研究目的
Investigating the fabrication of black titania (b-TiOx) via atomic layer deposition (ALD) for enhanced energy storage and photoelectrochemical applications.
研究成果
ALD b-TiOx shows significant improvements in capacitance and photocurrent over conventional TiO2, with potential applications in energy storage and photoelectrochemical devices.
研究不足
The study focuses on the fabrication and initial characterization of b-TiOx via ALD. Further optimization and application in devices are needed.
1:Experimental Design and Method Selection:
ALD was used for the direct deposition of b-TiOx without deoxygenation annealing.
2:Sample Selection and Data Sources:
ZnO nanowire arrays were used as substrates for b-TiOx deposition.
3:List of Experimental Equipment and Materials:
Cambridge Fiji tool for ALD, Tetrakis(dimethylamido)titanium (TDMAT), H2O, argon carrier gas.
4:Experimental Procedures and Operational Workflow:
Sequential pulsing of TDMAT and H2O in an ALD chamber to deposit b-TiOx.
5:Data Analysis Methods:
SEM/EDS for characterization, cyclic voltammetry for electrochemical testing, photoelectrochemical measurements under lit and dark conditions.
