研究目的
To synthesize Cu2O particles with different morphologies using a simple chemical reduction method at room temperature by varying the molar concentration of CuCl2 precursor salt.
研究成果
A simple and effective method for the synthesis of Cu2O nanostructures with different shapes was developed by varying the concentration of copper chloride precursor salt. The shape of the particles was successfully changed from cubic to octahedral, truncated octahedral, and cubic truncated by adjusting the precursor salt concentration. The synthesized particles were characterized and confirmed to have the desired morphologies and sizes.
研究不足
The absence of a surfactant agent affects the dispersivity of the samples. The structural stability of the Cu2O particles without the addition of surfactants changes over time, except for the octahedral shape particles.
1：Experimental Design and Method Selection:
A simple chemical reduction method at room temperature was used to synthesize Cu2O particles with different morphologies by varying the molar concentration of CuCl2 precursor salt.
2：Sample Selection and Data Sources:
Cu2O particles were synthesized directly in aqueous solution by varying the molar concentration of CuCl2 precursor salt added to the sodium borohydride NaBH4 as a reducing agent.
3：List of Experimental Equipment and Materials:
Copper chloride dihydrate (CuCl2.2H2O) and sodium borohydride (NaBH4) were used as chemical reagents.
4：2H2O) and sodium borohydride (NaBH4) were used as chemical reagents.
Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: The reaction was carried out by mixing 10 ml of precursor salt and 12 ml of reducing agent at a speed of 0.348 cm/s under magnetic stirring and room temperature. After three hours, the solids were recovered by centrifugation, washed, and dried.
5：348 cm/s under magnetic stirring and room temperature. After three hours, the solids were recovered by centrifugation, washed, and dried.
Data Analysis Methods:
5. Data Analysis Methods: The morphology and chemical composition of the Cu2O particles were determined using TEM, SEM, XRD, and UV-vis techniques.
