研究目的
Investigating the photoconversion efficiency for photoelectrochemical water splitting using nanocaves TiO2 and highly uniformed TiO2 nanotubes.
研究成果
The highest photocurrent density i.e. 5.77 mA cm-2 at 1.23 V vs. RHE was obtained from nanocaves TiO2 photoanode. The incorporation of Cu resulted in a reduction in photocatalytic activity of the oxygen evaluation reaction (OER) and an increase of the hydrogen evolution reaction (HER).
研究不足
The incorporation of Cu resulted in a reduction in photocatalytic activity of the oxygen evaluation reaction (OER).
1：Experimental Design and Method Selection:
The photoanodes were synthesized via electrochemical anodization of a titanium foil in a glycerol-based solution containing NH4F at 10 V. Pulse electrodeposition was used to incorporate Cu ions into the uniform TiO2 nanotubes.
2：Sample Selection and Data Sources:
The photoconversion efficiency performance was examined under simulated visible light illumination (? ≥ 380 nm) in a 1 M solution of NaOH.
3：List of Experimental Equipment and Materials:
Titanium foil, glycerol-based solution containing NH4F, NaOH solution.
4：Experimental Procedures and Operational Workflow:
Electrochemical anodization, pulse electrodeposition, photocurrent density measurement, Mott-Schottky analysis, EIS measurement.
5：Data Analysis Methods:
Analysis of photocurrent density, Mott-Schottky plots, EIS data, and photoconversion efficiency measurements.
