“…In addition to the scientific findings in developing nanoparticles to degrade organic pollutants [27][28][29][30][31] Therefore, the performance of the synthesized nanocomposite was evaluated in the process of picric acid degradation as an organic pollutant through peroxymonosulfate activation. In comparing this nanocomposite with other nanocomposites [32][33][34][35][36] , we can point out its distinctive features such as easy preparation, short degradation time, structural checking via various analyses, especially XPS and AFM spectrum, high degradation efficiency, excellent performance by few dosages of the nanocomposite in the degradation process, degradation with the easy method without the need to sunlight and radiation, and investigating the removal picric acid as a vital contamination in drug and industries.…”

In recent years, using nanomaterials based on multi-wall carbon nanotubes (MWCNT) through the activation of peroxymonosulfate (PMS) has attracted more attention to the degradation of organic pollutants. This research presented a new route for the synthesis of MWCNT/CoMn2O4 nanocomposite for the degradation of picric acid using advanced oxidation processes (AOPs). Firstly, CoMn2O4 nanoparticles were prepared and then loaded on MWCNT using ultrasonic waves. The results of various analyzes confirmed the successful loading of nanoparticles on carbon nanotubes. As the degradation process proceeds through oxidation processes, the high electronic conductivity of MWCNT and the active sites of Mn and Co in the nanocomposite play an essential role in activating PMS to generate reactive oxygen species (ROS). An investigation of the reaction mechanism in different conditions showed that the highest speed of picric acid decomposition in the presence of nanocomposite (98%) was in 47 min. However, the scavenger test showed that HO· and SO4·− radicals are more important in the degradation process. Meanwhile, the results showed that removing picric acid using MWCNT/CoMn2O4 was more effective than CoMn2O4 alone and confirmed the interaction effect of MWCNT nanotubes with AB2O4 nanocatalyst.

“…Wastewater from the dye industry is considered as one of the most complex organic contaminant mixtures [28] , [29] that can have a significant impact on water bodies, even at low concentrations [30] , [31] . Dyes such as Methylene Blue, Methylene Orange or Rhodamine B (RhB) have become popular degradation targets in piezocatalysis [5] , [6] , [7] due to their toxicity [31] and ability to promote oligotrophic water conditions [30] . In this regard, the vast majority of piezocatalysis research has focused on the development and fabrication of micro- and nano-sized piezocatalysts [7] , [11] , [18] , [27] .…”

“…The activation method of oxidants is crucial for the production of high oxidative ROS [27]. The activation methods generally include physical activation, chemical activation, and catalytic activation, the former of which needs exterior energy (heat, ultrasonic, or ultraviolet) for the generation of radicals, leading to some inevitable disadvantages comprising harsh reaction conditions, a high energy requirement, and complicated operation and equipment [28,29]. The chemical activation method, adopting an alkaline metal, phenol, or quinone as the activator, not only requires a high dosage of these chemicals, but can also produce toxic substances [30,31].…”

The fast rise of organic pollution has posed severe health risks to human beings and toxic issues to ecosystems. Proper disposal toward these organic contaminants is significant to maintain a green and sustainable development. Among various techniques for environmental remediation, advanced oxidation processes (AOPs) can non-selectively oxidize and mineralize organic contaminants into CO2, H2O, and inorganic salts using free radicals that are generated from the activation of oxidants, such as persulfate, H2O2, O2, peracetic acid, periodate, percarbonate, etc., while the activation of oxidants using catalysts via Fenton-type reactions is crucial for the production of reactive oxygen species (ROS), i.e., •OH, •SO4−, •O2−, •O3CCH3, •O2CCH3, •IO3, •CO3−, and 1O2. Nanoscale zero-valent iron (nZVI), with a core of Fe0 that performs a sustained activation effect in AOPs by gradually releasing ferrous ions, has been demonstrated as a cost-effective, high reactivity, easy recovery, easy recycling, and environmentally friendly heterogeneous catalyst of AOPs. The combination of nZVI and AOPs, providing an appropriate way for the complete degradation of organic pollutants via indiscriminate oxidation of ROS, is emerging as an important technique for environmental remediation and has received considerable attention in the last decade. The following review comprises a short survey of the most recent reports in the applications of nZVI participating AOPs, their mechanisms, and future prospects. It contains six sections, an introduction into the theme, applications of persulfate, hydrogen peroxide, oxygen, and other oxidants-based AOPs catalyzed with nZVI, and conclusions about the reported research with perspectives for future developments. Elucidation of the applications and mechanisms of nZVI-based AOPs with various oxidants may not only pave the way to more affordable AOP protocols, but may also promote exploration and fabrication of more effective and sustainable nZVI materials applicable in practical applications.
