“…Jiangfei Cao and co-workers studied the catalytic degradation reaction of amido black 10B (AB-10B) dye using L-cys-CuNCs supported on red globe flower carbon. 424 Unlike control catalysts (carbon and cluster alone), up to 98% degradation efficiency was reached when the Fenton-like CuNCs/C-H2O2 system was used as catalyst. Several intermediates were confirmed by LC-MS analysis for the degradation reaction of AB-10B dye.…”

Since the ferromagnetic (Fe3O4) nanoparticles were firstly reported to exert enzyme-like activity in 2007, extensive research progress in nanozymes has been made with deep investigation of diverse nanozymes and rapid development of related nanotechnologies. As promising alternatives for natural enzymes, nanozymes have broadened the way toward clinical medicine, food safety, environmental monitoring, and chemical production. The past decade has witnessed the rapid development of metal- and metal oxide-based nanozymes owing to their remarkable physicochemical properties in parallel with low cost, high stability, and easy storage. It is widely known that the deep study of catalytic activities and mechanism sheds significant influence on the applications of nanozymes. This review digs into the characteristics and intrinsic properties of metal- and metal oxide-based nanozymes, especially emphasizing their catalytic mechanism and recent applications in biological analysis, relieving inflammation, antibacterial, and cancer therapy. We also conclude the present challenges and provide insights into the future research of nanozymes constituted of metal and metal oxide nanomaterials.

“…Moreover, even if a strict comparison is difficult because of the numerous parameters involved in this degradation reaction (specific experimental parameters and mechanism), the efficiency of HPICs-Fe competes well with other reported systems involving different mechanisms: Fenton, photo-Fenton, electro-Fenton... (see Table S1). , …”

Iron ions, as traditional high-efficiency Fenton reaction catalysts, react with hydrogen peroxide to generate hydroxyl radicals, thereby degrading organic pollutants in wastewater. However, in aqueous solutions, iron ions have a poor chemical stability and are therefore difficult to recover from the reaction medium. We propose that their complexation with double-hydrophilic block copolymers can lead to the formation of nanocatalysts with improved chemical and colloidal stability. Iron ions were added at different molar ratios to a solution of a double-hydrophilic block copolymer, that is, poly(ethylene oxide)-block-poly(acrylic acid) to lead to the formation of colloidal structures. Spontaneous formation of highly monodisperse micelles with a hydrodynamic diameter around 25 nm occurs when the charge ratio between the positive iron ions and the negative PAA polyanions is close to one. By combining several techniques, a precise description of the core–shell architecture was achieved. These structures are chemically stable in the pH range of 3–7 and have been successfully used as photo-Fenton catalysts through the degradation of naphthol blue black. Compared to the traditional homogeneous Fenton reaction, these colloidal structures have improved chemical and colloidal stabilities as well as a higher recyclability.
