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.

“…There are number of analytical methods available for determination of hydrogen peroxide, such as titrimetry [10], fluorescence [11][12][13][14], spectrophotometry [15][16][17][18], chemiluminescence [19][20][21], and electrochemical methods [22][23][24]. Among them, electrochemical method based on various sensing materials is an attractive option due to its high sensitivity and selectivity, low cost, operational simplicity and real-time monitoring.…”

A simple and reliable design of the non-enzymatic sensor capable of instant detection of broad range of hydrogen peroxide (H 2 O 2) concentrations in various water-based matrixes has been presented. Manufacturing of the sensor was based on the manganese dioxide (MnO 2)-nonfunctionalized single walled carbon nanotubes (SWCNTs)-Nafion nanocomposite modified glassy carbon electrode (MnO 2 /SWCNTs-Nf/GCE). The electrochemical behavior of hydrogen peroxide at this sensitive platform was verified by the cyclic voltammetry and amperometry. The obtained results have demonstrated that the modified GCE exhibited an excellent electrocatalytic activity toward hydrogen peroxide. The parameters related to this sensor, such as amount of MnO 2 , applied potential and pH value were optimized to attain a broad working linear range 6 10 0. 3   M, with detection limit of 0.52  10-6 M (17.7 ppb) of detection H 2 O 2. Developed electrode was tested for stability and accuracy measurements in environmental/biological conditions, such as pH and interference of common ions, namely calcium, magnesium, nickel, copper, bicarbonate and citrate, showing an excellent stability and repeatability in tested ranges.

“…But the high cost of the native enzyme has stimulated a search for its alternatives. Some peroxidase mimetics such as hemin, porphyrins, phthalocyanines, and metal nanoparticles have shown a peroxidase-like activity [1][2][3][4][5][6][7][8][9].…”
