Worldwide NH3 production reached 0.18 Gton in 2019, and 1–2% of the global CO2 emissions are due to large-scale NH3 synthesis (1 billion tons of CO2 / year). A catalyst for ammonia synthesis has been obtained by pyrolysis of iron phthalocyanine (Fe

Low-temperature hydrogen production from methanol over a ruthenium catalyst in water
Autor: Sanjay Kumar Singh, Rohit K. Rai, Silke Behrens, Mahendra Kumar Awasthi
Publikováno v: Catalysis Science & Technology. 11:136-142
Traditionally, methanol reforming at a very high temperature (>200 °C) has been explored for hydrogen production. Here, we show that in situ generated ruthenium nanoparticles (ca. 1.5 nm) from an organometallic precursor promote hydrogen production

Highly efficient and very stable iron and/or cobalt-based catalysts for the ammonia synthesis reaction were synthesized by one-step pyrolysis of metal phthalocyanine precursors. The presence of alkaline earth or alkali metals is found to be essential

Aqueous phase semihydrogenation of alkynes over Ni–Fe bimetallic catalysts
Autor: Sudipta Roy Barman, Rohit K. Rai, Sanjay Kumar Singh, Mahendra Kumar Awasthi, Silke Behrens, Vipin Kumar Singh
Publikováno v: Catalysis Science & Technology. 10:4968-4980
Bimetallic Ni–Fe catalysts (Ni/Fe, 1 : 1, 1 : 3, and 3 : 1) are synthesized and explored for their catalytic activity in semihydrogenation of internal alkynes using H2 gas in water–ethanol solution. Our findings revealed that over the Ni1Fe3 cata

Ruthenium Complexes for Catalytic Dehydrogenation of Hydrazine and Transfer Hydrogenation Reactions
Autor: Deepika Tyagi, Soumyadip Patra, Sanjay Kumar Singh, Shaikh M. Mobin, Mahendra Kumar Awasthi, Rohit K. Rai
Publikováno v: Chemistry - An Asian Journal. 13:1424-1431
Catalytic dehydrogenation of hydrazine was achieved over iminopyridine ligated ruthenium-arene complexes, where the release of H2 gas, as confirmed by GC-TCD, from hydrazine depends on reaction temperature, base, and solvents. NMR and MS studies indi

N-Substituted Iminopyridine Arene-Ruthenium Complexes for the Regioselective Catalytic Hydration of Terminal Alkynes
Autor: Shaikh M. Mobin, Rohit K. Rai, Deepika Tyagi, Sanjay Kumar Singh
Publikováno v: Asian Journal of Organic Chemistry. 6:1647-1658
A series of N-substituted iminopyridine ligands (L1-OH - L3-iPr) based arene-Ru(II) complexes with general formula [(η6-arene)Ru(N,N'-R")Cl]+ was synthesized and characterized by NMR, mass spectrometry, and single crystal X-ray diffraction studies.
