“…For simultaneous detection and removal of phenol from wastewater, Xing et al investigated an innovative three-dimensional (3D) hierarchical ascorbic acid-functionalized nickel manganese (NiMn)–calcined layered double hydroxides (CLDHs)@HNTs–Ag nanomotor (AANiMn–CLDHs@HNTs–Ag). 65 The average length and diameter of the AA–NiMn–CLDHs@HNTs–Ag micro/nanomotor are 970 nm and 200 nm. Autonomous motion, peroxidase-like activity, hierarchical structures, and highly exposed active sites were combined to enable highly sensitive and selective phenol detection as well as rapid phenol removal.…”

“…prepared AA-NiMn-CLDHs@HNTs-Ag nanomotors by assembling AgNPs and NiMn-CLDH nanosheets inside and outside the lumen of natural halloysite nanotubes (HNTs) using a layer-by-layer self-assembly technique, which was able to degrade 95.63% of phenol within 90 min (Xing et al, 2022). Magnetic material Au@Ni/rGO with a size less than 8 nm and core-shell nanostructure was successfully synthesized and exhibited peroxidase-like activity, exhibiting excellent performance in the photodegradation behavior of phenol, 2-chlorophenol and 2-nitrophenol (Darabdhara and Das, 2019).…”

Peroxidase-like based on double transition metals have higher catalytic activity and are considered to have great potential for application in the eld of pollutant degradation. First, in this paper, a novel Fe 0doped three-dimensional porous Fe 0 @FeMn-NC-like peroxidase was synthesized by a simple one-step thermal reduction method. The doping of manganese was able to reduce part of the iron in Fe-Mn binary oxides to Fe 0 at high temperatures. In addition, Fe 0 @FeMn-NC has excellent peroxidase-like mimetic activity, and thus it was used for the rapid degradation of p-chlorophenol (4-CP). During the degradation process, Fe 0 was able to rapidly replenish the constantly depleted Fe 2+ in the reaction system and brought in a large number of additional electrons. The ineffective decomposition of H 2 O 2 due to the use of H 2 O 2 as an electron donor in the reduction reactions from Fe 3+ to Fe 2+ and from Mn 3+ to Mn 2+ was avoided. Finally, based on the experimental results of LC-MS and combined with theoretical calculations, the degradation process of 4-CP was rationally analyzed, in which the intermediates were mainly pchloro-catechol, p-chloro resorcinol and p-benzoquinone. Fe 0 @FeMn-NC nano-enzymes have excellent catalytic activity as well as structural stability, and perform well in the treatment of simulated wastewater containing a variety of phenolic pollutants as well as real chemical wastewater. It provides some insights and methods for the application of peroxidase-like enzymes in the degradation of organic pollutants.
