摘要：
Gold nanoparticles (AuNPs) modified cerium oxide (CeO2 or ceria) nanoparticles (AuNP-CeO2) were prepared with the direct deposition of AuNPs onto CeO2 surface. It was found the prepared nanoparticles have excellent electrocatalytic activity towards hydrazine oxidation. The catalytic activity of AuNP-CeO2 is much higher than CeO2, indicating possible synergistic effect between AuNPs and CeO2. The AuNP-CeO2 modified screen-printed electrode can be used as disposable electrochemical devices for hydrazine detection and the AuNP-CeO2 nanoparticles can also be used as electrode material for hydrazine fuel cell.
