TL;DR: It is demonstrated that illuminated hydrogen-terminated diamond yields facile electron emission into water, thus inducing reduction of N₂ to NH₃ at ambient temperature and pressure.
Abstract: The photocatalytic reduction of N₂ to NH₃ is typically hampered by poor binding of N₂ to catalytic materials and by the very high energy of the intermediates involved in this reaction. Solvated electrons directly introduced into the reactant solution can provide an alternative pathway to overcome such limitations. Here we demonstrate that illuminated hydrogen-terminated diamond yields facile electron emission into water, thus inducing reduction of N₂ to NH₃ at ambient temperature and pressure. Transient absorption measurements at 632 nm reveal the presence of solvated electrons adjacent to the diamond after photoexcitation. Experiments using inexpensive synthetic diamond samples and diamond powder show that photocatalytic activity is strongly dependent on the surface termination and correlates with the production of solvated electrons. The use of diamond to eject electrons into a reactant liquid represents a new paradigm for photocatalytic reduction, bringing electrons directly to reactants without requiring molecular adsorption to the surface.
TL;DR: In this paper, a homologous series of eight compounds of the general structure A-Sp-B where B is 4-biphenylyl, Sp is a rigid saturated hydrocarbon spacer, the steroidal 5-cap alpha-androstane skeleton, and A is one of a series of 8 different molecular groups with π.. electron networks was synthesized.
Abstract: A homologous series of eight compounds of the general structure A-Sp-B where B is 4-biphenylyl, Sp is a rigid saturated hydrocarbon spacer, the steroidal 5..cap alpha..-androstane skeleton, and A is one of a series of 8 different molecular groups with ..pi.. electron networks was synthesized. A liquid solution of these molecules in either 2-methyltetrahydrofuran or isooctane at room temperature was subjected to a 30-ps pulse of solvated electrons. Data are presented that demonstrate in these systems the dependence of the electron transfer rates on the exothermicity of the reaction and on solvent polarity. It is also noted that the electron transfer reactions are free ion reactions.
TL;DR: In this article, a discretized version of Feynman's path integral is used for the numerical investigation of the properties of an electron solvated in molten KC1. But the local structure around the solute electron appears to be different from that of an F center in the solid.
Abstract: It is shown that a discretized version of Feynman’s path integral provides a convenient tool for the numerical investigation of the properties of an electron solvated in molten KC1. The binding energy and the pair correlation functions are calculated. The local structure around the solute electron appears to be different from that of an F center in the solid.
