cell and electrochemical evaluation

“…Moreover, ammonia is also one of the most concerning industrial wastes because its large-scale production, being the second largest chemical produced all over the world [9,10].…”
