Photocatalytic properties of aqueous systems containing TiO(2) nanoparticles
Original language description
This work describes the aging of aqueous colloidal TiO(2) nanoparticles at different temperatures and pH values. Emphasis was particularly given to the behaviour in the alkaline region, since this has not yet been properly reported. Aging of colloidal TiO(2) suspensions has previously been investigated using spectroscopic methods (band gap energy determination) and a dynamic light scattering method (particle size determination). The photocatalytic activity, representing the most important property of TiO(2) nanoparticles, was determined through the quantum yield of 4-chlorophenol degradation. It was found that the size of acidic colloidal TiO(2) particles depends on the storing temperature; lower temperature leads to a small increase in particle size.The process of aging of TiO(2) nanoparticles consists in slow re-crystallization that leads to slightly larger particles, and it seems that this process is faster at higher temperatures. In alkaline environments it was found that the chan
