Photocatalytic Degradation of Aniline Using TiO2Nanoparticles in a Vertical Circulating Photocatalytic Reactor

Optimization of Photocatalytic Degradation of Phenol Using Simple Photocatalytic Reactor

The phenol photocatalytic degradation was investigated using heterogeneous catalyst Ag-doped ZnO nanowires under UV irradiation. Ag-ZnO nanowires were immobilized on borosilicate glass via a simple hydrothermal technique. Preliminary photodegradation studies were performed with Ag-ZnO nanowires at various concentrations of phenol (10 60 mg/L) at undiluted pH. After determination of the optimal ...

High efficient degradation of Cefixime using UV/TiO2 photocatalytic process: A comparison between photocatalytic and photolytic

Introduction: The existence of pharmaceuticals in aquatic ecosystem, their persistence and possible effects on living organisms and inefficient systems in removal of these compounds from water and wastewater are a growing concern. In this research, the UV/TiO2 photocatalytic degradation of Cefixime was investigated so as to identify if this method was efficient for removal of Cefixime or not. ...

Evaluation of TiO2, ZnO, CuO and Ga2O3 on the Photocatalytic Degradation of Phenol Using an Annular-Flow Photocatalytic Reactor

Even with rigorous environmental regulations, phenol still is a major contaminant. One possible solution is the use of heterogeneous photocatalysis due to low chemical addition, feasibility and reliability to be implanted on cost-effective industrial process. TiO2 is the most employed photocatalyst because of its favorable (photo) chemical properties and ZnO is considered one of the best altern...

Photocatalytic Degradation of Acetaminophen

The photocatalytic degradation of a common analgesic (acetaminophen) with titanium dioxide irradiated with low energy ultraviolet light (365 nm) was studied in order to determine the effect of several parameters such as catalyst’s weight, photochemical effect, and initial concentration. The results indicate that acetaminophen is degraded in the order of 4% by the photochemical effect. The prese...
