Background:
- Nickel telluride (NiTe2) is a promising material with potential applications.
- Controlling the synthesis of nanostructured materials is crucial for optimizing their properties.
- Hydrothermal synthesis offers a versatile route for nanomaterial fabrication.
Purpose of the Study:
- To develop a scalable method for synthesizing single-crystalline NiTe2 nanoplates.
- To investigate the role of Ethylenediaminetetraacetic acid (EDTA) in controlling NiTe2 nanostructure formation.
- To characterize the morphology and dimensions of the synthesized NiTe2 nanoplates.
Main Methods:
- Hydrothermal reaction using nickel acetate (Ni(CH3COO)2) and tellurium dioxide (TeO2).
- Utilizing Ethylenediaminetetraacetic acid (EDTA) as a chelating agent.
- Reaction conditions: 210 degrees C for 48 hours.
Main Results:
- Successful large-scale synthesis of single-crystalline NiTe2 nanoplates.
