“…Huang and co-workers [184] highlighted the complex role of glucose in the Bio-Fenton reaction, reporting that, at a too-high concentration, it could also act as a hydroxyl radical scavenger, inhibiting the oxidation reaction. The optimization of hydrogen peroxide generation could be obtained, therefore, by using specific techniques, which allow for the evaluation of the influence of different variables on the reaction outcomes [185].…”

“…Limited scale-up and techno-economic analysis are available for Bio-Fenton treatments. Enzyme cost and stability could represent critical points for its real applications; however, some studies suggest that GOx production could be cost-effective and scalable [185]. Moreover, as widely described above, the immobilization of glucose oxidase improves its stability towards oxidation and deactivation due to environmental factors and ensures its reusability, making Bio-Fenton suitable for actual wastewater treatment; • Although, to the best of the authors' knowledge, there are no reported pilot or fullscale plants that integrate Bio-Fenton in wastewater treatments, its effectiveness as a pretreatment to be coupled with conventional active sludge was highlighted by Wang et al [189].…”

The use of hydrogen peroxide (produced in situ or ex situ) as the main agent in oxidative processes of environmental pollutant removal is widely studied. The degradation of water pollutants, such as dyes, pharmaceuticals, cosmetics, petroleum derivatives, and even pathogens, has been successfully obtained by different techniques. This review gives an overview of the more recent methods developed to apply oxidative processes mediated by H2O2 and other reactive oxygen species (ROS) in environmental catalysis, with particular attention to the strategies (Fenton-like and Bio-Fenton, photo- and electro-catalysis) and the materials employed. A wide discussion about the characteristics of the materials specifically studied for hydrogen peroxide activation, as well as about their chemical composition and morphology, was carried out. Moreover, recent interesting methods for the generation and use of hydrogen peroxide by enzymes were also presented and their efficiency and applicability compared with the Fenton and electro-Fenton methods discussed above. The use of Bio-Fenton and bi-enzymatic methods for the in situ generation of ROS seems to be attractive and scalable, although not yet applied in full-scale plants. A critical discussion about the feasibility, criticalities, and perspectives of all the methods considered completes this review.
