Fabrication of CeVO4 as nanozyme for facile colorimetric discrimination of hydroquinone from resorcinol and catechol

Electrodeposition-Assisted Rapid Preparation of Pt Nanocluster/3D Graphene Hybrid Nanozymes with Outstanding Multiple Oxidase-Like Activity for Distinguishing Colorimetric Determination of Dihydroxybenzene Isomers

“…Nonetheless, it is difficult to perform colorimetric analysis of CC and HQ using polyphenol oxidase as the catalyst, due to the fatal defects of natural enzymes, for instance, the expensive purification needed and susceptibility to denaturation. Significantly, it has been reported that nanozymes with oxidase-like , or peroxidase-like , activity can be used to selectively detect HQ. Also, the oxidase activity of nanozymes can be used for the selective detection of CC .…”

Fabrication of highly active phosphatase-like fluorescent cerium-doped carbon dots for in situ monitoring the hydrolysis of phosphate diesters

“…Besides, the peak positions of the Ce 3d orbitals and the binding energy difference (DE) between these two components were approximate, indicative of an identical 3+ valence state of Ce. 52,53 In addition, the FTIR and XPS show that there are rich oxygen-containing groups and amino groups on the surface of the CeCDs, indicative of a good hydrophilicity. [54][55][56] This facilitates catalytic hydrolysis of BNPP.…”

Colorimetric detection of gallic acid based on the enhanced oxidase‐like activity of floral‐like magnetic Fe3O4@MnO2

“…These results indicated that TMB-Fe 3 O 4 @MnO 2 composite material system can be used for detection of GA. According to a previous report, [27] hydroquinone as a powerful antiradical and redactor phenolic compound can restore TMB cation radical to their original colorless TMB molecules by the hydrogen donation process. As a similar substance, GA may have the same reduction mechanism, reducing oxTMB to TMB.…”
