Hydrothermal synthesis of FeS2 as a highly efficient …
2020年10月1日 · In this study, we demonstrated that hydrothermal synthesized FeS 2 was highly efficient to catalyze the H 2 O 2 decomposition for diclofenac sodium (DCF) degradation in a wide range of initial pH (3–9) by heterogeneous electro-Fenton (EF) process, and this “Pyrite-EF” showed a better performance for the mineralization of DCF in comparison with t...
Surface XPS core-level shifts of FeS2 - ScienceDirect
2003年5月15日 · The XPS S 2p core-level spectra of pyrite FeS 2 have been measured to study the surface core-level shifts (SCLSs). In addition to the previously found features on the low binding energy (BE) side of the line, evidence for a new structure on the high BE side is given.
Nitrogen doped FeS2 nanoparticles for efficient and stable …
2021年5月1日 · The band structure and electronic state of FeS 2 are modulated by a nitrogen doping strategy, as confirmed by X-ray photoelectron spectroscopy (XPS), X-ray absorption spectroscopy (XAS) and density functional theory (DFT) calculations.
XPS of (a) Fe 2p and (b) S 2p of FeS 2 thin films sulfurized at ...
A simple one-step hydrothermal method was developed to synthesize pyrite (FeS2) sheet- and bulklike pyrite mineral. The Fe/S molar ratio determines the phase of FeS2, including pyrite and...
Optimizing Reversible Phase‐Transformation of FeS2 Anode via …
2024年11月18日 · In this work, we present a proof-of-concept demonstration of designing and constructing a honeycomb-like hybrid of FeS 2 nanoparticles coupled with N-doped carbon (NC) nanosheet supported SAs Mn (FeS 2 /SAs Mn@NC) toward fast-charging sodium storage.
Sulfur Spectra – FeS2 – Pyrite – natural crystal - XPS Database
The XPS Spectra section provides raw and processed survey spectra, chemical state spectra, BE values, FWHM values, and overlays of key spectra. Atom% values from surveys are based on sample, as received, and Scofield cross-sections. Atom% values are corrected for IMFP and PE. Peak-fits are guides for practical, real-world applications.
High resolution XPS spectra of Fe 2p (a) and O 1s (b) in
Low-cost, robust counter electrode (CE) with merits of superior catalytic activity and long-term stability, rapid electron/mass transporting is highly desirable for dye-sensitized solar cell (DSC).
FeS2 的表面 XPS 核心级转变,Applied Surface Science - X-MOL
已测量黄铁矿 FeS2 的 XPS S 2p 核能级光谱以研究表面核能级位移 (SCLS)。 除了先前发现的线的低结合能 (BE) 侧的特征外，还提供了高 BE 侧新结构的证据。 这个特征似乎是表面敏感的。 还发现最终状态效应可能对 SCLS 做出显着贡献。 已测量黄铁矿 FeS2 的 XPS S 2p 核能级光谱以研究表面核能级位移 (SCLS)。 除了先前发现的线的低结合能 (BE) 侧的特征外，还提供了高 BE 侧新结构的证据。 这个特征似乎是表面敏感的。 还发现最终状态效应可能对 SCLS 做出显着贡献。
