Revealing the intrinsic peroxidase-like catalytic mechanism of O-doped CoS₂ nanoparticles

Abstract

CoS2 nanoparticles (NPs) have shown promise as potential peroxidase (POD)-like catalysts, but the catalytic molecular mechanisms are largely unknown. Moreover, no study has adequately explored the influence of O-doping induced...

Nanozymes: powerful catalytic materials for environmental pollutant detection and degradation

“…On the one hand, many materials with peroxidase-like catalytic features have been utilized to fabricate Fenton-like systems to degrade these dyes. 44,[198][199][200][201][202][203][204][205][206][207][208][209][210][211][212][213][214][215] For example, Lin's group presented a strategy to construct graphene-gold nanoparticles (graphene/Au-NPs) through a one-step hydrothermal procedure, which acted as an effective scavenger for dyes with the synergetic impact of degradation and adsorption. 200 When different contents of the graphene/ Au-NPs material and H 2 O 2 (300 mM) were introduced to 10 μg mL −1 dye solutions, the remained dye levels were assessed by recording the supernatant's absorbance after removing graphene/Au-NPs.…”
