“…In general, the high cost of noble metals, and sometimes their insufficient selectivity in the target dehydrogenation reaction, prompts reduction of the use of precious metal catalysts by the introduction of a second metal (Ni, Sn, Mn, etc. [9,[17][18][19][20][21]) and the search for alternative catalytic systems. In particular, non-precious monometallic catalysts based on Ni, Mo, Cu, Ag, Zn, and Sn have been proposed [22][23][24][25].…”
