“…Apart from loading transitional metals, CeO 2 , ,− LaCoO 3 perovskites, and MgO have been loaded on the nanocarbons and employed for catalytic ozonation for pollutant removal. The formation of Me–O–C bonds enhanced the electron transfer between the metal cation and the electron-rich π system of the carbon basal plane.…”

Catalytic ozonation relies on the direct oxidation by ozone (O3) and indirect oxidation by reactive oxygen species (ROS) produced from activated ozone molecules, and the technique has been recognized as one of the most promising remediation technologies in water decontamination. Functional nanocarbon materials have been extensively exploited as heterogeneous catalysts to drive catalytic ozonation because of the environmental-benign process, easy applicability, and high efficiency. Nevertheless, the bottlenecks in the processes are the economical production of high-performance and robust carbocatalysts and the debatable oxidation regimes. Different active sites have been suggested in engineered nanocarbons, and the corresponding mechanisms of the carbocatalytic ozonation are ambiguous including the evolution of various ROS, occurrence of radical and nonradical reaction pathways, selectivity toward organics, and tunable oxidation capacity. In this Review, we will showcase the roadmap of the development of reaction-oriented carbocatalysts and clarify the arguments in the mechanisms of the intrinsic active sites, identification of ROS, reaction intermediates, and oxidation pathways in carbocatalytic ozonation. We will provide critical comments and innovative strategies on the mechanistic investigations in carbon-based ozonation from the molecular level (electronic structures) to macroscale (kinetics), by deliberate radical screening/capture techniques, advanced characterizations and in situ analysis, and theoretical computations. More importantly, the critical issues and future directions will be proposed in the rational material/system design, mechanistic exploration, and the implementation of this powerful technology in catalytic oxidation and real wastewater treatment.

“…Nevertheless, a major limitation of the isothiazolin-3-one compounds makes an allergic action against the skin (skin inflammation) due to the leaching of its components into the environment. Moreover, the presence of the small amount of isothiazolin-3-one component produces momentous antagonistic effects on human health as confirmed by epidemiological investigation (Bollmann et al, 2017;Kandavelu et al, 2004Kandavelu et al, , 2016Rastogi, 2000;Ye et al, 2020). Connor et al examined that CMI is highly mutagenic (Connor et al, 1996), Pelletier et al proved that CMI produced adverse effects on rat's liver (Pelletier et al, 2014), and Poon et al reported that it has produced some respiratory effects in humans (Poon et al, 2011).…”

“…The authors reported that the catalytic action with active TiO 2 and ZnO exhibited significant degradation, whereas paint-grade (inactive) TiO 2 did not exhibit any degradation effect (Kandavelu et al, 2004). Ye et al investigated the decomposition of isothiazolin-3-one via the graphene-assisted ozonation technique (Ye et al, 2020) and Bollmann et al also studied the decomposition of isothiazolin-3-one via the photodegradation method (Bollmann et al, 2017). Recently, thermally nonequilibrium plasma jet treatment has gained significant consideration to degrade the contaminants in effluents without the need for external oxidants, adjustment of pH, and increase of temperature (Hijosa-Valsero et al, 2013).…”

Degradation of residuals of chemical compounds after use has attracted the attention of environmental scientists. In this work, the degradation of such a toxic biocide compound of isothiazolin-3-one from an aqueous solution using a novel multi-pin thermally nonequilibrium atmospheric pressure plasma reactor is reported. This investigation examined the impacts of different operating conditions on the decomposition of isothiazolin-3-one. Subsequently, the reactive excited plasma species formed and participated during the degradation processes were examined by optical emission spectrometer (OES), chemical dosimetry using terephthalic acid (TA), and spectroscopic determination involving potassium titanium (IV) oxalate. The efficiency of degradation of the plasma-treated isothiazolin-3-one from an aqueous solution was examined by UV-Vis spectrometry. The mineralization of isothiazolin-3-one was further examined by high-performance liquid chromatography (HPLC), determining conductivity, total organic carbon (TOC), and pH of the isothiazolin-3-one aqueous solution. Finally, nontoxicity of the plasma-treated isothiazolin-3-one solution was investigated by seed sprouting and germination tests using Vigna radiata L. Wildzek (Mung bean). The experimental results exhibit that a higher degradation percentage of 96.01% was attained for the isothiazolin-3-one treated at a longer treatment time and higher potential of 25 min and 31 kV, respectively. This may be attributed to the formation of various reactive oxygen and nitrogen species (RONS) as confirmed by OES and other spectroscopic analyses. The value of pH and TOC is found to be decreased, whereas the value of electrical conductivity of the isothiazolin-3-one aqueous solution is increased linearly with an increase in treatment time and applied voltage. This indicates the degradation of isothiazolin-3-one molecules and the formation of various ionic species in the solution. The toxicity investigation reveals that the plasma-treated isothiazolin-3-one aqueous solution is nontoxic in nature and useful for sprouting and germination of the Mung bean seeds compared with the untreated one. Overall, it can be concluded that the plasma-assisted process is ideally needed in various food, pharmaceutical, and textile industries as a highly efficient treatment of wastewater.
