Article Abstract
Peroxyacetic acid (PAA)-based advanced oxidation processes (AOPs) have emerged as a promising treatment method to decontaminate organic pollutants. This review thoroughly evaluated the use of PAA-based AOPs, including their synthesis techniques, physicochemical features, and reaction pathways with pollutants. It also illustrated two primary channels: free radical pathways and non-radical pathways during the PAA activation processes and introduced various methods for activating PAA, including energy radiation, transition metal catalysis, and carbon catalysis. Additionally, this review comprehensively presented the advancements in research on PAA-based AOPs for wastewater treatment. Furthermore, the influences of key parameters on system performance, such as pH, catalyst loading, PAA dosage, and interfering species, were summarized. By critically evaluating mechanisms, performance, and prospects, this review served as a valuable resource for researchers and practitioners involved in the development and implementation of PAA-based AOPs for sustainable water remediation.

This study attempts to address the technical challenge of poor valence cycling and low activation efficiency of Fe-based catalysts in peracetic acid (PAA)-based advanced oxidation processes (AOPs) for organic micropollutant treatment. The successful synthesis of the Mo doped Fe-based catalyst (FeMo@CN) achieved efficient PAA activation and rapid degradation of organic micropollutants. Mechanistic studies showed that both radical pathway (•OH and CHCOOO•) and non-radical pathway (O) synergistically contributed to bisphenol A (BPA) degradation.

In recent years, extensive attention has been paid to advanced oxidation processes (AOPs) with peracetic acid (PAA), a widely used disinfectant, using transition metal ions for the degradation of organic contaminants within water environments. Mn(II) has been widely used as an effective homogeneous transition metal catalyst for oxidant activation, but it has shown poor performances with PAA. Since the stability of manganese species can be enhanced through the addition of ligands, this study systematically investigated a novel AOP for the oxidation of carbamazepine (CBZ) using an Mn(II)/PAA system with several different ligands added.

Peracetic acid (PAA)-based advanced oxidation processes (AOPs) are appealing for water treatment due to their environmentally benignity and ease of activation. However, the predominant generation of radicals in the existing catalytic systems severely limits their practical water decontamination performance. In this study, we report an Mn-doped Cu(OH)Cl catalyst supported on hexagonal boron nitride (Mn-Cu(OH)Cl@BN), providing dual reaction centers (DRCs) and abundant oxygen vacancies (OVs) to facilitate selective generation of singlet oxygen (O) from PAA activation.

As a pre-oxidation unit, developing non-radical pathway-dominant advanced oxidation processes (AOPs) with remarkably-efficient oxidation, superior environmental robustness, and ecological safety is essential in actual water pollution control. Herein, using CoO as an example, we present an oxygen vacancies (OVs)-mediated peracetic acid (PAA) activation process, thereby predominantly generating singlet oxygen (O) for degrading contaminants. In-situ monitoring of PAA activation by OVs-rich CoO (CoO-OVs) reveals that surface oxygen-containing intermediates (e.

Industrialization has exerted significant adverse effects on water quality, leading to an increasing demand for environmentally friendly and high-efficiency technologies. The traditional Fenton process has been recognized as a viable method for treating challenging industrial wastewater. Recently, peracetic acid (PAA)-based advanced oxidation processes (AOPs) have emerged as a promising Fenton-like technology for efficient wastewater treatment.
