研究目的
Investigating the controlled hydrothermal synthesis of K2Ti6O13 nanowires and their photo-electronic response for potential applications in solar cell and water splitting.
研究成果
The hydrothermal method developed allows for the controlled synthesis of K2Ti6O13 nanowires with uniform diameter and variable length, exhibiting strong UV absorption and stable photocurrent, indicating potential for applications in solar cells and water splitting.
研究不足
The study did not explore the impact of other reactants or conditions beyond KOH concentration and hydrothermal temperature and time. The potential applications in solar cells and water splitting were suggested but not extensively tested.
1：Experimental Design and Method Selection:
A hydrothermal method was developed using tetrabutyl titanate and KOH as reactants for the synthesis of K2Ti6O13 nanowires.
2：Sample Selection and Data Sources:
The reactants were tetrabutyl titanate and KOH, with deionized water used for dilution.
3：List of Experimental Equipment and Materials:
Autoclave, X-ray diffraction (XRD, D8 Advance, BRUKER corporation), scanning electron microscopy (SEM, ZEISS SUPRA?55, Carl Zeiss corporation), transmission electron microscopy (TEM, Tecnai G2 F30, FEI corporation), energy dispersive spectrum (EDS), UV-visible absorption spectrum (UV-2600, SHIMATSU corporation), electrochemical work station (CHI760E).
4：Experimental Procedures and Operational Workflow:
The mixture was heated in an autoclave at 200℃ for varying periods, washed, and characterized.
5：Data Analysis Methods:
XRD, SEM, TEM, EDS, UV-vis absorption, and photocurrent measurements were used for analysis.
