Molybdenum-catalysed ammonia production with samarium diiodide and alcohols or water

Catalytic Reactivity of Molybdenum–Trihalide Complexes Bearing PCP‐Type Pincer Ligands

“…However, unfortunately, the amount of ammonia did not exceed 415 equiv based on the Mo atom of the catalyst when 2 b was used as a catalyst. We believe that the achievement described in this paper provides valuable information to develop the ultimate reaction system for ammonia production under mild reaction conditions …”

Theoretical Screening of Single Transition Metal Atoms Embedded in MXene Defects as Superior Electrocatalyst of Nitrogen Reduction Reaction

“…[33] Inspired by these experimental progresses, [32,33] we explored the potential application of single atom embedded MXene nanosheets in electrocatalytic NRR. Because Mo plays an essential role in biological nitrogen fixation system, [34,35] and a series of Mo-containing materials have been studied as the promising NRR catalysts, [10,12,36,37] here we chose Mo 2 TiC 2 O 2 as the substrate to construct SACs. By using first-principles calculations, we systematically investigated the defective Mo 2 TiC 2 O 2 nanosheets embedded with 3d-, 4d-, and 5d-TM atoms (except Tc, Hg, and Lanthanide), labeled as Mo 2 TiC 2 O 2 -TM SA .…”

Ammonia Synthesis through Hydrolysis of a Trianionic Pincer Ligand‐Supported Molybdenum–Nitride Complex

“…[4] CO 2 production comes from two main sources: 1) CO 2 released from the consumption of energyr equired to drive the N 2 + +3H 2 $2NH 3 equilibrium at high temperature and pressure, and 2) CO 2 released during steam reforming of natural gas to synthesize H 2 .P rojected population growth [5] will only heighten the demand for ammonia production. Dinitrogen fixation [6] through homogeneous catalysis in the liquid phase at ambient temperatures and pressures is al ong-standing challenge, and recent catalystd iscoveries are encouraging, [7] butf ail to approacht he necessary efficiency for commercial production. [8][9][10][11][12][13][14][15][16][17][18][19] Electrochemical ammonia synthesis [19] at ambient pressure is another alternative that continues to receive significant attention, especially considering the potential for ammonia as ac arbon-free fuel.…”

“…[34] Nishibayashi recently reported 4350 equiv of ammonia production versus Mo using SmI 2 as the reductant and water as the protonsource. [7] Despite the prevalence of surface-nitride hydrolysis, homogeneous metal nitride hydrolysis to yield ammonia under neutral or non-aqueous conditions is less common. Perhapst he most relevante xample to the current work is the hydrolysis of (Ph 3 SiO) 3 MoN in the presence of 2,2'-bipyridine to yield the bis-oxo complex (Ph 3 SiO) 3 MoO 2 by Fürstner and co-workers; althoughl ikely the product, ammonia was not confirmed.…”
