研究目的
To develop a one-step, simple, efficient, and low-cost strategy for preparing highly stable hybrid platinum-titania (Pt@TiO2) photocatalysts and evaluate their photocatalytic activity and self-cleaning properties under solar light.
研究成果
The hybrid Pt@TiO2 nanocomposites exhibit high photocatalytic activity and self-cleaning properties under solar light, making them promising for environmental and textile applications.
研究不足
The study focuses on the photocatalytic activity and self-cleaning properties of Pt@TiO2 nanocomposites under solar light, but the long-term stability and scalability of the synthesis method may require further investigation.
1：Experimental Design and Method Selection:
A solvothermal wet chemical process was used to synthesize hybrid Pt@TiO2 nanocomposites.
2：Sample Selection and Data Sources:
Titanium(IV) butoxide and hydrogen hexachloroplatinate(IV) were used as precursors with DMSO as a solvent and surfactant.
3：List of Experimental Equipment and Materials:
XRD, TEM, UV–vis spectroscopy, EDXRF, TGA, and FTIR were used for characterization.
4：Experimental Procedures and Operational Workflow:
The solution was heated to 190°C for 1 h, centrifuged, rinsed, dried, and calcined at 400°C.
5：Data Analysis Methods:
XRD patterns were analyzed using the Rietveld method, and photocatalytic activity was evaluated by the degradation of diuron under solar light.
