TL;DR: Providing a future energy supply that is secure and CO_2-neutral will require switching to nonfossil energy sources such as wind, solar, nuclear, and geothermal energy and developing methods for transforming the energy produced by these new sources into forms that can be stored, transported, and used upon demand.
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
A cobalt-based catalyst for the hydrogenation of CO2 under ambient conditions.
TL;DR: A cobalt-based catalyst system for the production of formate from CO2 and H2 is designed and the results highlight the value of fundamental thermodynamic properties in the rational design of catalysts.
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.
Journal ArticleDOI
Determining the Overpotential for a Molecular Electrocatalyst
Aaron M. Appel,Monte L. Helm +1 more
TL;DR: In this paper, the authors provide a clear and concise description of overpotential and recommendation for its determination in molecular electrocatalysis, based upon work supported as part of the Center for Molecular Electrocatalysis.
