| 中文摘要: |
| 通过热裂解和氢还原制备了Ni纳米颗粒，并在酸性溶液中通过液相置换合成了核壳 Ni@Pt-800。采用喷涂法将催化剂作为阴极涂层附着在质子交换膜上，阳极涂层为商业Pt/C。采用透射电子显微镜、X射线光电子能谱仪、X射线衍射仪对催化剂结构进行表征。结果表明，Ni@Pt-800对甲醛的响应分别是Ni@Pt和其他干扰气体的4.95倍和25倍。在0～135×10?6范围内，甲醛的氧化峰电流与浓度有着良好的线性关系，其线性回归方程为：△i=0.00103×10?6－0.006 61，相关系数为0.98。 |

| Ni nanoparticles were prepared by thermal cracking and hydrogen reduction, and coreshell Ni@Pt-800 was synthesized by liquid-phase substitution in acidic solution. The catalysts were attached as cathodic coatings onto a proton exchange membrane using the spray method, and the anodic coatings were commercial Pt/C. The catalysts were characterized by transmission electron microscope, X-ray photoelectron spectrometer, and X-ray diffractometer. The results suggest that the response of Ni@Pt-800 to formaldehyde is 4.95 times of Ni@Pt and 25 times of the other interfering gases. In the range of 0-135×10?6, there is a good linear relationship between the oxidation peak current and concentration of formaldehyde, and the linear regression equation is: △i=0.00103×10?6－0.006 61, with a correlation coefficient of 0.98. |
