Nanoporous BiVO4/TiO2/Ti Film Photoelectrochemical Properties

Experimental data from the fabrication and characterization of nanoporous BiVO4/TiO2/Ti heterojunction films for photoelectrochemical water splitting. The dataset includes measurements from films prepared at five different electrodeposition times (10, 30, 100, 500, and 1000 seconds). It contains results from morphological, crystallographic, and photoelectrochemical analyses, including photocurrent density and charge transfer resistance.

Use Cases

• Analyze the relationship between electrodeposition time and photocurrent density, such as the 0.3363 mA/cm2 value recorded for the 1000-second film.
• Model the correlation between electrodeposition time and UV-vis absorption intensities to predict optical properties.
• Compare transient decay times between BiVO4/TiO2/Ti (3.2 s) and TiO2/Ti (0.95 s) films to quantify photocatalytic efficiency improvements.
• Use electrochemical impedance spectroscopy data to evaluate charge transfer resistance under irradiation for different film preparations.

Strengths

• Contains precise experimental measurements, including a photocurrent density of 0.3363 mA/cm2 and a transient decay time of 3.2 seconds.
• Systematically tests five distinct electrodeposition time conditions (10, 30, 100, 500, and 1000 s) for controlled variable analysis.
• Includes comparative data between BiVO4/TiO2/Ti and TiO2/Ti films for key performance metrics like band gap and decay time.

Limitations

• The dataset is derived from a single experimental study, limiting statistical power and generalizability.
• No information is provided on the number of data points, rows, or replicates for each measurement condition.
• Data is specific to a single fabrication method (electrodeposition followed by annealing at 450°C for 2 hours) and may not represent other synthesis techniques.
