摘要：

The urchin-like trimetallic nanozyme Pd-Pt-Ir was firstly prepared through atomic replication. Due to the high affinity to H2O2, the activity of Pd-Pt-Ir is higher than that of Pd-Pt. Based on this concept, Pd-Pt-Ir was applied for the detection of ascorbic acid and hydrogen peroxide. The linear range of ascorbic acid and hydrogen peroxide were 25–800 μM and 3.9–62.5 mM, respectively, and the LODs were11.7 μM and 3.6 mM, respectively. Furthermore, the Pd-Pt-Ir nanozyme was applied for the rapid detection of ascorbic acid, and a test strip w...
