Catalytic ozonation of naproxen and carbamazepine on titanium dioxide

Degradation of ortho-toluidine from aqueous solution by the TiO2/O3 process

“…The point of zero charge (PZC) of TiO 2 was reported as 6.6 [23] and this factor affected the absorption of the pollutant on the catalyst and was determined by potentiometric titration as explained by Halter [24]. Organic pollutants in neutral state may be adsorbed on the surface of the catalyst if the surface is not charged near the PZC of the catalyst [25].…”

Degradation of the ammonia wastewater in aqueous medium with ozone in combination with mesoporous TiO2 catalytic

“…Many scholars as a separate catalyst or as a carrier research. At present research TiO2nanomaterials are mostly used as a photocatalyst, and TiO2nanomaterials Research ozone catalyst is small, but there are many researchers found that TiO2is a good ozone catalyst [7,8] photocatalyst, researchers have identified the morphology of the catalyst and its catalytic properties of crystal type has a significant impact [9], it is necessary to study the ozone TiO2as a catalyst morphology and crystalline form of the catalytic activity influences. Taking hydrothermal synthesis of different morphologies and Preparation of NanoTiO2crystal phase, select the ammonium chloride wastewater ammonia concentration as a regulator, investigate mesoporous TiO2catalyst on the catalytic properties of ammonia wastewater ozone degradation process, and the catalyst itself performance the study.…”

Catalytic Ozonation of Phenol in Aqueous Solution by Co3O4Nanoparticles

“…3,4 Nanomaterials, which can exhibit unusual chemical and physical properties, are novel and promising heterogeneous ozonation catalysts in environment research. [5][6][7][8][9][10][11] For instance, Jung and co-workers investigated the catalytic ozonation properties of many nanomaterials (including commercial ZnO, biotic and abiotic prepared iron oxide, biogenic magnetite) and found that nano-catalysts are potentially highly efficient catalysts due to their high surface area and well dispersivity. [5][6][7] As an important functional material, Co3O4 has been widely studied as heterogeneous catalysts, anode materials in Li ion rechargeable batteries, solid-state sensors, electrochemical devices etc.…”
