Combined Experimental and Theoretical Investigation of the Origin of Magnetic Anisotropy in Pentagonal Bipyramidal Isothiocyanato Co(II), Ni(II), and Fe(III) Complexes with Quaternary-Ammonium-Functionalized 2,6-Diacetylpyridine Bisacylhydrazone
(The Journal of Physical Chemistry C, 2019)
Magnetic anisotropy in pentagonal bipyramidal complexes of Co(II) (1 and 2), Fe(III) (3 and 4), and Ni(II) (5) with a 2,2′-[2,6-pyridinediylbis(ethylidyne-1-hydrazinyl-2-ylidene)]bis[N,N,N-trimethyl-2-oxoethanaminium] ...
Electrochemical Stability and Degradation Mechanisms of Commercial Carbon-Supported Gold Nanoparticles in Acidic Media
(The Journal of Physical Chemistry C, 2021)
Electrochemical stability of a commercial Au/C catalyst in an acidic electrolyte has been investigated by an accelerated stress test (AST), which consisted of 10,000 voltammetric scans (1 V/s) in the potential range between ...
Electrochemical Stability and Degradation of Commercial Pd/C Catalyst in Acidic Media
(The Journal of Physical Chemistry C, 2021)
Palladium has attracted significant attention as a catalyst or co-catalyst for many electrochemical reactions in energy conversion devices. We have studied electrochemical stability of a commercial Pd/C sample in an acidic ...
Reversible Olefin Addition to Extended Lattices of a Nickel–Selenium Framework
(The Journal of Physical Chemistry C, 2018)
We performed density functional theory computations to study the structural and electronic properties as the basis of ethylene addition activity for [Ni(XC)4]n (X = Se, S)-extended lattices. We demonstrated that the mechanism ...
Single-Atom Catalysts Supported by Graphene and Hexagonal Boron Nitride: Structural Stability in the Oxygen Environment
(The Journal of Physical Chemistry C, 2022)
Despite ample studies devoted to single-atom catalysts (SACs) based on two-dimensional materials, their structural robustness under atmospheric conditions has not been addressed so far. Using density functional theory, we ...
Aerosol Synthesis and Gas-Phase Photoelectron Spectroscopy of Ag-Bi-I Nanosystems
(The Journal of Physical Chemistry C, 2020)
We report on the aerosol generation of ligand-free silver iodobismuthate (Ag-Bi-I) nanoparticles (NPs) and on in situ investigation of their electronic structure using synchrotron radiation soft X-ray aerosol photoelectron ...
Velocity Map Imaging VUV Angle-Resolved Photoemission on Isolated Nanosystems: Case of Gold Nanoparticles
(The Journal of Physical Chemistry C, 2020)
We present an angle-resolved photoelectron spectroscopy study on isolated gold nanoparticles in the photon energy range between 6 and 12 eV performed at the DESIRS beamline of Synchrotron SOLEIL with a velocity map imaging ...
Electronic Properties of Silver–Bismuth Iodide Rudorffite Nanoplatelets
(The Journal of Physical Chemistry C, 2022)
Silver–bismuth iodide (Ag–Bi–I) rudorffites are chemically stable and non-toxic materials that can act as a possible lead-free replacement for methylammonium lead halides in optoelectronic applications. We report on a ...
