| 中文摘要 | au@pd core-shell nanoparticles (nps) were synthesized using seed-mediated method, and three samples with different shell structures were obtained by tuning the au core size. the shape-dependent catalytic activities of au@pd core-shell nps toward ethanol oxidation in alkaline electrolytes were systematically explored. the electrochemical experiments showed that the au@pd-2 core-shell nps (with au core size of 9.8 nm and loose pd shell) exhibited a distinctly higher activity and poison-resistance for the ethanol oxidation than other core-shell structures. based on the au@pd-2 core-shell nps and pd nps, two amperometric ethanol gas sensors were fabricated. during the sensor tests, the ethanol sensor based on au@pd-2 nps showed good performance for ethanol in the range of 50-600 ppm with sensitivity of 178.5 na ppm(-1) and less than 5% signal loss in 60 days. 2012 published by elsevier b.v. |
