The objective of this work is to investigate the effect of surface modification with H2O2 solution on the properties of boehmite in support of a Fenton-like catalyst. The modified and unmodified boehmite were characterized by BET, scanning electron microscopy, ammonia temperature-programmed desorption, and x-ray powder diffraction. The results show that the BET surface area, pore volume, and surface acidity of the modified boehmite increase. Meanwhile, Fe and/or Cu is/are supported on the modified or unmodified boehmite to degrade the phenol wastewater as evaluated by the chemical oxygen demand (COD) removal by means of advanced oxidation processes. We found that the Fe and/or Cu supported on the modified boehmite exhibit(s) much higher catalytic activity than as supported on the unmodified boehmite, and the COD removal reaches 90% using the Fe-Cu catalyst within 60 min. The results highlight the H2O2-modified version as being an effective and environmentally friendly method for support treatment.
