“…The unsaturated SO 3 group in PMS exhibits strong electron absorption ability, making the O–O bond in the structure more easily negatively charged, while the oxygen atom near the hydrogen bond is partially positively charged, rendering PMS more conducive to produce oxidative active species (Honarmandrad et al, 2023; Li, Gu, et al, 2022; Su et al, 2022). Currently, a variety of methods have been performed for the activation of PMS including ultraviolet (UV) light activation, thermal activation, transition metals activation, alkali activation, ultrasonic (US) activation, and other activation methods (Du et al, 2022; M. J. Huang et al, 2022; Li et al, 2021; Wen et al, 2023; Xu et al, 2019). However, the aforementioned activation methods still have some limitations.…”

In recent years, the synergistic degradation of water pollutants through advanced oxidation technology has emerged as a prominent research area due to its integration of various advanced oxidation technologies. The combined utilization of peroxymonosulfate (PMS) activation technology and photocatalysis demonstrates mild and nontoxic characteristics, enabling the degradation of water pollutants across a wide pH range. Moreover, this approach reduces the efficiency of electron hole recombination, broadens the catalyst's light response range, facilitates electron transfer of PMS, and ultimately improves its photocatalytic performance. The paper reviews the current research status of photocatalytic technology and PMS activation technology, respectively, while highlighting the advancements achieved through the integration of photocatalytic synergetic PMS activation technology for water pollutant degradation. Furthermore, this review delves into the mechanisms involving both free radicals and non‐radicals in the reaction process, and presents a promising prospect for future development in water treatment technology.
