Magnesium iodide (MgI) solid-electrolyte interface (SEI) layers have previously been shown to protect Mg metal anodes from passivation through products formed during Mg(TFSI) electrolyte decomposition (TSFI = trifluorosulfonimide). MgI formed from small quantities of I added to the electrolyte shows a drastic decrease in the overpotential for magnesium deposition and stripping. In this work, a MgI SEI layer was created in an fashion and then the electrochemical characteristics of this MgI SEI layer were probed both alone and with small quantities of I or BuNI additives to identify the electroactive species.

Under varied annealing temperatures, the degree of Mg and Fe site inversion changes the optical, electronic, and composition of the nanoparticles. A small particle size of ∼10 nm is achievable with the aid of an ammonium salt mineralizer that caps the particles during nucleation and growth.

Forming in a platelet morphology, these particles are as small as 20 nm with a BET surface area of 37 m g WO. These nanoplatelets are active for the photocatalytic oxidation of the 1° alcohols benzyl alcohol (rate constant, of 2.
