Heterogeneous Catalysis

Heterogeneous Catalysis

Heterogeneous catalysis involves a catalyst in a different phase from the reactants. It is a process where the catalyst and the reactants are in distinct phases, typically solid and gas or liquid.Most heterogeneous catalysts are metals, metal oxides, or acids. The list includes transition metals like iron (Fe), cobalt (Co), nickel (Ni), palladium (Pd), platinum (Pt), chromium (Cr), manganese (Mn), tungsten (W), silver (Ag), and copper (Cu). These metals possess partially vacant d orbitals that...

Background:

Surface functionalization of 2D semiconductors precisely tunes electronic and optical properties.
Exploring oxidation-dependent nonlinear optical properties is limited by the lack of in situ characterization techniques.

Purpose of the Study:

To develop an in situ technique for controlling and monitoring oxidation-mediated nonlinear optical properties of 2D semiconductors.
To investigate the transition of nonlinear absorption in ReS2 during electrochemical oxidation.

Main Methods:

Developed an electrochemical method for selective surface oxidation of ReS2.
Integrated electrochemical oxidation with a Z-scan setup to create an in situ electrochemical Z-scan system.
Utilized theoretical calculations (band alignment, density of states) to support experimental findings.

Main Results:

Successfully controlled the surface oxidation of ReS2 electrochemically.
Observed a transition in nonlinear absorption from two-photon absorption to saturable absorption with increasing oxidation.
Demonstrated that ReS2's two-photon absorption decreases while ReO3's saturable absorption enhances.

Conclusions:

The developed in situ electrochemical Z-scan technique is effective for controlling surface oxidation and monitoring nonlinear optical properties.
This technique offers a simple, nondestructive approach for studying oxidation effects in 2D materials.
The findings provide insights into tuning optoelectronic properties of 2D semiconductors through controlled oxidation.
