“…Catalysts play a crucial role in HDC reactions. At present, the commonly used catalysts for HDC reactions include Pd, − Rh, Pt, − Ni, , and Co, among which the Pd-based catalysts are commonly recognized as the most promising one. In addition, the bimetallic Pd-M catalysts (M = Fe, Co, , Ni, Cu, , Au, − or Ag − ) can enhance the catalytic performance compared to their monometallic counterparts due to the synergistic effect between Pd and M. Moreover, using non-noble metals as the second metal can also decrease the cost of the catalysts.…”
