Apr 2, 2020 · The Mo(IV) ions favor the adsorption and activation of N 2, while the FeS 2 substrate depresses the competitive hydrogen evolution reaction, and the two factors jointly endow the catalyst with a high Faraday efficiency of 14.41% at −0.2 V versus RHE.

Aug 1, 2024 · In this study, Mo doped FeS 2 nanosheet with rich sulfur vacancies (SVs) grown on activated carbon fibers was successfully synthesized and employed as a PMS activator to remove sulfamethazine (SMT), ARB and ARGs in aqueous solution.

Dec 30, 2024 · There is a strong interfacial coupling through electrons. The Mo-FeS 2 /Ni 3 S 2 @C exhibits excellent OER activity in alkaline solution. The development of high-performance oxygen evolution reaction (OER) electrocatalysts is quite pivotal to facilitate hydrogen production.

Apr 26, 2021 · It is believed that the MoS 2 /FeS nanocomposite represents an efficient heterogeneous Fenton catalyst that can greatly promote the performance of advanced oxidation processes (AOPs) for solving practical environmental issues.

Dec 15, 2022 · Sulfur vacancy-enriched FeS2@MoS2 is developed to activate peroxymonosulfate for efficient degradation of refractory organic pollutants in water.

Mar 1, 2025 · In this work, MoS 2 /FeS 2 nanocomposites were synthesized by a green and simple one-step hydrothermal method to improve the poor Fenton-like activity of MoS 2. A series of characterization techniques demonstrated that the MoS 2 and FeS 2 were chemically and firmly bonded through the Mo-S-Fe bonding.

Aug 5, 2024 · Low H2O2 utilization efficiency for hydroxyl radical generation, acidic pH, and recyclability are critical limitations of heterogeneous Fenton and photo-Fenton catalysts. The present research shows that the optimum Mo doping of FeS2 particles can largely alleviate these catalysis constraints.

In this study, Mo doped FeS 2 nanosheet with rich sulfur vacancies (SVs) grown on activated carbon fibers was successfully synthesized and employed as a PMS activator to remove sulfamethazine (SMT), ARB and ARGs in aqueous solution.

Inspired by the natural nitrogenase, we biomimetically designed an inorganic catalyst, Mo(IV)-doped FeS2, for electroreduction of dinitrogen to ammonia. The Mo(IV) ions favor the adsorption and activation of N2, while the FeS2 substrate depresses the competitive hydrogen evolution reaction, and the two factors jointly endow the catalyst with a ...

Although MoS 2 is a good candidate to replace noble metal Pt-based electrocatalysts for the hydrogen evolution reaction (HER), the comprehensive performances are still unsatisfactory. In this work, FeS 2 @MoS 2 heterostructures are proposed …
