Photocatalytic Removal Of 2, 4- Dichlorophenoxyacetic Acid And Quinclorac Herbicides By An Immobilized System Of Carbon Coated, Nitrogen Doped And Polyene Sensitized TiO2
An immobilized system of carbon coated, nitrogen doped and polyene sensitized TiO2 (CNTiO2/EP-10h) was fabricated using epoxidized natural rubber (ENR50) and polyvinyl chloride (PVC) as the binders through a dip coating technique. The optimum amount of photocatalyst and PVC binder in the coating for...

| description | An immobilized system of carbon coated, nitrogen doped and polyene sensitized TiO2 (CNTiO2/EP-10h) was fabricated using epoxidized natural rubber (ENR50) and polyvinyl chloride (PVC) as the binders through a dip coating technique. The optimum amount of photocatalyst and PVC binder in the coating formulation were 6 g and 0.8 g, respectively, while 2.29 mg cm-2 was the best amount of photocatalyst composite loading. The photo-etching process for 10 hours (10h) reduced the band gap energy of the photocatalyst from 2.91 to 2.86 eV, creating a highly porous photocatalyst surface as well as oxidizing the PVC binder to be a conjugated polyene that sensitized TiO2. |
