“…In order to ensure an optimized electron transfer, these proteins are often immobilized on highly conductive materials, both organic and inorganic, with a large surface area [248]. Interesting examples of these materials that also find application in the bio-medical sector are gold nanoparticles [249][250][251], nanometric metal oxides [252,253], metal nanoparticle-MOF [254][255][256][257], carbon nanotube-MOF [258] and metal nanoparticle-polymers [259,260].…”

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.

Owing to the unique properties of 2D graphene derivatives (2D GDs), their composites with other materials possess superior characteristics over other existing materials in the universe. Accordingly, 2D GDs-based composites have emerged as leading materials for substantial advancements of various technological industries such as energy, electronics, sensors, catalysis, environmental remediation, biomedical and structural sectors. Recently, numerous research innovations, have been developed for reliable production of 2D GDs-based composites with high quality, plentiful availability and competitive costs. The overall performance of 2D GDs-based composites is controlled by three main issues. First, the synthesis strategy of GD sheets, which determines the characteristic properties, quantity and cost of the 2D GD product. Second, the surface functionalization of GD sheets, which enhances the compatibility and chemical affinity between GD sheets and other materials within the composites. Finally, the processing method of the composite that strongly affects its microstructure, properties, productivity and cost. This makes such three processes, matters of great concern when designing 2D GDs-based composites for specific application. In this article, the structure, properties, synthesis and surface functionalization of 2D GDs are reviewed. Then, the review article discusses the research developments of 2D GDs-based composites with inorganic materials and polymers, in terms of preparation, properties and applications. Particular focus is placed on Green and/or clean production technologies. The recent research interest in the 2D GDs/multicomponent hybrid composites, with their distinctive multifunctional properties, is highlighted. Also, the new implemented applications of 2D GDs-based composites from 2021, are pointed out, as well as the currently running practical projects, which are proposing innovative futural applications prospects.

“…Noble metals like gold (Au) [ 64 ] and platinum (Pt) [ 65 ], along with metal nanoparticles like silver (Ag) [ 66 ], palladium (Pd) [ 67 ], and copper (Cu) [ 68 ], are also employed. Polymer nanocomposites incorporating nanoparticles or nanotubes contribute to material diversity [ 69 ]. However, Co 3 O 4 emerges as an advantageous choice due to its exceptional catalytic activity, ensuring enhanced electrochemical reactions critical for H 2 O 2 detection.…”

This research investigates the enhancement of barley’s resistance to salt stress by integrating nanoparticles and employing a nanostructured Co3O4 sensor for the electrochemical detection of hydrogen peroxide (H2O2), a crucial indicator of oxidative stress. The novel sensor, featuring petal-shaped Co3O4 nanostructures, exhibits remarkable precision and sensitivity to H2O2 in buffer solution, showcasing notable efficacy in complex analytes like plant juice. The research establishes that the introduction of Fe3O4 nanoparticles significantly improves barley’s ability to withstand salt stress, leading to a reduction in detected H2O2 concentrations, alongside positive impacts on morphological parameters and photosynthesis rates. The developed sensor promises to provide real-time monitoring of barley stress responses, providing valuable information on increasing tolerance to crop stressors.
