Resuscitation of nano-TiO2 photocatalyst by the means of soft-mechanochemical ion exchange method
Ion exchange resin mixed bed was used to filtrate suspensions of nano-TiO2 and methyl-orange after photocatalyzing.Nano-TiO2 photocatalyst and soluble carboxyl titanium was gathered.Then lon exchange resin and photocatalyst and water were mixed round by means of airflow.lon exchange reaction of ion clinging to surface of photocatalyst and counterion on resin were promoted.Middle products ion and inorganic ion were transfered into resin phase.Activity of nano-TiO2 photocatalyst can be resuscitated and reused.
