✦ Synopsis

The flame synthesis of titania particles with special properties for the photooxidation of organic contaminants in water is investigated. Powders with high specific surface area (> 100m2/g) and high anatase content were produced in a hydrocarbon flame reactor at various conditions. These powders were used for the photodegradation of phenol in non-aerated aqueous solutions under UV-irradiation.

The reaction followed first order kinetics and the photodestruction rates of these powders were comparable with or better than those of commercially available titania powders.

A novel three-step process is used to fabricate submicron silicon carbide powders in this paper. The commercially available silicon powders and phenolic resin are used as raw materials. In the first step, precursor powders are produced by coating each silicon powder with phenolic resin shell. Then,
