| 英文摘要 | Supported Au catalysts have been reported to exhibit high ethylene selectivity in the hydrogenation of acetylene, but the conversion is relatively low. Adding a second metal to Au has proven to be a promising approach to enhance its catalytic performance in acetylene hydrogenation. In this work, SiO2-supported Au-Ni bimetallic catalysts were synthesized and investigated in the selective hydrogenation of acetylene. The Au-Ni bimetallic catalysts exhibited much higher catalytic performance than that of the corresponding monometallic Au or Ni catalysts. By tuning the reduction temperature and/or Ni loading, we obtained an Au-Ni/SiO2 catalyst with optimal performance. The results of transmission electron microscopy imaging revealed that the Au-Ni bimetallic particles were highly dispersed on the SiO2 support. Meanwhile, analysis of the bimetallic catalyst by energy-dispersive X-ray spectroscopy, high-resolution transmission electron microscopy, and in situ diffuse reflectance infrared Fourier transform spectroscopy demonstrated the formation of Au-Ni alloy, which contributed to the synergistic effect between Au and Ni in the hydrogenation of acetylene.
