Biomass-based activated carbon fiber paper is a promising support for metal or metal oxide owing to its high specific surface area and three-dimensional network. In this work, CuO-loaded phosphorus-doped activated carbon fiber paper (CuO/ACFP) was fabricated by phosphoric acid activation and further copper nitrate calculation. The sisal fiber-based CuO/ACFP was employed as a heterogeneous Fenton-like catalyst for degradation of phenol. The influence of calculation temperature on catalyst properties were also investigated as well as the pH value effect on phenol catalytic reaction. The 100% phenol degradation efficiency was achieved by the CuO/ACFP for activating H2O2, in which CuO/ACFP possessed the specific surface area of 190 m~2g~(-1) and micropores accounted for 80.4% of the total pore volume. The catalytic performance could be well maintained after five times recycle. The high catalytic performance and the great stability were ascribed to its three-dimensional reticulated hollow structure and the synergistic effect between the well-dispersed CuO and the introduction of phosphorus. Moreover, the quenching experiments and electron paramagnetic resonance indicated that the hydroxyl radical generated from H2O2, which was activated via CuO/ACFP, played an important role in phenol degradation. This work proposed a promising heterogeneous catalyst for activating H2O2 to degrade phenolic wastewater.
