Evaluation of the Photocatalytic Degradation of Pre-Treated Palm Oil Mill Effluent (POME) Over Pt-Loaded Titania

This paper reports the photocatalytic degradation of pre-treated palm oil mill effluent (POME) over a Pt-doped titania photocatalyst. Pt loading on the titania was varied from 0.25 to 1.0 wt% via alcohol reduction of chloroplatinic acid (H2PtCl6). XRD characterization of the photocatalysts showed th...
