Ti-containing volcanic ash as photocatalyst for degradation of phenol
Abstract
Photocatalysis application in effluent decontamination is becoming one of the most promising green chemistry technologies. In this paper, natural volcanic ash particles have been characterized and used either as photocatalysts or as a support for a titania-containing photocatalyst. The natural material alone displayed good photocatalyst behaviour as a consequence of the presence of some titanium compounds in its composition. The original ashes were further loaded with TiO2 through
