Journal ArticleDOI
Beyond fossil fuel-driven nitrogen transformations.
Jingguang G. Chen,Jingguang G. Chen,Richard M. Crooks,Lance C. Seefeldt,Kara L. Bren,R. Morris Bullock,Marcetta Y. Darensbourg,Patrick L. Holland,Brian M. Hoffman,Michael J. Janik,Anne K. Jones,Mercouri G. Kanatzidis,Paul W. King,Kyle M. Lancaster,Sergei V. Lymar,Peter H. Pfromm,William F. Schneider,Richard R. Schrock +17 more
TL;DR: Research prospects for more sustainable routes to nitrogen commodity chemicals are reviewed, considering developments in enzymatic, homogeneous, and heterogeneous catalysis, as well as electrochemical, photochemical, and plasma-based approaches.
Journal ArticleDOI
A Synthetic Nickel Electrocatalyst with a Turnover Frequency Above 100,000 s−1 for H2 Production
Monte L. Helm,Monte L. Helm,Michael P. Stewart,R. Morris Bullock,M. Rakowski DuBois,Daniel L. DuBois +5 more
TL;DR: A synthetic nickel complex catalyzes the production of H2 using protonated dimethylformamide as the proton source, with turnover frequencies of 33,000 per second in dry acetonitrile and 106,000 s−1 in the presence of 1.2 M of water.
BookDOI
Catalysis without precious metals
TL;DR: In this paper, the authors discuss the role of catalysts in catalytic reduction of molecular Nitrogen Interconversion of Mo(NH3) and Mo(N2) using the second coordination sphere to control the movement of Protons between the metal and the exterior of the molecular catalysts.
Journal ArticleDOI
[Ni(PPh2NC6H4X2)2]2+ Complexes as Electrocatalysts for H2 Production: Effect of Substituents, Acids, and Water on Catalytic Rates
Uriah J. Kilgore,John Roberts,Douglas H. Pool,Aaron M. Appel,Michael P. Stewart,M. Rakowski DuBois,William G. Dougherty,W. Scott Kassel,R. Morris Bullock,Daniel L. DuBois +9 more
TL;DR: Catalytic studies using acids with a range of pK(a) values reveal that turnover frequencies do not correlate with substrate acid pK(-1) values but are highly dependent on the acid structure, with this effect being related to substrate size.
Journal ArticleDOI
Thermodynamic Hydricity of Transition Metal Hydrides
Eric S. Wiedner,Matthew B. Chambers,Catherine L. Pitman,R. Morris Bullock,Alexander J. M. Miller,Aaron M. Appel +5 more
TL;DR: Methods for using hydricity values to predict chemical reactivity are discussed, including organic transformations, the reduction of CO2, and the production and oxidation of hydrogen.
