Version 1.0.0

Atomic absorption spectroscopy:

Atomic absorption spectroscopy (AAS):

• Measured the bulk concentrations using AAS
• Updated all figures to use the AAS concentrations
• Recalculated the loading efficiencies using the AAS concentrations
• Recalculated the hydrogen production rates using the AAS concentrations
• Updated all MATLAB Live Scripts to use the AAS concentrations
• Added the AAS concentrations to the documentation (instructions.md)

Energy dispersive X-ray spectroscopy (EDX):

• Renamed all instances of energy dispersive X-ray spectroscopy (EDS) to energy dispersive X-ray spectroscopy (EDX)
• Updated the EDX concentrations in edx_data.xlsx to only use 1 decimal place
• Swapped the columns of the EDX and AAS concentrations in Table 1 in instructions.md

Hydrogen production rates:

• Performed a one-way ANOVA to determine whether the differences in the hydrogen production rates are statistically significant

Documentation:

• Added the text "photocatalyst mass basis" to the hydrogen_results.png image that is displayed in the Results section of the readme
• Added the colour scheme used to represent the bare, copper-loaded, and platinum-loaded TiO₂ photocatalysts to instructions.md
