Abstract

L'invention concerne un procédé servant à produire un corps de photocatalyseur poreux, consistant au moins à préparer un support en verre de silice poreux ayant des pores communicants et effectuer un traitement servant à former sur la surface du support en verre de silice poreux un revêtement de matière de photocatalyseur. En outre, l'invention concerne un corps de photocatalyseur poreux comprenant au moins un support en verre de silice poreux ayant des pores communicants et, superposé sur la surface du support en verre de silice poreux, un revêtement de matière de photocatalyseur. Encore en outre, l'invention concerne un appareil de purification comprenant au moins un réacteur, le corps de photocatalyseur poreux contenu dans le réacteur et une lampe à rayons ultraviolets, de façon à faire passer un objet à traiter dans le corps de photocatalyseur poreux tout en irradiant le corps de photocatalyseur poreux au moyen de la lampe à rayons ultraviolets pour permettre de cette manière la purification de l'objet à traiter par action photocatalytique. Par conséquent, l'invention concerne un corps de photocatalyseur non seulement ayant une stabilité chimique et une résistance mécanique élevées mais également capable d'exercer efficacement une action photocatalytique. En outre, l'invention concerne un procédé servant à produire le corps de photocatalyseur et un appareil de purification utilisant le corps de photocatalyseur.
