Copper pillared bentonite catalyst (CuPBC) was developed from ferrioxalate complex and copper pillared bentonite (CuPB). The samples were characterized for physical and chemical properties. The CuPBC degraded 4-nitrophenol (4-NP) in a batch ultra violet and visible light assisted Fenton process with and without pH adjustments. The best experimental condition that achieved total degradation of 100 ppm of 4-NP was 20% excess H2O2, 2.0 g CuPBC at 40 ℃ in 6 min without pH adjustments. The CuPBC reusability study showed marginal drop of 4.4% in efficiency in the 5th round of experiment. These qualities made CuPBC promising for treating 4-NP pollutant.
