研究目的
Exploring the use of the occlusion electrodeposition (OE) process for creation of an Inorganic /organic interface (IOI) between poly terthiophene (PTTh) and CdS, TiO2, and Zn-WO3 (Zn-doped WO3) to judge the effects on the photoelectron-chemical behavior of the created IOI assemblies.
研究成果
The occlusion electrodeposition method is reliable and effective for the creation of inorganic/organic interfaces. The photocurrent produced by each assembly is controlled by the band alignments between each assembly's components, with PTTh/CdS showing the greatest photocurrent. The presence of oxygen plays a crucial role in enhancing charge separation.
研究不足
The study does not address the long-term stability of the photoactive inorganic/organic interfaces under continuous illumination or in various environmental conditions.
1：Experimental Design and Method Selection:
The study utilized cyclic voltammetry (CV) technique for the electropolymerization of PTTh and the occlusion electrodeposition of inorganic nanoparticles (CdS, TiO2, and Zn-WO3) into PTTh films.
2：Sample Selection and Data Sources:
FTO electrodes were used as working electrodes in a three-electrode cell setup.
3：List of Experimental Equipment and Materials:
A BAS 100W electrochemical analyzer, Shimadzu UV-2101 PC for reflectance spectra, and a 300 watt xenon lamp solar simulator for irradiation.
4：Experimental Procedures and Operational Workflow:
The process involved repetitive cycling of the FTO electrode potential in acetonitrile suspensions containing the monomer and inorganic nanoparticles.
5：Data Analysis Methods:
Spectroscopic and electrochemical techniques were used to investigate the energy band gap structures of the assemblies.
