Data for paper entitled "The role of Cu and film thickness on the photocatalytic activity of mesoporous spin coated TiO2 films"

Download (9.09 MB)

Most of the data is contained in an OriginPro 2023b file with each figure in a separate folder; folders are described below.

Parts of Figures 1 and 3 are data from photoelectron spectroscopy and are contained in VMS files with the ISO standard VAMAS format. They were created with the program CASAXPS version 2.3.24.

OriginPro file:

Figure 1a). Table of Y-columns: % stearic acid removed from the surface: X-Column Time/minutes.

Figure 2. Table of Y-columns: % stearic acid remaining at the surface: X-Column Time/seconds. Each Y column represents data from catalyst with different Cu wt%

Figure 3. b) Table of EXAFS data for 8 catalysts with different Cuwt% loading: X-column: X-ray energy/eV; Y column : absorption

Figure 3. c) Plot of derived proportion of CuO and Cu2O % in catalyst samples. X column: Catalyst labels; Y-column %CuO present.

Figure 4: Plots Film thicknesses against deposition spin speed. Y column Film thickness/10-6 m; X-column deposition spin speed in rpm.

Figure 5a Chart of calculated reaction Half lives (from data in Figure 1) for 5 different catalysts with different Cuwt% deposited at different spin speeds. Y column : Half life in seconds; x-column : deposition spin speed/rpm

Figure 5b Chart of calculated reaction Half lives (from data in Figure 1) for 5 different catalysts with different Cuwt% plotted against measured film thickness: Y column : Half life in seconds; x-column : measured film thicknesses.
