Article Synopsis
- The paper presents a simple method to synthesize CaFeO catalysts that effectively degrade palm oil mill effluent (POME) under visible light using two different calcination temperatures, producing catalysts identified as CP550 and CP700.
- CP550 was found to be more effective, achieving a 69.0% chemical oxygen demand (COD) removal after 8 hours of irradiation, although this dropped to 61.0% after multiple uses; meanwhile, CP700 exhibited lower efficiency due to changes in its structure from higher calcination temperatures.
- Analysis revealed that CP550's rough surface and higher porosity contributed to its better performance, while it also showed that adding isopropanol significantly reduced its effectiveness,
Palm oil mill effluent (POME) is a serious and expensive environmental problem in Malaysia. In this paper, CaFeO is introduced as a novel photocatalyst for the degradation of POME under visible light irradiation. Two synthesis routes, auto-combustion and co-precipitation, and two calcination temperatures 550 °C and 700 °C were used to produce four CaFeO catalysts AC550, AC700, CP550 and CP700.
