研究目的
Investigating the selective growth of Pd nanocrystals on the (100) facets of truncated octahedral Cu2O for UV plasmon-enhanced photocatalysis.
研究成果
The selective crystalline growth of Pd nanocrystals on the (100) facets of truncated octahedral Cu2O was successfully conducted, leading to significant enhancements in photocatalytic activities under UV light due to the hot electron effect.
研究不足
The study focuses on the selective growth of Pd NCs on Cu2O and its photocatalytic enhancement under UV light, but does not explore the full solar spectrum or other potential applications.
1：Experimental Design and Method Selection:
The selective deposition of Pd NCs on the (100) facets of truncated octahedral Cu2O was prepared using a Pd precursor ethanol solution under visible light irradiation.
2：Sample Selection and Data Sources:
Truncated octahedral Cu2O microcrystals were used.
3：List of Experimental Equipment and Materials:
SEM, TEM/HRTEM, XRD, and UV-vis absorption spectra were used for characterization.
4：Experimental Procedures and Operational Workflow:
The selective growth of Pd NCs was determined by SEM, TEM/HRTEM, XRD and UV-vis absorption spectra. The UV plasmon-enhanced photocatalytic activities were proved by testing under single wavelength UV light irradiation.
5：Data Analysis Methods:
The photocatalytic activities were analyzed based on the enhancement factors at specific wavelengths.
