“…CSAC is a commonly used catalyst due to its large surface area and porosity [19]. For example, Li et al synthesized CuFe 2 O 4 @CSAC for the degradation of tetrabromobisphenol A (TBBPA) and demonstrated that the surface active sites are the key factors affecting the degradation performance [20]. Pang et al prepared coconut shell composites with high photocatalytic properties for methyl orange [21]; the metal oxide particles were uniformly loaded onto the CSAC, which improved the thermal stability and specific surface area of the material.…”

Energy utilization in wastewater degradation has important implications for sustainability; however, efficient multiphase Fenton-like catalysts are still needed. In this study, a heterogeneous Fe2O3/coconut shell activated carbon (CSAC) Fenton-like catalyst was prepared and evaluated with respect to degradation performance and exothermic reaction for the treatment of organic wastewater. Fe2O3@CSAC retained the porous morphology of CSAS, and Fe2O3 was uniformly loaded on the surface of CSAS. In the reaction system, the degradation rate of wastewater was higher and a large amount of heat was released; therefore, it could be applied to the energy recovery from wastewater source heat pump technology. The degradation rate of 300 mL of o-phenylenediamine solution with a concentration of 0.04 mol·L−1 was 89.0% under 0.25 mol·L−1 H2O2, 532 g·L−1 Fe2O3@CSAC, pH 7.1, and an initial reaction temperature of 30 °C, elevated to 7.9 °C. These findings clearly demonstrate the degradation performance and exothermic laws of the Fe2O3@CSAC/H2O2 multiphase Fenton-like system.
