“…129 Similarly, In or Sn was also used to modify Ni species for the conversion of acetic acid to ethanol, affording relatively high ethanol yields (for instance: 93% over the 4wt%Ni-4wt%Sn/TiO 2 catalyst at 473 K, 10 MPa H 2 and 12 h). 130,131 For the hydrogenation of methyl acetate to ethanol, most researchers focus on Cu based catalysts due to the abundant reservation of Cu and the high activity for CvO bond hydrogenation. Over typical Cu based catalysts, Cu 0 sites split the gaseous H 2 into H*, and Cu + species activate the acyl species of methyl acetate.…”

The successful synthesis of finely tuned Ni1.5Sn nanoalloy phases containing ZnO catalyst with a small particle size (6.7 nm) from a mixed‐metal zeolitic imidazolate framework (MM‐ZIF) is investigated. The catalyst was evaluated for the efficient production of 1,2‐propanediol (1,2‐PDO) from crude glycerol and comprehensively characterized using several analytical techniques. Among the catalysts, 3Ni1Sn/ZnO (Ni/Sn=3/1) showed the best catalytic performance and produced the highest yield (94.2 %) of 1,2‐PDO at ~100 % conversion of glycerol; it also showed low apparent activation energy (15.4 kJ/mol) and excellent stability. The results demonstrated that the synergy between Ni−Sn alloy, finely dispersed Ni metallic sites, and the Lewis acidity of SnOx species‐loaded ZnO played a pivotal role in the high activity and selectivity of the catalyst. The confirmation of acetol intermediate and theoretical calculations verify the Ni1.5Sn phases provide the least energetic pathway for the formation of 1,2‐PDO selectively. The reusability of solvent for successive ZIF synthesis, along with the excellent recyclability of the ZIF‐derived catalyst, enables an overall sustainable process. We believe that the present synthetic protocol that uses MM‐ZIF for the conversion of various biomass‐derived platform chemicals into valuable products can be applied to various nanoalloy preparations.
