Growth of well-ordered iron sulfide thin films

Abstract

Preparation and structural analysis of well-ordered, single-crystalline, hexagonal iron sulfide thin films for use in model catalysis studies.

Accelerated optimization of pure metal and ligand compositions for light-driven hydrogen production

“…To complete the identification, the XPS spectra from each metal was compared to literature XPS spectra for different metal containing compositions. 42–45…”

Effects of Alternating Magnetic Fields on the OER of Heterogeneous Core–Shell Structured NiFe2O4@(Ni, Fe)S/P

“…The B.E. of 706.9 eV (707.5 eV) corresponded to Fe–S for S-NFO-Ms/C (Fe–P for P-NFO-Ms/C) . In the resolved high-resolution spectra of Ni 2p 3/2 (Figure c), the B.E.s of 855.1, 858, 854, and 853.6 eV corresponded to the Ni 2+ in NiFe 2 O 4 , Ni 3+ , Ni–S, and Ni–P. ,, …”

“…Modulating the surface electron density of catalysts was an effective method to optimize the Gibbs free energy of adsorption. , The sulfur/phosphate treatment induced the charge redistribution in the material. Several researches have proven that it would optimize the adsorption of intermediates and reduce the Gibbs free energy, which contributed to the improvement in OER activity …”

“…of 706.9 eV (707.5 eV) corresponded to Fe−S for S-NFO-Ms/C (Fe−P for P-NFO-Ms/C). 34 In the resolved high-resolution spectra of Ni 2p 3/2 (Figure 4c), the B.E.s of 855. The relative proportions of the different valence states are measured by the area of the resolved peaks in the high-resolution spectra.…”

“…Several researches have proven that it would optimize the adsorption of intermediates and reduce the Gibbs free energy, which contributed to the improvement in OER activity. 34 Electrochemical impedance spectroscopy (EIS) could be applied to study the charge transport ability. 40 The highfrequency phase of EIS (Figure 5e and equivalent circuit diagram for EIS as inset) was associated with the internal resistance of the system (R S ).…”
