Abstract:
It is highly desirable to develop efficient and durable oxygen evolution reaction (OER) electrocatalysts. Herein, we report the in situ development of an Fe-(tetracyanoquinodimethane)2 nanowire array on Fe foil (Fe(TCNQ)2/Fe) via a solution immersion method. As a non-noble-metal OER electrocatalyst, such Fe(TCNQ)2/Fe needs an overpotential of only 340 mV to drive a geometrical catalytic current density of 10 mA cm-2 in 1.0 M KOH. Notably, it also shows strong long-term electrochemical durability capable of maintaining its catalytic activity for at least 110 h.

Noble Gases
The elements in group 18 are noble gases (helium, neon, argon, krypton, xenon, and radon). They earned the name “noble” because they were assumed to be nonreactive since they have filled valence shells. In 1962, Dr. Neil Bartlett at the University of British Columbia proved this assumption to be false.

SN2 Reaction: Kinetics
In a chemical reaction, a relationship exists between the concentration of reactants and the rate at which the reaction proceeds. The study to measure this relationship is known as the kinetics of a chemical reaction. Kinetic studies are used to deduce the rate law of a chemical reaction, which provides information about the species involved during the transition state of the rate-determining step. Thus, kinetic studies help to derive the mechanism of a...

SN2 Reaction: Mechanism
The presence of the more electronegative halogen in the substrate creates a polarized carbon-halide bond. The halide pulls the electron cloud generating an electrophilic center at the carbon atom. Thus, the carbon atom carries a partial positive charge while the halide has a...
SN2 Reaction: Transition State
When the nucleophile approaches the electrophilic carbon with its lone pairs, the halide acts as a leaving group and moves away with the electron-pair bonded to the carbon. Dotted partial bonds represent the bonds being formed or broken...
