Abstract

GO-PdNi composite nanozyme has been achieved in this work, which possessed the oxidase catalytic activity. This study shows that the molar mass ratio of Pd and Ni can regulate the catalytic activity of GO-PdNi composites. When the molar mass ratio of the two elements is 1:1, the catalytic activity is better. In addition, temperature, pH, ABTS and nanozyme concentration are also important factors affecting the catalytic activity of nanozymes. Based on the characteristics of the oxidase-PdNi-like characteristic and color detection method, we have designed a method with good selectivity and sensitivity to detect ascorbic acid (AA) in fruit juice. Through the analysis of the experimental results, we obtained the scope of AA detection and linear detection range of 0.2mM and 0.200 ~ 1.296mM, respectively. GO-PdNi has good catalytic performance and is expected to be widely used in the field of food safety.
