The overall objective of this work was to identify and determine the controlling factors of catalytic activity of CeO2 nanoparticles with different properties. Therefore, four kinds of CeO2 nanoparticles are successfully synthesized and used as peroxidase mimics. The results reveal that the catalytic activity is related to specific surface area and surface oxygen (Osur) content. For different CeO2 nanoparticles, specific surface area is the leading factor of catalytic activity. The catalytic activity increases with the increasing specific surface area. If the CeO2 nanoparticles have similar specific surface area, the less Osur contains, the lower catalytic activity will be. Meanwhile, crystallinity is not the influence factor of catalytic activity. Bamboo‐like CeO2 (B‐CeO2) nanoparticles show excellent catalytic activity and the reaction conditions are optimized. Furthermore, the catalytic activity of B‐CeO2 nanoparticles decreases very slightly after 15 cycles of the catalysis experiment. Therefore, B‐CeO2 nanoparticles can serve as effective recyclable peroxidase mimics.

“…MnO 2 was synthesized under the same synthetic conditions and its Michaelis constant was determined under the same reaction conditions. The K m was acquired by applying a reciprocal plot: 1/ V = ( K m / V max ) (1/[ S ]) + 1/ V max , shown in Table S1. The K m value of Fe 3 O 4 @MnO 2 composite material and MnO 2 were calculated to be 0.12 mM and 0.18 mM, respectively.…”

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

In this study, a colorimetric method was developed for rapid and sensitive determination of gallic acid (GA) by using floral‐like magnetic Fe3O4@MnO2 composite material with enhanced oxidase‐like activity. Fe3O4@MnO2 composite material is able to oxidize 3,3′,5,5′‐tetramethylbenzidine (TMB) to a blue product (oxTMB) with apparent color change and absorbance at 652 nm. GA can reduce the oxTMB yielding a fading blue color. Based on these results, a technique is proposed to detect GA quantitatively and qualitatively with UV–vis spectroscopy and bare eyes. A low detection limit of 0.105 μM and a detection range of 0.01 to 15 μM were obtained with UV–vis spectroscopy. This methodology possesses high potential for application in determination of GA.
