Preparation and Reactions of Sulfides

Preparation and Reactions of Sulfides

Sulfides are the sulfur analog of ethers, just as thiols are the sulfur analog of alcohol. Like ethers, sulfides also consist of two hydrocarbon groups bonded to the central sulfur atom. Depending upon the type of groups present, sulfides can be symmetrical or asymmetrical. Symmetrical sulfides can be prepared via an SN2 reaction between 2 equivalents of an alkyl halide and one equivalent of sodium sulfide.

Background:

Transition metal sulfides (TMSs) show potential as noble-metal-free electrocatalysts for water splitting.
Controlling the *in situ* structural reconfiguration of TMSs during the oxygen evolution reaction (OER) to form active sites remains a challenge.

Purpose of the Study:

To precisely control the *in situ* reconfiguration of transition metal sulfides for enhanced OER activity.
To design and synthesize (Ni,Fe)S2/MoS2 heterostructures for efficient electrochemical water splitting.

Main Methods:

Heterojunction engineering of (Ni,Fe)S2/MoS2 catalysts.
Electrochemical characterization to evaluate OER activity and stability.
Analysis of *in situ* structural reconfiguration during electro-oxidation.

Main Results:

The (Ni,Fe)S2/MoS2 heterostructure undergoes controlled reconfiguration, forming Ni(OH)2/NiOOH/FeOOH active sites.
Achieved excellent OER activity with a low overpotential of 228 mV at 100 mA cm⁻².
Demonstrated a low voltage of 1.44 V at 10 mA cm⁻² in an alkaline water electrolyzer, outperforming Mo-free catalysts.

Conclusions:

Precise control over electrochemical reconstruction is crucial for designing high-performance electrocatalysts.
Heterojunction engineering offers a pathway to create tailored active sites for efficient water splitting.
The developed (Ni,Fe)S2/MoS2 catalyst represents a low-cost and efficient alternative for electrochemical water splitting.
